Fairfax, VA |
Dr. Blosser is arrogant, aloof, rushes you through appointments and rather than try to get to the root of a problem, writes script after script without explaining how the medications work, risk vs. benefit. Really terrible doctor in our opinion with an incredibly poor bedside manner.
Washington, DC |
To be fair, all I have to go by as far as Dr. Blosser here is concerned is his "bedside manner". I followed the preparation instruction to a "T". Apparently, one of two things occurred; my body didn't react accordingly, or 2) they need to develop a better procedure for preparing patients for this procedure. Shortly after waking up I was "greeting" by Dr. Blosser with a sneering "horrible prep". So, again, he could use some work in the "bedside manner" department.

Many members of the staff, not all, are extremely rude. In particular, the male Anesthesioligist Or Nurse Anesthist , not exactly sure which role, was a complete jerk. He was talking down to the patient beside me in the waiting area for patients before going back for there procedure. Then about 5 minutes later he started berating some poor lady about who she was was and what was she doing there only to find out she worked there. Lastly, they never answer the phone or return a message.

Doctor for me for about 6 years. Prescribed me high doses of predisone steroid as a daily medicine cause he had no idea how to treat my condition. My intestines finally couldn't take it anymore and started constricting up. I made 3 appointments to see him and he said there was nothing wrong with my Crhons and that I was good. Told me to see my regular doctor as nothing was wrong. Went to ER and they said that I was low of everything and I was lucky to be alive. Emergency surgery fixed me!

Over 3 years of being misdiagnosed and shuffled out of the office without answers, yet mounting medical costs and new prescriptions. I'm do not believe Dr. Blosser or his team are driven to resolve patient issues or even properly identify them. Salt in the wound - the office staff in the Fairfax office are severely lacking customer service skills. Please do yourself a favor and go elsewhere for diagnosis and treatment.
Aldie, VA |
I'm not sure If I can find one word to describe him nicely. I had seen a lot of GI doctors and had to seek further help because my condition was not improving. Dr. Blosser was the last doctor I saw before I decided to remove my colon all together. His bedside manners were terrible. He was rude, inappropriate to female co-workers, and would easily become agitated. I figured his ability to perform as a GI would make up for his poor bedside manner, but I ended up losing my colon. I despise him.
in Reston, VA |
I can never get an answer when I call the office about ANYTHING. 2 weeks ago I called and also left a message on the online system, saying I'm not sure if my meds are working because I've still been having symptoms, including difficulty taking a deep breath sometimes. NO ONE has responded to me in all this time. And any time I call, I just get shunted over to leave a voicemail for someone, who then never calls me back. I don't get ANY answers. This is the poorest customer service ever!
in Washington, DC |
Dr blosser is a pompous arrogant Doctor. He does not listen to his patients symptoms and go forward with the appropriate tests. Saw him two years ago ; did an endoscopy ; gsve me stomach meds when he should have ordered a colonoscopy . One year later I was in er and diagnosed with stage 4 colon cancer . I could go on about his unprofessionalism when he visited me in the hospital .. But I'll leave it out. It was an upsetting display and then I never saw him again .
in Chantilly, VA |
I have a colonoscopy done by Dr. Blosser. I am very happy with the procedure and Dr. Blosser explained the result with me.
