"Dr Joseph was very helpful in explaining my meds to me. He told me how they worked and why I should take them as he prescribed. Very considerate and easy to get along with! I would recommend to everyone.."
"Dr Joe Johnson has been my GI Dr for many years would not change for anything. Caring good listener only makes decisions that are better for you and not any companies or individuals just what’s best for you."
"I feel very satisfied with the way they treated me and gave me answers all my questions. Cynthia Guzman ,NP, was very kind and answered all my questions very professionally. Thank 😊 🙏"
"Dr. Joseph E. Johnson IV and his staff did an excellent job. However, the intake nurse didn't know how to do a proper IV. It took 7 times before the IV was finally in my arm. Then it was so painful, I could hardly stand it. This left bruises on my arm and hand. The anesthesiologist with Dr. Johnson in the procedure room was kind enough to redo the IV and he did an excellent job. After that everything went well. They even checked up on me the next day to see how I was doing. If you need to have a colonoscopy I highly recommend Dr. Johnson."
"Hadn’t seen doctor in a couple of years but he knew my background (tests) and brought me up to date on what my next steps were. Felt confident I made right choice in returning."
"Highly recommended Doctor Johnson His office called and said it's been 10 years Since last colonoscopy! Office Erica got me scheduled. She worked with my insurance to get everything covered. The prep drink that they use now is so much better than what they used to use. Had the procedure. And was home in 3 hours. Very nice people in office, in pre-surgery, and post surgery. 👍👍"
"A Smooth Experience with Professional Care at San Antonio Gastroenterology Associates From the moment I arrived at my doctor's office for my colonoscopy, I was greeted by a team of individuals whose professionalism shone brightly. The check-in process was not only smooth but also reassuring, setting a calm tone for the procedure ahead. Each staff member I encountered displayed a commendable work ethic, ensuring that every step of the process ran like clockwork. Their efficiency and kindness did not go unnoticed, and it was these qualities that left a lasting impression on me. I am genuinely impressed by the office team's level of care and attention to detail. It's clear that patient comfort and satisfaction are their top priorities, and they deserve high praise. Thank you Mr. Joseph E. Johnson IV, M. D. Sincerely, Isaac A. Richards"
"I LIKE TO THANK ALL OF YOUR STAFF FROM YOUR From the representative in the front area to the nurses in the back will assess me and the anesthesiand it and everybody that did a great job. I'd like to thank him very much and I feel way better. And my procedure went great and I am very blessed that you Mr. Doctor Johnson have so much wonderful staff. Thank you and have a blessed day."
"The staff was very nice. Love Dr Joseph very pleasant made my visit stress free everything went great. Really loved the warm blankets they put on the patients."
"Well making appointments could be easier. The phone system leaves a lot to be desired. I was happy Dr Johnson saw me personally. PAs are helpful but I asked for help 4 months ago. Still struggling with a cranky gut. The MIRALAX worked at first but then I had the total runs for 3 days. Now total constipation. I'm glad to be reassured I don't have cancer but if I die from a reaction to med. I'm just as dead. See you on Tues. And maybe we can figure out how I can poop and have pain relief. Be nice if it could happen."
"Dr Johnson has consistently been great doctor ever since I’ve known him. I’ve referred my patients to him for decades and he took care of them well. And since I won’t refer to someone unless i’d go.to them myself, i and my family also are under his care. Thank you for taking care of all of us Dr Johnson!"
"Dr. Johnson and his staff are kind, professional and caring. He took a great deal of time with my husband who is battling NHL to help him understand how his bowels are reacting to his treatments and what is the best plan."
"I was taken into a room soon after signing in for my procedure and treated by a kind and caring staff who explained very well details of the procedure. After saying I understood, I was soon put on a rolling clean bed and taken to a pre preparation room where my vitals and an IV was put in. The outstanding staff of nurses explained the procedure again to me.. Then after undressing and putting on the procedure gowns I was taken to the procedure room to be sedated. Then Dr. Johnson came in to re assure me that I will be fine and told me what he was going to do. Then the sedative Dr. put me to sleep and all I remember is the nurse waking me up after the colonoscopy procedure was done and rolled me on the bed back to the pre procedure room. Gave me and my wife a very well procedure report and some details of what Dr. Johnson found and did. And instructed me when I was to return for a follow up appointment with Dr. Johnson. Then after getting dressed I was kindly wheelchair led to the entrance where we awaited for my wife to bring our car around to pick me up. Then at my follow up appointment Dr. Johnson was kind and courteous and professional in explaining his findings and the results of lab tests and gave me some good advise on how to keep from getting cancer. I find that they all treated me with caring, compassionate and professional medical care. And I have no ill effect after the procedure. Thank you Dr. Johnson and your entire staff for your courtesy and professional treatment."

Thank you Dr. Johnson. Cynthia Guzman too, our NP at SA Gastro, is great and so patient listening to my many questions and concerns over the past year helping me a lot figuring this out! Thank you Ms. Guzman! I want to recognize too, Harley, Medical Assistant to Dr. Johnson and Cynthia Guzman, who is so nice, helpful and patient at every visit and always returns my calls when I have additional concerns or questions. Thank you Harley! Want to also thank Dr. Johnson's Receptionist at his Sonterro office, Monce, for helping us over 2 days after my last office visit, to find my wife's cell phone that she accidentally left in the building. Monce cared enough to make some calls and helping us ultimately meet up with the Building Maid (thank you!), who was trying to find us too. What a Blessing! Thank you Monce! Thank you ALL at San Antonio Gastroenterology Sonterra Blvd for your care, niceness and patience over this last year and my continuing care for peace of mind all is good."

I’ll have to have a colonoscopy since I have a strong family history it, but I trust that if anything does come up Dr. Johnson will be there to take care of me with his medical expertise."
"I recently had a colonoscopy done but experienced a hard time with the information sent regarding my instructions that were needed to be followed prior to the procedure. The email I received had four icons to review and get my instructions. I went through these handouts and found they were mostly about other types of types of diseases one could encounter. Others had pictures about drs and staff of other offices like the one in San Antonio. Finally at the end it asked for me to join the different from a group of social networks that I don't see fit to join Never got the procedure to follow prior to my procedure."

He is a friendly and warm professional who I would just as soon recommend to you as I would have at my dinner table. Thank you Dr. Johnson for being the doctor we all need!"

The nurse called me back on time at 5:30am, and spoke with the anesthesiologist and doctor shortly after. I was all done, and released to my bride by 8:00am and on my way home. Other than being a little sleepy, I felt fine! This is a fantastic, friendly, and professional team!"

"I was having some serious"heartburn" so went to my primary care physician who had me take some actions to reduce the problem. Continued symptoms prompted my primary care to order an Endoscopy with my previous Gastroenterologist but they couldn't schedule me for two months. My PCP said he would schedule one with Dr. Johnson, who he frequently recommends. Dr. Johnson was able to work me in the following week. The entire process with Dr. Johnson and his staff was great; friendly staff on the phone and in person. Dr. Johnson was very informative and friendly. I was very impressed with the entire process with Dr. Johnson."
