    Dr. Denny was very friendly and I feel did her best to get to the bottom of my problem and try to find relief for me - she treated me better than most other doctors.

    Dr. Denny is the best! We love collaborating with her for the best care for my mom.

  • May 6, 2024

    Dr. Denny is without a doubt the best doctor I have ever had in my 77 years. I've had several primary care doctors who have been helpful, empathetic and talk to me and answer questions but she is so thorough in providing me with information and addressing my concerns. She discusses alternatives, test results, always lets me know what she's thinking while we're talking, reviews test results conducted by my local hospital with me, offers to reach out to whatever specialist I'm seeing locally to coordinate my care, etc.
