Here is what my clients have written about me:


You are the best real estate agent in the world!  You are a scholar and a gentleman and a consummate professional.  Thank you for sticking with us for the last year or so and finding the most incredible house.  You are worth your weight in gold!


Ram & Ana


We wanted to express our sincere thanks for what you single handedly achieved in bringing our house to the market and obtaining such a wonderful price.  In addition, you handled every issue that arose, and more importantly you kept us fully informed and involved in the process from a distance of 2,500 miles.  We have worked very closely for many years with a close friend who became the finest agent in the country, but after working with you Marc, Audrey & I feel think that the huge gap Barbara Tyler left when she retired is yours to fill.


Colin & Audrey



We are writing to express our appreciation for the outstanding service provided by Marc Roos. We were delighted with his professionalism, honesty, hard work, caring attitude, cheerfulness, patience, and knowledgeable guidance. We've worked with many other Realtors® in the past, but found Marc to stand apart as a truly exceptional agent."
