    I have worked in healthcare for my entire 40 year plus career and rarely have I been so fortunate to come across a provider that was as knowledgeable, thorough, and compassionate as Dr. Peppercorn. I was a new patient for him. I had to change providers due to insurance purposes. had very stressful event happened to me that day. He was just so knowledgeable about my history. He was so willing to listen to me and address my concerns. I just can't say enough wonderful things about him. And of course, in addition to being in the healthcare field myself, I've been a cancer patient. and also had my husband be a cancer patient and I just think he is a gem.
