We enjoyed working with Mary Colvin. She was truly a professional and made herself available at all times. She guided us through some particular situations and helped us attain our goal of selling our condo. She and her team definitely know the market and I recommend them.

My time with Nancy Serpentine was actually serendipitous. After some unexpected changes in a prior contact, Nancy picked up the ball and got me into my home, closing in less than two months. Nancy was able to crystallize my vision and present the property that exceeded my expectations. I’m grateful for her acumen as well as divine destiny. I’m very pleased and at peace.
Thank you.

Phyllis went above and beyond for us throughout the entire home-buying process. She was consistently willing to do more than we could reasonably have expected – and helped us find the perfect house for us in a challenging market. We felt extremely well supported throughout and would recommend her without hesitation.

We collaborated with Margaux, who diligently assisted us throughout the entire process, from our initial visit to providing us with options on the selling strategy and ensuring our success until the very end of the closing process. Margaux possesses an unparalleled knowledge of the center city Philadelphia area.
