"(Translated by Google) In September 2021 I went for a routine procedure, a colonoscopy, several benign polyps were removed, and I was lucky to have wonderful care from Doctor Guerra, who made me feel safe, and gave me assertive advice; “inform my brothers that polyps are hereditary”. My older brother followed his advice and saved his life, because he was operated on time, because his polyps were already malignant, he had no symptoms... I greatly appreciate and value your excellent and human attention. Thank you Dr. Guerra (Original) En Septiembre del 2021 acudí a un procedimiento de rutina, una colonoscopia, me extirparon varios pólipos benignos, y tuve la suerte de tener una magnifica atención del Doctor Guerra, quien me hizo sentir segura, y me dió un asertivo consejo; “informar a mis hermanos que los pólipos son hereditarios”. Mi hermano mayor siguió su consejo y salvó su vida, pues fue operado a tiempo, pues sus pólipos ya eran malignos, el no tenia síntomas… Agradesco y valoro mucho su excelente y humana atención. Gracias Dr. Guerra"
"I recently visited SA Gastro at 502 E Euclid. I had my colonoscopy done by Dr Ernesto Guerra, he was amazing was a quick procedure had no issues. Dr Guerra is highly recommended. Dr. Guerra and all of his staff were extremely nice, professional, and very friendly, they explained everything and were available for me at all times. I do want to say that John Rodriguez was so super nice on the phone, he kept me informed easy to get ahold of at any time. They followed up with me after procedure snd gave me a follow up appointment. Dr Guerra was recommended by my family and they have never had any complaints thank you Dr Guerra!"
"Dr Guerra is an excellent doctor, he’s very professional, caring, concerned & is sure to follow up. Dr Guerra has been my Gastrointerologist for a very long time & I trust his medical judgement. In 2018, I had a large polyp (tumor), that had to be removed surgically, however, the tumor was in a difficult area to get too. He’s guidance & further testing was essential in assessing & assuring that the Surgeon was successful in taking the tumor out."

"Reflecting on my colonoscopy prep experience let me say that the young man that called me to give me instructions was super helpful. I had a high copay for the prep and he help me by giving me a sample prep, Sutab. Sutab consists of nontasting tablets and plenty of liquids. The morning of, I was treated very well by every staff member. When I was wheeled into the room for the test. The nurse greeted me then the anesthesiologist introduced himself to me and explained how I would be sedated. I must add that Dr. Guerra introduced himself to me in such a friendly way and with humor. He told me that if all went well, I would get a “5 year or 5,000 mile warranty”. I truly felt comfortable. In recovery after I dressed, Dr. Guerra came by and very kindly shared the results. Yes, I got my “5 year or 5,000 mile warranty”. The nurse wheeled me to my vehicle and she to was joking with me and was very polite. Even though I was dreading this test, I must say my experience was very good. Dr. Guerra and his staff made it a pleasant experience."
"Had a great experience at the office. Staff were all friendly professional and helpful. I highly recommend Dr Guerra and his staff for any gastric procedures.

Also hands down to Dr Spencer she’s amazing."
