Seemed like a nice person, BUT... Went in for a routine colonoscopy, was bruised internally during the procedure, & ended up in the hospital 2 days later w/ severe abdominal pain. Now paying off my $5K worth of co-insurance for my day's stay at the hospital (which is where his office directed me). I liked this facility and had an excellent prior experience there (different Dr), but this whole experience was expensive & aggravating (w/ a $300 office bill on top for him to tell me he bruised me).

He's straight forward and direct. That may put some people off, but I'd rather know what I'm dealing with and how easily fixed.

Dr. Tosseou has horrible communication skills with patient and patients family. He never called once when test results came back; leaving me to interpret them myself from the online report. Also, he should not talk about patient when just receiving anesthsia and still fully awake. Dr. Tosseou has good skills with procedures, but horrible bedside skills.

Great he is very pleasant. Takes time for all the issues. He was very respectful of my nursing background and not condescending discussed med history. Had good discussion about RX, procedures and prognosis r/t to my complicated list of problems I appreciated his honest approach without any sugar coating as per my liking in a MD. He is a very caring and impathic individual. He is a keeper and understood my sense of humor. I will enjoy working with him
