nice person

09/15/2025

I cannot say it enough, it's taken me years to meet a medical caregiver as comprehensive, thoughtful and thorough as Ann is. Whenever her name comes up in general, I can tell you everyone says the same thing about her. And, the same for your office staff. Always respectful, kind and helpful. I actually look forward to coming to your office!

05/13/2025

As said, I searched a long time before finding someone like Ann; who not only listens to me, but hears what is actually being said. This was especially crucial when my son died suddenly in June of 2024. She carried me through an absolutely horrific period of time. While I am still grieving deeply and will never get over the his death, her kindness and compassion eased the worst of the shock.
