Testimonials

Went in for a first time colonoscopy and I was a bit nervous on what to expect. Thankfully the nurse and staff were very nice and helpful at putting my nerves at ease. Had it done and before I knew it, I was on my way back home. Thank you Dr. Sirakos and San Antonio Endoscopy Center

The office staff is very nice and patient. I witnessed a few patients enter in and needed assistance with documents due to not being able to use the patient portal. The staff politely assisted and got them taken care of.

My husband is retired military. My prior colonoscopies were performed at military hospitals, but now that we are Medicare eligible, we must seek civilian care. I was referred to another physician at the Gastroenterology Clinic of San Antonio. However, when I visited the clinic's website, I saw the name of a female gastroenterologist, Dr. Allison Sirakos - I was delighted - who better, in my opinion, to understand a woman's body and the medical issues she faces. Dr. Sirakos and her team at the San Antonio Endoscopy Center were kind, respectful, efficient and thorough. The entire procedure was explained from the time I made my initial appointment until I underwent the colonoscopy. I would recommend Dr. Sirakos to anyone needing a colonoscopy.
