These swollen veins in the lower rectum or anus can lead to pain, itching, and in some cases, bleeding. Without appropriate treatment, hemorrhoids can progress into more severe health problems.

Always have a good experience with Dr. Johnson & his entire staff. They have diagnosed and kept me healthy for over 25 years.
The service was very quick staff very friendly.
Everyone was so nice. I was very very nervous and Everyone was nice and helpful in calming me down.
I had an endoscopy performed by Dr Guerra who is an awesome, caring Dr. I have been his patient many years. He always listens, and explains the questions I have. His staff for the endoscopy procedure was caring they took good care of me explaining everything, from the IV procedure, what they were gona do, to the actual endoscopy test. I had no reaction to any meds, or to the procedure itself. I very highly recommend Dr Ernesto Guerra.
Dr. Taheri was very informative. Continuous care when needed.
Professional caring I recommend it to all my family and friends
Everyone so nice Dr Ford is the best
This was the best possible experience. I was fortunate to be taken care of by the Stone Oak Clinic. It was world-class medical care, exemplary personalized care. I live several hours away and am confident the choice of using the SAGA practice was 100% the best possible care. The physician, anesthesiologist, nurse practitioner and office staff were the best I have experienced.
I owe my recovery to their excellence in both caring and competence. I will never go elsewhere. There are accommodating hotels nearby too.

Dr Guerra is very knowledgeable and explained everything perfectly. Staff is very kind and very professional
Dr. Alvarez is an excellent Dr and visit. I had seen another GI doctor for 6 months and was not diagnosed properly and prevented by the office from getting a second opinion. Dr. Alvarez knew what I had in 3 minutes no exaggeration. Treatment is not finished but vastly improved in 6 days with medication. Highly highly recommend seeing him for any GI reason!!
