I waited 3 hours past my appointment time on the 1st visit. He was so late to the surgery center that the were about to reschedule my procedure. The follow up visit i waited 1.5 hours past my appointment time and just left. I was informed that 3 to 4 hours is NORMAL for this office. They also refused to give me my medical records, I have had to get them ordered through my regular physician.

Terrible appointment managing. Left after waiting over 2.5 hours. So rude!!!

I have had Dr. Klin since he first moved here and he has been a wonder. He is very knowlegable about a lot of medical situations. He makes the patient comfortable. He is very interested in each patience and takes the time to listen. He has cured me of several organisms and sees to my future health. He is great.

Been a pt 3yrs now, he is far the best doctor I've ever met, he is extremely intelligent, compassionate, & a truly outstanding doctor. The wait is longer than expected, but I count myself truly lucky to have found this amazing gastroenterologist. The staff accommodated me the best way possible & are extremely empathetic, sincere, and always smiling, which can truly better the atmosphere of an office. He will go over & beyond to find the problem & a treatment plan. I would highly recommend!

i had the pleasure of meeting Dr Klin with my mother. She was having difficulty swallowing and was choking on most all her foods. The office staff was vert accommodating and caring. Once we were in the office things seemed to move very fast. Once she was seen she was admitted to the hospital and he saw her that evening and then again in the morning and a procedure was done after an hour. After his promptness I have since changed from the gastro doctor I was seeing to Dr Klin. Highly Reccommend

Dr Klin was on call when I came to the emergency room with a fish bone in my throat/esophagus. Dr Klin was called and I was prepped for the procedure. I had completed all the forms, been administered to by the nurses/and other paraprofessionals, had a CT scan which confirmed the presence and position of the bone, was in a gown and laying on the table when Dr Klin informed the staff he wasn't showing up. He forced me to go elsewhere and spend a night beset with discomfort. Disgraceful.

Waited over 2 hours just to be called in for prep, the entire procedure took over 5 hours and the doctor never talked to my family or me, the patient, afterwards. We had no knowledge of the results until I called his office. He was rude--just before the procedure, not even introducing himself to me as I had seen his PA in the office. If I had not seen his advertisement on TV, I wouldn't have known who he was. This kind of treatment is unconscionable.

Disgusting wait time!!!!!!!!!!!!!!!!!!
Panama City, FL |
Dr. Klin is a very busy specialist. I generally have a wait time for my appointments, but he is definitely worth it (and I've come to expect a wait at most good physicians offices). The staff is accommodating and even offered me fresh coffee and crackers! I'm feeling much better after seeing Dr. Klin and I would highly recommend him to anybody having stomach issues.

I feel he is not trustworthy in that he is reckles. He punctured my wife's bowels during a colon oscopy and would take no responsibility.

Dr Klin treated my husband last March / April and disgnosed a rare condituon. He recommended that we go to UAB in AL for further consultation and treatment. My husband was diagnosed with a rare cancer in May. He started chemo at Sacred Heart Oncology in Santa Rosa for 7 months and UAB Doctors successfully completed the whipple and removed the tumor in February 2016. We are extremely thankful for Dr Klin's expertise snd recommendation. He saved my husband's life.

Absolutely terrible. Wait times are rediculous. Usually wait 3 hrs for an appointment. Then he doesn't care what you have to say and will clean out your insurance. He was over an hour late for surgery and and prescribed me some meds I was elergic too. My pharmacist caught his error and it would of killed me. Do yourself a favor and find a good doctor.
Too many clients. Scheduled a medical test with him and waited for 3 plus hours before starting. No consideration for other people or their time. Say him for less than 10 minutes at the office meeting. He never read my medical chart, was rude and uninterested in my true symptoms. Had no problem writing scripts though. If he is a good doctor, I would never know. His waiting room was a cattle stall.
