Patient Reviews
Oct 20, 2025
I had a very disappointing experience with this doctor. After years of struggling with severe gut issues and even losing feeling on the right side of my body, I was told that all of my problems were 'in my head' and that I should seek therapy. I left feeling completely defeated and unheard.After finding a GI specialist and undergoing proper testing, I was finally diagnosed with Gastroparesis—40% of my stomach is paralyzed. To be dismissed for so long when something was truly wrong is incredibly disheartening.If you’ve had a similar experience, please remember: you know your own body. Never stop being your own advocate. I truly hope this provider takes the time to research complex cases and listen more closely to patients instead of defaulting to assumptions when symptoms don’t fit a basic diagnosis.
