Philosophy of care | Listening is important. That's the most helpful to patients. You get the most insight into their personality. Communication is also important -- not only with the patient, but with the patient's family, and especially in the hospital or nursing home. Good communication goes a long way. I've been doing this for more than 10 years, and you build a relationship with your patients. I like to catch up, see how they're doing, ask about their family, vacations. | Why I entered medicine | My father was a doctor, and that had an impact on me when I was growing up. | Personal interests | My greatest passion in life is my family -- my wife and my two daughters.

Philosophy of care | I believe in treating patients as equals and friends. When a patient visits, I want to make them comfortable when they share what’s happening with their health. I don’t like to lecture people, but I believe it’s important to educate patients about preventative medicine. It’s important to catch small issues before they become big problems. It's very enjoyable and very rewarding, particularly when I see patients in the hospital – and in the office – to know that what I am doing has an impact. I also like to find out what's going on in their lives in addition to the medical aspects – with their grandchildren, where they are going on vacation – just meeting people every day and getting to know them. | Why I entered medicine | Growing up, I played football and basketball in school, and I was always interested in how the body works.

My goal is to partner with patients and empower them to get involved in their care. | Why I entered medicine | Early on in school, I noticed I most enjoyed classes about health and the human body. As my medical training progressed, I discovered there’s so much more to being a physician than prescribing and diagnosing.

Philosophy of care | I believe in a patient-centered approach to medicine. That means treating my patients as individuals and really focusing on their personal preferences, values, cultural traditions and lifestyle choices. It also means giving them the tools they need—as individuals—to take care of themselves. The old way of medicine – when people see a doctor once they’re already sick – is clearly not working. Today’s approach focuses on prevention, and I am passionate about spreading the message. The goal is to get people into the doctor’s office early, before problems begin. Then, we can work as a team to create the healthiest future possible. I strongly believe in the 'patient-centered medical home' concept. | Why I entered medicine | I always envisioned helping other people and making a difference.

I like that the only thing you need is a pair of sneakers. You can do it anywhere, anytime. Once my feet hit the ground, I can focus on the motion of running without any other thoughts racing through my head. It’s my stress relief, and it really works for me. I’ve run several 5K and 10K races. I just completed my second half-marathon, and I hope to do a full marathon in the future. Dr. Calhoun is highly rated in 3 conditions, according to our data.
