Dr. Katherine Lynch speaking with a colleague.

Katherine Lynch, MD

For Katherine Lynch, MD, primary care is about long-term relationships. “Every time I see a patient, my goal is that we develop a more lasting bond,” she says. “I want them to trust me and feel comfortable with me. I also want to know about their family, job, hobbies and what they care about.”

Dr. Lynch looks for the mind-body connection: the way the mind can affect one’s health in subtle or major ways. “Someone may come to the office with shoulder pain, but are there other things going on?” she asks. “I keep an open mind about how mental health affects medical health. We are fortunate to have behavioral health providers working with us to make sure our patients receive the care they need.”
