I cannot say enough about how grateful I am for Dr. Mairs and his entire medical team.I have been his patient since 2013, when he helped deliver my daughter alongside another physician. From that very first experience, he demonstrated a level of professionalism, calm confidence, and genuine compassion that left a lasting impression on me.When I recently learned that Dr. Mairs had returned to practice, I canceled a surgery I had already scheduled with another provider — just one week before it was set to take place — so that I could be under his care instead. That decision was easy because the trust I have in him is absolute.Dr. Mairs listens carefully, explains things thoroughly, and never makes you feel rushed or dismissed. He treats you like a person, not a chart. In moments that feel overwhelming or uncertain, his steady presence and thoughtful approach bring reassurance and clarity.His return to practice is truly a gift to his patients and to this community. I am incredibly thankful to once again have him as my physician and would recommend him without hesitation to anyone seeking skilled, compassionate, patient-centered care.I’d also like to add that Dr. Mairs’ absence was deeply felt in this community. When he was no longer practicing, many of us were left navigating limited options and trying to find care that matched the level of skill, attentiveness, and trust we had previously experienced with him. While there are certainly other providers, the standard of care he brings is exceptional and not easily replaced.For many patients, including myself, his departure created a noticeable gap — not just medically, but relationally. It is rare to find a physician who combines clinical excellence with genuine compassion and consistency over years of care. When that kind of provider is no longer available, it impacts more than just appointment schedules; it affects patient confidence, continuity of care, and peace of mind.His return has restored something that was missing. The community is stronger with him practicing, and his presence truly elevates the level of care available here.
