Ask Gary Therrien


I was on web site looking at houses and when I checked that I wanted to look at a particular house, Gary was the person who called me. We hit it off right away, and as things started spiraling, He took control and we eventually were able to find the house I purchased, which was itself a separate adventure. Through it all Gary was able to help me over the hurdles and navigate some pretty crazy waters.

Gary took such good care of me. Gary went beyound his job to help me. Gary is assent to Berkshire Hathaway!! He knows his stuff. I would definitely use him again.

Gary has been so awesome. We had the never ending listing. He got us into our new home quickly. It was selling the old house was the issue. We worked with Gary for 9 months, between showing us houses which was not easy. 3 house inspections the 3rd was the charm. Gary I think learned a lot from this, the craziness of selling a home and having several closing dates and changing last minute dates. He was awesome about options and keeping my temper in check. Gary has become part of our family and has done such a great job. Also Gary was referred to us thru quicken loans and what a team. Great Job Gary.

Gary made selling my home easy. Not living in the area is tough and Gary stepped up to help in all aspects to ensure everything well smooth and on-time. My house sold and closed quick! I would definitely recommend Gary if you are looking to buy or sell a home!!!!

Gary is incredible. If you are looking for someone who not only knows their stuff but also is super committed to finding YOU what YOU want... he is your guy. My fiancé and I knew very little about the home buying process. So when we met Gary, we had a lot of questions. Gary was very patient and walked us through the entire process. He was extremely attentive and would send us potential listings weekly. Gary was also able to find us a home inspector and mortgage broker. I would highly recommend Gary to anyone looking for a home. Whether you’re a first time home buyer or wanting to downsize... Gary can hook you up!
