Everyone seems to know exactly what they are doing and Dr Guerra does a great job and makes you feel like you wellbeing is of the up most of importance. I am definitely not looking forward to my 5yr return appointment but at least I know I will be surrounded by caring people. Thank you"
"Dr. Guerra has been such a joy to work with in regards to my father's health. He puts my father at ease (which is hard to do), takes the time to listen and explain things. It's a shame when the office staff at the Euclid l9cation reflects poorly on him (and I'm sure the other dr's at this particular location as well). Since June 20,2023, I have called 8 times (today's the 8th of August) first, trying to get results, then leaving Dr. Guerra messages for his advisement, and now that all else has failed, trying to schedule an appointment to see just about anyone at this point. Regardless of the reason or situation, no one EVER calls back. The messages I leave does include my father's info and phone # so that cannot be used as an excuse. I understand there are other patients and do not expect any type of priority but come on, almost 2 months of calling and no response?!? Will strongly have to consider being referred to another GI Dr outside this group, which is a shame cause we really love Dr. Guerra."
"The entire staff was friendly, helpful, and very patient. The doctor was so understanding. He spoke to my grandma like a person and he didn't rush. He listened and responded."
