If you want a doctor who gives you straight answers and doesn’t sugarcoat things, Diane is the PCP you want. She’s not afraid to ask the tough questions or tell you the truth—even when it’s hard to hear. She can be warm and frienShow moredly, but she also gets right to the point, and that’s exactly why I appreciate her so much. She’s set me straight more than once, and yes, I’ve cried a few times—but only because I knew she was right. Honestly, it felt like having a mom getting on to me .LOL

From the minute, you walk in the door, you were greeted by a very friendly face even if you were having a bad day her smile would change it then being roomed I’m getting basic vitals. It’s almost like they become part of the familShow morey. They’re easy to talk to Mrs.Diane is amazing. I would not trade her for the world if you ever want to find a PCP that will listen to you have great bedside manner and has amazing office staff then go see Mrs Diane.

Mitchell D • December 16, 2025

Mrs. Diane is absolutely amazing! Even when she was in the hospital herself, she was still making sure her patients were taken care of. While in the ICU, she went above and beyond to ensure all of our medications were called in. If you want someone who truly listens and doesn’t feed you a lot of nonsense, you need to see Mrs. Diane. She’s the real deal — 100% I won’t go anywhere else!

Seen her nurse Jennifer Ottman and give them 5 stars for staying on top of complex patient care. They are always respectful and never seem to trade care for profits.
