What Our Patients Say About Us

Dr Pasternak was the first gastro who encouraged testing to properly diagnose my issues before trying to just treat my symptoms alone. He was very thorough, kind, and professional. His office is clean and efficient. Everything I had done in this office went smoothly. Because of him I now know exactly where to go from here. I thank him and his office for their efforts!

Not only is Dr. Pasternak awesome, but so is everyone who works there. The nurses are so nice and make you feel very comfortable, and everyone has a great sense of humor. After a procedure, Dr. Pasternak always asks if everyone was nice and if you were comfortable and gives you results right there. Very caring people.

Dr. Pasternak is the best doctor I've ever came across. Very thorough, professional, kind, considerate. Had to see him about 5 times in the last few months and every single time he took his time and explained everything. I never felt rushed. His whole staff is like that too. The nurses, the ladies at the reception area, the anesthesiologist... The whole office runs like a well oiled machine. I can only wish, all my doctors were like him and his practice.. Highly recommended.
