Ask Gary Therrien


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!
