I wish I could say how grateful I am to Dr Vierra for performing a life saving surgery on my best friend. I am not because the Dr refused, instead prescribing the misnamed “comfort care” with the only cogent reason for not saving her being she was too backed up for his tastes. Compassion care is high dose morphine, which the hospital had already determined my friend did not tolerate, intended to make death more comfortable, it did not, and this was for an injury that occured 70 years prior.

Dr. Vierra did my gastric sleeve surgery and gall bladder removal in June 2015 and during the surgery, plus pre- and post-op, I received excellent care. The surgery was more difficult than he expected, but he persisted and removed my gall bladder (which was full of stones and scar tissue), and my pain level immediately decreased. My weight loss has improved my quality of life! Dr. Vierra is very thorough, skilled and caring. His entire staff is great, too, and follow-up care is superb.

Dr. Vierra saved my life. I had complications from lapiscropic colon cancer surgery didn't show up in the C scan until I was in critical condition with sepsis. Dr.Vierra preformed a six hour abdominal surgery knowing that it would take a miracle for me to survive. Dr. Vierra was there for me and my family every minute. Dr.Vierra is an amazing doctor AND an amazing human being. It's a little over a year since the surgery and I am doing GREAT! 10/06/2016

Dr. Vierra is professional, competent, knowledgeable, and compassionate. He was very thorough in explaining my condition. I will definitely continue to see him as needed and would highly recommend him to friends and family. He takes his patients seriously and is open to answer questions and address concerns.

When you think of the sterotype of a doctor who thinks he's God and is above his patients, this exactly fits this man. I would rather be in pain for the rest of my life than have to deal with this MAN again.
