I don’t know of a kind of more attentive physician surgeon than Dr. Brian Cook. Not only that, but his staff is just as friendly. They’re very efficient and anytime that I have ever been there, I have never had to wait more than five minutes. Another impressive part of this doctor is that even though he is attentive to his patience and may have had to do surgery all night, he still saw everyone scheduled to see him with the kindness and quality that he always sees everyone with.

Dr Z is an excellent caring physician. He has explained everything to us in a very detailed and methodical manner. Also, after an office visit today his staff was found to be very professional and caring.

The doctors and staff are wonderful! I had a liver resection done 3 weeks ago and cannot say enough good things about the way I was treated by the entire staff of this office! Dr. Gagnon is patient and makes sure to spend time, during your appointment, to explain the surgery and answer questions. I even sent him an email, after my appointment, to ask even more questions which he answered right away. Dr. Gagnon did a wonderful job on my surgery! Because of Covid my husband could not be in the hospital during my surgery (only the patients are allowed in the hospital) and Dr. Gagnon and his nurse called my husband several times to update him on my progression. The surgery was over in 4.5 hours (the average time under is 5-7 hours) so I was happy to not be "under" as long as I could have been. I am very relieved and happy to have had such excellent care. I highly recommend Dr. Gagnon!

Their staff and doctors are amazing. They are always egar to help, kind and professional. Also and perhaps most important, THE ABSOLUTE BEST liver and kidney surgeon in the state and possibly beyond works here. Dr. Zendejas performed a life saving liver resection on me last September. He was able to remove the entire right node of my liver and a softball sized cancerous tumor. I was told by other doctors that chemo and radiation we're my only options and the I was basically going to die. Well in 3 weeks I will be 1 year disease free because of Canyon Surgicals team and Dr. Zendejas.
