I had a fantastic experience working with Jason Kassimir with the Hay & Holt team. I lived out of state and Jason was always accommodating my busy schedule, working odd hours and fitting in a jam packed viewing schedule. He was also very prompt at finding answers to my questions and following up on details before and after the sale. Thank you for that Jason! I highly recommend!

Jason was great to work with, and found us our dream spot on our
first-day viewing! Would highly recommend working with him! Ian Spear

Jason was absolutely fantastic--thoughtful, efficient, responsive. He
was there with us every step of the way and made everything
frictionless. We had an excellent experience and will recommend
Compass and Jason to our friends.

Jason and Nicole were very knowledgeable, efficient and fun to work with during a very challenging time. In the middle of the pandemic they were frequently our eyes and ears as we looked at properties from afar and they helped us find the perfect spot.
