Patient Reviews
Jan 29, 2025
Dr Ohn misdiagnosed me as having pancreatitis. She lied about my blood work. She lied about my pancreas. She did an endoscopy and colonoscopy. Those records, along with others have been removed from my chart. She also created a second chart on me.She never once physically examined me. She said my daily vomiting was caused by pregnancy. I had a hysterectomy, there is no possibility of pregnancy. She knew about the hysterectomy.Dr Ohn was supposed to send me to St Louis. Almost a year later she still had not sent the referral.My doctor's can't access my records with her and we can't get into the portal due to her actions. I went for a second opinion and after testing, discovered it's gastroparesis. I'd lost over fifty pounds under her care and I'm terminal now bc of the misdiagnosis from this doc. I've been given less than a year to live. Thanks for killing me Dr Ohn.
