After meeting with Jon, he understood exactly what we were looking for in a home. He was extremely knowledgeable about different home styles and knew what to look for regarding any potential issues structurally or otherwise. Jon was always very communicative and available when we needed him. One of the homes he sent us ended up being our dream home. We were in a competitive situation but with his help we were able to present a great offer and negotiations went smoothly with minimal stress. After we went under contract, Rachel kept us updated and on track for a smooth closing. They helped us set up insurance and utilities and helped us feel very well taken care of. We highly recommend Jon St. Pierre and the Zoeller Group to anyone looking for a home.

We originally started our home search with Alex and from the very beginning he made us feel confident and comfortable with the firm. As first-time buyers, that reassurance meant a lot. We ultimately purchased our home through Ezra due to his licensing in Maine, but Alex continued to support us throughout the process, even stepping in for some walk-throughs and inspections. His dedication to making sure we had a positive experience stood out. He is incredibly informative and knowledgeable. I learned so much from him early on that I carried with me into future showings and decisions. We give him huge credit for helping make this purchase possible.

Jon St. Pierre helped us get into our very first home! He and his team were so knowledgeable and patient walking us through the process. They really helped us feel confident through each step, and I honestly can't imagine how stressful it would have been to have to navigate it all on my own. 100% recommend!

We had an amazing experience working with Lillian! She made a complicated process feel smooth and simple, especially as a first time homebuyer. She was extraordinarily responsive, even getting back to us on nights and weekends, and took care of all communication with the seller and title agent so we could focus on financing (which she even stepped in to help with many times). Highly recommend working with Lillian and the team!
