About Prince Frederick Office

Our office is conveniently located in the center of Calvert County in Prince Frederick, Md, also the county seat. Steeped in historical significance and surrounded by water and natural beauty, it is easy to understand why people have chosen to make Calvert County their home since 1654. The county has a total area of 345 square miles, making it the smallest county in Maryland in terms of land. Much of Calvert County is a Peninsula flanked by both the Chesapeake Bay and the Patuxent River.

Once made up primarily of farms and tobacco fields, the county has become a fast-growing exurban neighbor of Washington, D.C. Many home prices have nearly quadrupled in the past decade. The county has one of the highest median household incomes in the United States. With so much going for it, its hard to believe that it is still one of the most affordable places to live in the D.C. metro area.

While many residents make the 30-mile commute into D.C. for work or hop over the bridge to Patuxent River Naval Air Station, Calvert County also provides its residents with great job opportunities. The top employers are Calvert County Government, Calvert Memorial Hospital, Constellation Energy, and last, but actually largest, Calvert County Public Schools. The schools are continually ranked as some of the best in the state and certainly another reason our residents choose to live here.

When our residents are not at work they enjoy all that the county has to offer. Some of the highlights include:

  • Chesapeake and North Beach, and the quaint towns named for the beaches
  • Solomons Island
  • The Calvert Marine Museum
  • Several local wineries including the award winning Running Hare Vineyard
  • Ann Marie Sculpture Gardens which features year round events to cater to everyone.
  • Cove Point Light House
  • Calvert Cliffs State Park
  • We are also just a short drive from historic St. Mary’s County and Annapolis, Md., home of the U.S. Naval Academy and many other tourist attractions.

Patti was great! She got a full price off on my house. The communication couldn't get any better. I will use Patti in the future and will recommend her to others.

Kelly DePaulo Dunkirk
I can't say enough great things about Mark Frisco and his team!!! They were wonderful getting me through my ve ry first home purchase, oh, and did I mention it was a short sale... lol. I moved here from PA to be closer to my daughter and ended up living with her and my son-in-law for 8 months!!! You can't get much closer then that but Mark and his team did a fantastic job getting me into the home I wanted. Once we got third party approval from the bank they were on top of things, they immediately set up the inspections, appraisals and were getting everything done to get me into the house as soon as possible and they did!!! We had closing on May 10th, a week or two earlier then expected. I couldn't be happier. They were there for me every step of the way. If I had a question Mark got back to me immediately and that was only if Katie wasn't positive about the answer (sweetest person ever, that girl!). I will definitely be recommending Mark Frisco to anyone buying or selling their home, I couldn't be happier. Thank You Mark Frisco!!!

I was assigned to Karly via Navy Federal's Reality Plus program. Knowing what I know now, I would recommend an d have recommended Karly to others and will continue to do so. Karly was extremely knowledgeable and helpful in all aspects of our requests. She was always willing to look at numerous properties at anytime of the day to facilitate our needs and schedule. She was absolutely perfect in all aspects. I can't say enough on how excellent Karly was in all above mentioned aspects. To include all previous mentioned comments, she really was an awesome realtor. Century 21 as a whole was incredible. Dave from Bay State Title Company, recommended by Karly, was also fantastic.

I had been a Realtor with Century 21 New Millennium for many years and had worked closely with Elaine Flowers. I was aware of her abilities and performance record and was pleased to list our property with someone of her caliber. Elaine always kept us informed of the status of contracts during the sale of our property. She was prompt in transmitting all information even when it was less than favorable. We could contact her with any questions at any time and she was always willing to help in any way she could. We received multiple offers on our property, and Elaine presented each one in detail, outlining the pros and cons of each contract. Unfortunately we did experience some difficulties with the specific contracts that we chose, but Elaine dealt with each situation professionally and efficiently so that we could move forward with the sale of our property. We would recommend Elaine Flowers to other homeowners who are looking for a Realtor who is knowledgeable, experienced and patient.

