"Friendly..efficient..professional are hallmarks of the office of Dr Shiva. He LISTENS which is lost art in the practice of medicine. He ACTS after getting the proper inputs. He follows up remembering YOU as a person and your medical profile. Very good interaction with this Doctor and office. The best thing is he makes every effort to make certain you understand whats happening In case without the being condescending. I recommend Dr Ratuapli to any one needing help with gastrointestinal issues."

"In the 35 years that I have been a professional public relations expert in the field of medicine, I have known and worked with more than a thousand physicians, and have been a personal patient of dozens of MDs and DOs. Mark Gulinson, MD, is easily among the top one percent. He is smart, intuitive, knowledgeable, skilled and empathetic. He both listens and communicates well. He cares a lot about his patients' welfare and makes the extra effort to ensure optimal outcomes."

"Dr. Tharalson is the epitome of a caring doctor. I was diagnosed with Lung Cancer this year and it was typed as lung cancer with a colonic/intestinal marker. Dr. Tharalson arranged for me to have an endoscopy and colonoscopy within 2 days. Two polyps were found with none being cancerous. I recommend Dr. Tharalson for his patient centric care."

"I, first, want to start out with the office staff. They are so kind. They found me an appointment w/o giving me a hard time. The appointment was the next week, not next month. Second, Dr. Gulinson is one of the nicest doctors I've seen in a good while. He was thorough with his exam and clear on his instructions. Third, the medication he prescribed for me was life changing. I was living with a stomach ache all day/all night. He fixed it with one pill and a different diet. 100%, I recommend him."

"As a teacher, I like to get my doctor’s visits completed during the breaks. When a slot was not available, Dr. Gulinson overheard my conversation with his office staff, and opened up a slot for me. As this was the first time I have done any such procedure, I really appreciated the time and care taken to make sure I knew what to expect. When I had a question about prep, it was Dr. Gulinson who called me back. An overall very good experience from beginning to end."

"Both my husband and I have been seeing Dr. Mark Gulinson for years, and we have found to to be absolutely wonderful, caring, and concerned. He has always spent as much time as we need with us. We love the fact that he is affiliated with a private facility for colonoscopy and endoscopy, rather than having to go to a dirty, germ-filled hospital, where you can pick up any kind of bacteria or disease. We would never choose anyone else! Thanks for everything, Dr. Gulinson!"
