Dr. Brenneman’s own patient experience as a young child drew him to healthcare. “My pediatrician was a mentor and role model for me. He included me in the decision-making for my treatments. That’s something that stuck with me, and I wanted to be that person for others.” Dr. Brenneman is passionate about helping patients through difficult diagnoses. “I do a lot more listening than talking in initial consultations. I recognize that it’s just as important as the diagnosis and the treatment recommendations to acknowledge and validate the patient experience.”