I don't think I could find another fair and honest agent to represent me and help guide me along the way quite like she did. She has a lot of experience and knowledge in her field which I appreciate. She made recommendations on how to sell our home quickly and she did just that. We were thrilled to have our home under contract in less than 30 days. I would hands down recommend her to anyone in the market looking to either buy or sell their home. She does all she can to make her client's experience both enjoyable and effortless! I haven't encountered a person yet that has regretted using her as their agent! She's great :)

It was a great experience and an extremely outstanding service from Mrs. Trish Frostbutter. I will choose her again and refer her to all my friends and family. She is very intelligent and vibrant! Yes, I am very satisfied and love to work with Mrs. Trish Frostbutter in the future and when needed. Greg Connarn, an excellent realtor thru Century 21 referred me to Trish Fristbutter who she is a top notch and extremely professional, helpful, a person to person relation, very knowledgeable and outstanding service. I just love her attitude, demeanor and her customer service skills. She is No. 1 and the BEST. I am so happy I found her during the whole process of selling my house. OUTSTANDING! SUPER! Excellent Service!

Patti was simply a great person to work with. She always answers your questions and gets back to you as soon as she can with phone calls, and always seems to be very happy when she shows a house. I would recommend patti to any friend or family member if they wanted to have a great home buying experience. Patti never made it seem stressful, as with buying a home can be, it was a delight to work with someone like her and she will always come highly recommended from me.

Linda by far went above and beyond her normal duties in helping me get the home sold as I was an out of state seller. Further, Linda clearly knows the market and has the experience to provide sound advice to get your home sold fast and at market value. I listened to Linda, put a good amount of money into freshening up the home, staging, and landscaping, and my home sold for asking price in 4 days. I assure you, had I not listened and took Linda's advice the home would still be for sale and probably have a $30k reduction in price.

Mark and his team were amazing. We were very nervous buying our first home but Mark helped make the entire pro cess so smooth for us. He and his team always made sure we knew exactly what was going on at all times and were readily available. Mark's knowledge of the housing market and home buying process made me feel comfortable at every point in the process. With his help we were able to negotiate a great price on an awesome house. I couldn't imagine having a better experience with buying our first home. Mark and his team are top notch. I never met someone so willing to help and make things as easy for you as possible. I will definitely be using him again for any future home buying and selling. Mark was very professional while still being very approachable. He made us feel comfortable asking every and any question we had and we fully trusted his answers and advice. The team at Century 21 was also outstanding. They always made sure to keep us informed of everything that was going on and went the extra mile to make appointments convenient and easy. Overall experience was great. I cannot see how I could have had a better experience than the one I had with Mark Frisco and Century 21.

I wouldn't hesitate to use Mark Frisco of Century 21 New Millennium again if I were to sell my home and I woul d definitely recommend him to anyone who was looking to buy or sell. Mark is a very caring agent and acted in a very professional way and I trusted his knowledge and guidance through my short sale. Thank you Mark!

Linda is very knowledgeable about the southern Maryland area. She was very responsive to our needs and went th e extra mile on more than one occasion. I would highly recommend her.

Jane Ervin, Port Republic, Maryland
We had an offer in two days, signed contract two days later. Miss Utility had not marked the property yet so t he sign could not go up.We apparently did not need it anyway :-) Mark Frisco sold a friend's house in eight days, this was even faster! These positive comments apply to Mark Frisco, but also apply to his team, Tiffany usually had contacted the various inspectors for the answers before I even called her, and kept me up to date on all the scheduled inspections.

Mark Frisco took the time to fully understand my needs, then paired me with a team member which was best suite d to provide dedicated attention and time. Mark also followed through to ensure my needs and objectives were being met, and I was fully satisfied with all aspects of the experience. I appreciate the "entire team" of professionals that handled my transaction, well done! Special call out for Tracy, who demonstrated great patience and professionalism while we honed our idea of the perfect house. Thank you!

