About Me

As your REALTOR, I am dedicated to delivering on your real estate dreams. I am committed to keeping your needs and wants my first priority through the entire process of your transaction. Whether you are looking to buy your first home, moving to meet your expanding needs, relocating due to the military or other job prospects, or selling to adjust your home to your changing needs, I will devote my time and energy to ensure you encounter the best possible experience. I am always a phone call, text, or email away, and set a standard to make sure a client always feels valued.

With the support of CENTURY 21 New Millennium and its affiliates, I can save you time and stress during your real estate transaction. I have systems in place to help you find support through all the stages of the buying or selling process. I help you find support with your mortgage, title, settlement, insurance, and contracting needs. I believe very strongly that the moving process can be one of the biggest and most important experiences of your life, and I will always be in your corner as your agent to put out any and all fires so that you can focus on the excitement that comes with new beginnings.

A resident of Southern Maryland since 2009, and a metro Washington native, I have a firm handle on the markets of the area, and, as the wife of an Army veteran, I understand the unique needs of families moving to and from the metropolitan area.  I hold myself to the highest standards of honesty and care, and take an active role in my community. I am a wife and mother of three who resides on a small horse farm in Allens Fresh. I am involved in my church community with fellowship, stewardship like Safenights and food bank support, and in my role as a Sunday school teacher. I am a sponsor, board member, coach, and team mom for Charles County Youth League, and am also a Cub Scout den leader and Girl Scout volunteer.

In choosing me as your realtor, you are ensuring that you are choosing an agent who knows how to get the job done by my attention to detail and standard of excellence. I will listen to your needs and advocate on your behalf. I look forward to working with you!

Sarah did an amazing job helping me find my forever home. She was very knowledgeable about the area. She kept my best interests in mind throughout the process. She was very organized and kept on top of every issue we came across. She did an amazing job! Sarah was prompt with any changes that occurred and always made me aware of things immediately! Sarah was available whenever I needed her and was able to help reassure me when we hit bumps in the road. Everything start to finish was amazing!

I knew Sarah through our children participating in a local studio together. I saw how diligently she worked for her cli ents. Sarah was professional, accessible, and went out of her way to keep our home in the eyes of buyers. No matter what came up in the process Sarah was there, often before we knew anything had happen she had it resolved or a plan to resolve. I would highly recommend Sarah to anyone looking to sell their home.

Rachel & Ryan Crowley, Charles County
Sarah's service was excellent! We had a purchase that needed to be done as fast as possible. She was great at staying on top of the deadlines, being thorough, responsive, patient, and hand holding us through each of the many steps to make sure settlement on the house would still meet the shorter than average time frame we needed.
Review by
Joe and Margie Kilner, Frederick MD
Sarah was very friendly and kind from the moment we met for our first showing. She made sure to point out things that w e liked, disliked, needed improving, etc and made it clear that she only wanted what was best for us and was prepared to do whatever possible to get us the best deal. As previously stated, first time home buyers like us don't a clue what they are doing, and Sarah took the time out of her day to explain every small detail to us about what everything was during the entire home buying process from START to FINISH. Her help was greatly appreciated and she made us feel like family, and made our closing date very special with some personal touch. Thank you Sarah!!! With your help we got our beautiful place that we now call home. :-) I will reccomend you to all of our friends!
