Excellent treatment, however, on each of my 4 visits the waiting time was excessive over an hour and a half each time. My recent appointment was at 8:00 am and I walked out of the office at 9:43 am. Treatment is quick but long waiting time are not the norm for Gonzaba physicians.

Dr Ana Ballester-Fiallo also advised me to loose weight. I told her Dr Gutierrez advocated the same thing and told me some of the discomfort I was feeling could be caused by inflammatory foods I’m eating. I bought a book about that and bought many of the foods I need. She also gave me lists of other things that could help.
Here at Gonzaba doctors work with each other, they are a team who help us, the patients, become stronger, healthier persons. They are a fantastic group of doctors building a better community!