We were referred to Debbi via USAA. She showed a strong understanding of our needs and requirements. I was n ot concerned about broker commission. Debbi showed tremendous local knowledge. I was recommended to Debbi by USAA and would recommend her to anybody. This was my first time working with Debbi. Debbi met us on a Monday and had a binding contract on the home of our dreams by Monday. I learned everything I know about Calvert County and Southern MD from Debbi. She was patient with my snail mail escrow money. Debbi saved $10,000 for us during negotiations for this house. Debbi showed incredible attention to detail and was very informative during the inspection. Debbi was a joy to work with and I will definitely work with her again. She showed us great options in addition to the home we purchased through her. Most of this transaction took place long distance for us. Debbi was our eyes and ears and made the experience as stress free as possible. I met with the individual at the front desk on the day of closing and she was very polite and professional.

St Leonard, Maryland
Conventional wisdom tells us to not do business with friends, however due to our 20 year friendship with Patti O we knew first hand of her integrity and strong work ethic. Listing with Patti was an easy decision ; but once we were under contract we realized it was a WISE decision as well. We had wonderful buyers that came with agent unfamiliar with the area. This is when we learned how important the agent WHO represented us was. Patti made certain all required inspections and repairs were done promptly and correctly and communicated with a rather frustrating title company as well. By Patti being PROACTIVE were able to close quickly to satisfy the buyers wishes. Patti comes with the knowledge of not only WHAT need done but WHO to contact. This is so helpful for a seller when they first list their home and also once under contract. She can assist sellers with item such as landscaping, power washing, well, septic, electrical to name a few. Patti also provides quality pictures , video and brochures. Patti understands that selling or buying a home is a stressful life event and is always available when you need her. We can recommend with out reservation Patti O'Donnell at Century 21 NM to anyone looking for a TRUE real estate professional.

Trisha Frostbutter is simply the best agent we could have asked for! She eased our stress level during this no rmally stressful time in life.She was the sweetest and understood, selling my childhood home was going to be a challenge for me, but was supportive from the start with a smiling face and a tissue when needed. She shared her knowledge of the selling process with us, as this was our first time selling property. She was prompt and professional during all interactions. She kept us updated through every step of the way. I couldn't have asked for anything more. Her kind and genuine spirit shined through from the moment we first spoke on the phone.

Josh english Port Republic
I rated Trish in these areas as "excellent" because she was. She provided updates and status as well as made recommendations. Just her being in regular contact with us made the whole process manageable. She provided clear timely communications and at all times listened to our needs and concerns. I will recommend Trish to anyone in Calvert County, she is a top notch professional. The whole process was a year long experience but this was not due to anything or any body, it was the market. Working with Trish made this bearable and at the end we got exactly what we wanted and it was easy settlement. I am sure that Trish handled a lot behind the scenes and I do appreciate her doing so. If I was to buy in Calvert County again, we are now renting and have lived in the county 34 years, I would go directly to my friend and adviser Trish. I value her experience and knowledge in this market. Trish contacted a professional photographer, which I think did an amazing job on the photos of our property. We did put the house on the market during the "slow" season but even with that we had as an average 3 people a week viewing the house. Trish provided recommendations, which I followed and at the end, even though the house was on the market for just about a year, when we did get the buyer it was quick and effortless on our part. A solid buyer with reasonable expectations. Also in closing we did not get our check because of the remote closing as expected, Trish addressed this with the title company and it was all handled professionally with a good end result for us.

Debbi went the extra mile for us...more than one, as we covered a tremendous area with our search. She follow ed up with sellers' agents, inspectors, appraisers and others to make sure our search and ultimate settlement happened on a very tight time schedule. She really made the overall process enjoyable!

Jeff and Katy, Cobb Island
Patti O'Donnell is an agent that is always available. Of course, they're are times when you call, it goes to v oicemail, however, she calls back with in a few minutes. Patti was scheduled to be on vacation at the tail end of our process but she was never out of reach. I felt very guilty about contacting her while she was on vacation but she always assured me that I may call her anytime. Patti never made me feel like I was interrupting her and I was never rushed. She even came back from vacation early just to be there with us during the settlement. I would absolutely recommend this Broker and Agent to anyone who wishes to deal with someone who really cares about what you want and will go over and beyond to make that happen.
Review by
Janelle Sears, Lothian
As a first time homebuyer I really didn't have many expectations because I wasn't knowledgeable regarding the homebuying process but from the first conversation, I could tell that Trish would take care of us. She understood and cared about our unique needs of having to close very soon due to my job transfer. I spoke to a few other agents but Trish's compassion really stood out. She worked tirelessly to assist us throughout this process and got us to closing in 30 days! She explained the steps and kept is involved with how things were progressing. Trish is now apart of the fam! How could we not use her again!?!
Review by
The Fontaine's, Waldorf MD
Since we have only sold our homes twice in the last 40 years we were interested in someone that was knowledgea ble, trustworthy and communicated well with us. Elaine delivered exactly what was promised and her follow up was excellent. When a last minute repair was needed or we needed decluttering services, Elaine handled it for us. Since we used the relocation service, Elaine facilitated and assisted when necessary to ensure we had a new residence before closing. We would highly recommend Elaine because of her superior people skills, knowledge of our area and great follow through. Mike & Kathy Centra

