Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Fantastic Experience with Dr. Umbach and Team
I have never had such a warm, caring experience in a surgery before! The entire team was just amazing -- from Alex, Nicole, Carl, and especially Dr. Umbach and the nurses, just WOW. They really do care about you and did not make me feel bad about the situation I was in with my weight. Thank you!!!

Highly Recommend Blossom Bariatrics
The entire team at Blossom is so knowledgeable, kind, and took such great care of me before, during, and after my procedure. Even their driver for pick up and drop off at the hotel was incredibly supportive and kind. Dr Apel is so knowledgeable and has a great bedside manner. He thoroughly answered all of my many questions, and really made me feel comfortable. He also took a photo of the removed portion at my request! I am so happy that I chose Blossom Bariatrics for my procedure.
