Patient Testimonials

Patrick C. - "Dr. Singh is amazing. Very smart and talented. I had 2 surgeries performed by him and had no issues. I am so glad that I had him on my side. I absolutely recommend him to anyone in need of his specialty."

the Tinnmann - "Dr. Singh is what I'd call a maverick among doctors…Nothing of what you'd expect when first meeting him…But make no mistake he is a knowledgeable & extremely skilled expert!…He was direct & to the point in his assessment & gave honest information about the causes of my hemorrhoids, the surgery that needed to be performed, & what was to be expected afterwards…I would not wish Hemorrhoidectomey surgery on my worst enemy, but should you ever find yourself in a position in life with Stage 3 or Stage 4 hemorrhoids which requires surgery… Dr. Singh is unequivocally with no doubt and undeniably the man you want to see!!! Side note: As much as it hurt at the time to laugh his office staff definitely helped ease the pain with the levity they brought to situation(thank you ladies)"

Walter M. - "Dr Singh and staff was very good. Had an issue with hemorrhoids and discussed the options, picked the right solution for me (surgery), and it worked out very well. The nurses, aesthetician and staff at the surgery center were all very good. The post post op instructions covered any issues I had. No complaints."

Arnold S. - "Hi everyone! I would just like to begin and say this is hands down the BEST experience I've ever had with any doctor. The staff is very friendly and just really awesome, it's as if I've known them for years. Dr. Singh is professional and very informative with his patients he will explain everything and anything you don't understand he will help you understand. This has been a very difficult time in my life and thanks to Dr. Singh and his staff who have helped me immensely, I have been able to get through my ordeal. If you need a colorectal Dr. I HIGHLY recommend Dr. Singh! You will not be disappointed and have the greatest care indefinitely. THANK YOU DR.

Gary D. - "Dr Singh came highly recommended by my primary physician and I could not be more pleased with Dr Singh and his staff. Dr Singh is talented, caring and totally committed to the welfare of his patients. The surgery was amazing and his care and concern following surgery has been wonderful. I would recommend him highly."

Richard M. - "I have had a severe urgency issue for many years. It changed my lifestyle as to when and where I could go. After my colonoscopy by Dr. Singh the issue continued with no physical reasons for it. I made a second appointment with the doctor to discuss my still existing problem. He took the time to listen and made 3 suggestions to try. After 1 month in the follow up appointment the issue were solved and I got my lifestyle back. Great doctor and great staff, ontime appointments and all 3 of his suggestion were with over the counter medications.. He is one of the rare doctors that cares and listens to the patient."

Dan M. - "Had an emergency ileostomy done on March 7, 2021. Because it was and emergency a trauma surgeon had performed the original ileostomy and I was given a colostomy bag until healed. It turned out I was to be revearsed out of the bag after 3 months. Unfortunately, the original surgeon would be out of country for 6 to 8 weeks for his vacation. I then knew I needed to find a new Gastrointestinal Doctor that could perform this second surgery. After several calls to many GI doctors it was only Dr Singh's office that were willing to help me. Not only was he very thorough, but very empathetic to my situation. I will be forever grateful to he and his staff. Thank you Dr. Singh."

Peyton W. - "Where do I begin? Dr. Singh is AMAZING. My husband developed an extensive perirectal abscess and after failed attempts with urgent care, the pain became overwhelming. Dr. Singh and his team got my husband in the SAME DAY within the hour as a NEW PATIENT because they didn't want him to go through the holiday weekend without treatment. When Dr. Singh took a look for himself, he decided it was too complicated for an in-office surgery and began calling hospitals to get my husband in for same day surgery. When one hospital didn't have OR time until 7pm, Dr. Singh looked further and found another hospital that could get my husband in for surgery within the next few hours. Dr. Singh performed my husband's surgery for a abscess that evolved into a fistula. Dr. Singh is highly competent, highly trained, informative and has great bedside manner. I would recommend him to any of my loved ones that have any colon or rectal needs. He took care of my husband without even knowing him prior and prevented him from possibly going septic over the weekend due to the extensive infection. The minute he walked into the room, I knew I could trust him with my husband's surgery. I could go on and on. So impressed with Dr. Singh and his team!!! THANK YOU THANK YOU!!!"
