reports of missed diagnoses or concerns in the past

"Dr. Powers was excellent. He spent 30 minutes with me discussing my concerns. He does not try to just move patients in and out. He cares and he tries to help you find root causes."

— UPMC Patient Review

"Dr. Gerlach is the best primary doctor I have had in a very long time. He is knowledgeable and prepares well for my visit. He doesn't pressure me for his recommendations, just explains risks and allows me to make my decision."

— UPMC Patient Review

"I would give them no stars if I could. They have a doctor by the name of Sarah mcelroy. My mom is now in the hospital passing away due this awful doctor egnoring how my mom was feeling."
