What John's Clients Say


With so many realtors to choose from, solid recommendations are oh so valuable. John was recommended to us and he delivered amazing service while being an absolute pleasure to work with. As we were moving from California, looking for a home had its challenges, but John's ingenuity and flexibility really made the process easier. When we were able to fly into the area, John's time commitment to us was amazing - allowing us to see a very long list of homes. He took the time to show us around the area too so we could envision where we'd grocery shop, workout, eat out, and other similar routines. When we were not in the area, John would tour homes with us remotely, via video. Other traits we loved: John is super knowledgeable on home construction and was able to bring aspects of a home (good or bad) to our attention. He is also quick to follow up on open questions/actions and gets the job done. John is really laid back too and not at all pushy or "sales-y". For us, he was that "calm" in what can be a stressful "storm" of a process. Again... we highly recommend John!

Matt and Joanne


John is a fantastic realtor and overall we are so happy we had him to help us in buying Our new home and selling the old home. He is very professional and always quick to respond. In addition, with his construction knowledge he was very helpful in our plans for renovating our new home. Would highly recommend John to others!

John was excellent to work with. His market knowledge and attention to detail was exactly what was needed for the sale of my home. The house went under contract 6 days after going on market. He truly made what could be a difficult task into a seamless transition. He always responded quickly to questions, and had all information we needed laid out professionally. I highly recommend him, and will seek him out once I'm ready to buy again.
