Jun 27, 2025All good
Jun 20, 2025Dr. Jonker and his staff are absolutely amazing. They treat you with the upmost respect and care. I would highly recommend their office to anybody.
Jun 5, 2025Dr. Yonker is great!
May 16, 2025My first encounter with Dr. Jonker was for an emergency appendectomy. He was the surgeon on that call that day and I’m so glad, as I later learned he was a bariatric surgeon. I wasn’t too familiar with bariatric surgery so when I went for my appendectomy follow-up, I was able to ask some questions and get to know him better. In our later meetings, Dr. Jonker proved to be very kind, compassionate, patient, and he had a great way of explaining things so that I could understand the process of how a SADI-S worked. I had absolutely zero qualms about having this surgery with him using a robot-assisted machine. My follow-up care has been exactly as expected - wonderful. I lost 81% of my excess weight using the SADI-S, which was his ultimate recommendation based on my presentation. I’ve maintained the loss for three years now following his guidelines and my health has corrected itself substantially (as proven by bloodwork). Perhaps the initial appendectomy was the best thing to happen to me, as the ultimate result of it completely changed my life. Thanks to Dr. Jonker I am finally enjoying living life! I couldn’t praise him enough for his skill and friendly bedside manner.
May 1, 2025I do not answer surveys so for me to even respond to this says a lot Look foward to seeing all again
