My name is Brian Keith Johnson, and my wife and I have both been patients with Dr Dietrich. He has done two prior procedures on her and two on me, both with great success. Though I was supposed to write this review after my last appointment in August, I failed to do so in a timely manner, but I figured that later is better than never. There is a reason (not an excuse) for my delayed review. I am a professional opera singer. Since I retired from my 35 year public school teaching job last year, I have been singin... read more

The process of having to get a colonoscopy done is very unorganized. My doctor told me in August 2025 that I would need one and I was told that I would not be schedule until the end of October 2025. I was later told that it would not be until sometime in February. I had to call my doctor and complained and then was finally scheduled in November 2025. I finally receive the document for the colonoscopy by email. The document stated I need to pick up my prescription, does not state where, meaning is that at my pharmacy o... read more

I’m honestly heartbroken to have to write this, because I truly admire the doctor — he’s caring, knowledgeable, and someone I trusted completely. But the office staff has made every visit a stressful and upsetting experience. They are rude, unprofessional, and speak to patients in a condescending way, as if our time or concerns don’t matter. It’s so disappointing to see such a great doctor surrounded by a team that lacks compassion and respect. No one should be made to feel small or dismissed when seeking medical care. I’ve... read more

My girlfriend was put on emergency status for a colonoscopy. After problems with both ends of Doctor's offices not communicating or submitting forms with the insurance, I proceeded with a 4 way call and got all parties to approve the requests. It was 4 weeks of misery and anguish which she's still experiencing. The pregnant lady that was in the office at Dr Dodda's was the ONLY concerned and considerate person there. Others should take NOTES from her. We were only consulted when Dr Dodda arrived to the appointment and no p... read more
