Melissa Martin
Transaction Manager

Melissa worked as the Operations Director for a large, top producing Real Estate team based in DC for over 7 years. Over this time, she assisted in closing over 500 successful transactions while managing the brokerage, handling social media, and training new agents, as well. She will tell you that she found her true passion when she began working in real estate in 2014. She admires the amount of dedication and time that great REALTORS® put into their work and enjoys being able to take the "busy work" off of their plates, so they can focus on their clients and building their business.


“What we do is important. I never underestimate the value of this work. I understand that for most people, buying or selling a home is one of the most important personal decisions, and possibly the largest financial decision they’ll ever make. It is my main concern to tailor each sale to the individual needs of each of my clients, and their buyers and sellers, in order to make this process as easy and stress-free as possible."


When Melissa is at home you might find her watching Food Network and either planning a new recipe creation or dreaming of her next foodie excursion with her partner, Jon.



Sarah Herrera
Transaction Manager

Sarah started her career in Real Estate in 2002 as an assistant to several agents at a small brokerage in Oceanside, California.  During her time there she managed the marketing of listings as well as daily office duties.  In 2004 Sarah decided to further her career and began working for a small mortgage company as an assistant to a loan officer.  As her love for the mortgage aspect of the industry grew she worked her way up to being a lead post-closer.  After the birth of her second child she decided to put her career on hold to be a stay at home mom.


In 2019 Sarah jumped back into the Real Estate industry when she was given the opportunity to join a successful Real Estate agent as her Director of Operations and Transaction Coordinator.  This opportunity opened up her eyes to her true passion and calling in Real Estate -- as a TC!


Few things make Sarah happier than assisting agents with the parts of the Real Estate process that take time and energy away from what they love doing -- connecting and building relationships with their clients.