Patti O'Donnell was very thorough when explaining everything about the home we were buying when preparing the contract. From the deposit and how it was handled to her timely scheduling of inspections and the negotiating of contracts. We had an issue with selling our home which held up buying this home and Patti kept us up on everything and helped us straighten out the problem.

Mark Frisco could not have been any better an agent for our family! His knowledge of the local market and acc ess to potential buyers were integral to our success. Even though Mark and his wife we expecting their first child, Mark was easily accessible. He even came from the hospital to our settlement when his newborn baby was only two days old! I wouldn't have expected that service from anyone!

Patti O'Donnell is an awesome real estate agent and I would recommend her to anyone looking to buy and/or sell a home in the near future. Her knowledge of real estate buying and selling made our sale and purchase go smoothly and her attention to detail is amazing. She stayed in touch with my husband and I throughout the entire process. If we ever decide to move again, we will definitely use her services again.

Mark and his team completely surpassed all expectations that we had. Although I can be high stressed at times Mark's knowledge of the business gave us the confidence we needed to move forward. I had no idea what to expect and everything good I was hoping for he delivered. I couldn't ask for anything better! Well there is one thing that I wanted but didn't get; 6 of Mark's best friends to show up on my moving day willing to pack and move my entire 5 bedroom 3 level town house with 600 stairs. But I'm sure if I asked he would've delivered that too.

Anthony Rivera, SGT., US Army, Retired, Mechanicsville, MD
We wanted to use a broker that was familiar with the local market We could not ask for a better sales agent t han Mark Frisco. He helped us in all stages of selling the house to include recommendations for house prep for sale, providing names of contractors, greatly helping us through the closing process, and ironing out the inevitable glitches that come up during the process of selling a house. He was very knowledgeable in the requirements for listing and selling homes. Mark was great. The assistant Tiffany also helped us a great deal.

Mark Frisco worked out proper value for house and got it sold quickly. I lived in South Carolina and wanted to sell me parents house as painlessly as possible and Mark Frisco did this while making sure I was kept up to date with everything that was going on with the sale of the house. This was the second house Mark Frisco got sold for me and I would definitely recommend him.
Review by
Skip Stortzum, Myrtle Beach, SC.
I had a unique case in which I needed to move into the house prior to closing with relatively short notice. M ark Frisco's team (particularly Tracy Mellor) made this happen with no issues at all. Tracy was able to walk me through each step of the buying process which was extremely helpful since I honestly had no clue what I was doing. Every step was clearly explained and done in a timely manner. The entire Mark Frisco team was tremendously helpful throughout this entire process and I would highly recommend them to anyone looking to buy or sell their house!

Karly Rosasco: Throughout the home buying process Karly represented herself and Century 21 New Millennium in the most professional manner. I would highly recommend Karly to anyone shopping for a new home. Karly was very attentive to our needs as home buyers; she asked detailed questions to learn what was best for our family before starting the home buying process. Karly was very patient and took the time to show us many homes before we found the perfect home for us. Karly stayed engaged the entire time, once the contract was written she addressed all of our concerns with the agent and builder/ seller of the home. Karly gave us sound advice and worked hard to get us the best deal possible while at the same time managing our expectations. Karly proved to be very knowledgeable of all the steps in the Real Estate buying process. I would certainly recommend her to any family member, friend, or stranger looking to buy or sell a home. -Frank Stone
