We’ve now had the pleasure of working with Margaux and the On The Square team at Compass twice, and we truly can’t recommend them highly enough. Margaux really takes the time to get to know her clients—our preferences, priorities, and even things we didn’t realize we were looking for—and has an amazing ability to anticipate what we’ll love. Every listing and recommendation felt thoughtfully curated, and her advice throughout was always spot-on.
Margaux and the On The Square team are also just so easy to work with—warm, responsive, and incredibly dedicated. They’re always available, handle everything with care and professionalism, and go above and beyond for their clients. Working with them made what can often be a stressful process feel seamless, and we’re so grateful to have had them by our side!
A fantastic organization made up of great people! We have dealt with Mary, Margaux, and Fred and found them all equally amazing!!
My husband and I used Nancy Serpentine as our realtor to sell my father’s house in South Philly. From beginning to end Nancy was a top-notch professional and her company did an amazing job. Not only were they quick and efficient, but they made the whole process very simple for us. Her team did an amazing job getting the house ready for the sale and Nancy made sure it was all to her standards. Nancy is a realtor to put all your trust and faith into and she will not disappoint. I cannot say enough great things!!!
We had a fantastic experience working with Jeffrey Keller to sell our condo in Olde City, Philadelphia. From start to finish, Jeff was incredibly communicative, knowledgeable about the market, and always made us feel like a priority. He guided us through every step of the process with confidence and clarity, which made what could have been a stressful experience feel smooth and manageable.
The entire On The Square Team at Compass, including Sara Morris, was equally impressive—professional, responsive, and truly supportive throughout. Their coordination and attention to detail made a big difference in getting our place ready and sold!
If you’re looking for a realtor who is both highly skilled and genuinely a pleasure to work with, we can’t recommend Jeff and his team enough!
