Was extremely rude and short with me both times I have met with him. I am 22 years old with awful abdominal issues and just want to get to the bottom of what's wrong with me. Even after my endoscopy he could not give me or my mother more than 2 minutes of his time to answer some simple questions of mine that would've given me so much peace of mind. I have never been so disappointed with a healthcare professional.
Dr Dale after some testing scheduled me for an endoscopy , a procedure that I never had before and which I was apprehensive about. My husband had the procedure with a different doctor and had told me a horror story. Dr Dale was wonderful, understanding and more than willing to answer my questions, acknowledge but quell my fears. It was quick, painless. He has a very reassuring bedside manner and patience with chicken patients like myself.
Great personality Patient with explanations in answer to any questions
Very dismissive. Totally lacking in people skills. Does not return phone calls or follow up . Received adequate care, however would not return to this practitioner. Does not like to answer questions. Office needs a total enema. There are other doctors just as qualified to take my money. Not impressed.
He's very helpful and will try to keep you off meds. I've have multiple colonoscopies and endoscopies with him and never had a problem. His team is always helpful and courteous. Very busy at all the offices, so hard to reschedule, but they work hard to get you in.
Dr. Sun was friendly, courteous and professional. Highly recommend him to anyone in need of a Gastroenterologist.
Dr. Heisig is smart , to the point , and confident .
First let me just say, Dr. Koh is an excellent physician! I had seen my GP for over a year for my problem and was put through all kinds of tests. Each test returned a normal reading. I finally asked for a referral to Dr. Koh and within a month, I had a diagnosis and was setup with the an appropriate treatment plan. Other reviewers have commented about D. Koh being insensitive etc... but he is NOT! He is a very professional Dr and is there to diagnose and treat you, not be your best friend.
I rate John Sun poorly for three reasons. First, he has no bedside manner at all. He has been not just curt, but impolite. Second, with a problem for nearly a year, it has been only possible to get three appointments for diagnosis. For one of those, his office failed to schedule. His offer to have me wait an extra two hours cost me the entire afternoon. Third, apparently owns his endoscopy facility, thus profiting from my prescription in two ways. I believe that is a conflict of interest.
If you plan on traveling and have Dr. Edison please be aware that he will not be able to provide you any guidance while you are away. Some unpredicted events happened to my while she was visiting me out of state and Dr. Edison would not provide any input on path forward to get her home. It's just sad when doctors have no compassion or dedication to their patients.
Dr. Sun is very personable and reassuring. I would recommend him to anyone who needs a GI dr.
Kind, attentive and personable. No reason at all not to consider Dr. Sun if you need gastroent.... ok stomach related care.
Dr Heisig on both occasions was arrogant, dismissive, physically squeezed my shoulder while I was in wheelchair, finger pointed that I was responsible, threatened to and did release me from his practice after I wrote a complaint letter about one of nurses that gave me incorrect information for prepping, Dr Heisig threatened me while my husband was in the room, as I wanted to know what grounds he had to refuse service and he would not explain. He is a bully,and doesn't like us asking questions.
Don't care for this doctor's bedside manner. I felt he was ordering me to have unnecessary tests that I didn't need or want. I my opinion he was rather pushy and condescending.
I will tell others family members and friends he is a awesome doctor he always get to the bottom of any problem.
