My wife and I had the pleasure of working with John Gantkowski in purchasing our home. John is an amazing agent. He took care of my needs at all times of the day. He is very kind and very professional. He treated us like we were his family, and he secured the home buy. We had a road bump and John geared us out there. He is an amazing assets to his company and I am pleased to have worked with him. ...

John was amazing, I had a rough patch trying to get a house during COVID, and he helped me through the process. It was a new build. He was very knowledgeable, dependable, and responsive.

Bought a home in 2021 in Morgantown, PA.

Very fast to respond. Extremely respectful and professional. Willing to help you get what you are looking for. Never hesitated when asked about seeing different properties and would try and get us multiple properties to view in one day when time permitted. Made the process of selling our home quick and easy. Answered every question we had for him.
