Margaux and the On the Square Team are a true rarity in real estate. Margaux and her team were knowledgeable, responsive, hands-on, and results oriented in their approach to sell our brownstone. They provided data-backed comps and Margaux literally went through every inch of our house and recommended how to get it market ready to maximize value. At the luxury end of the downtown Philly real estate market, the buyer pool can be thin – Margaux had a thoughtful and deliberate approach that got us maximum exposure on our listing and an offer after one of our first showings – under contract in 10 days! A phenomenal outcome for a process that we were quite anxious about going into it but felt at ease once we knew we had Margaux and her team behind us. If you are working with high end real estate in Philly, there is no better choice!

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.
