I've rarely had a doctor as attentive and interested in my welfare as Dr. Oertel. He listened, took my concerns seriously, and helped me to clearly understand my health issues. I highly recommend him.

It was the first time I met with him or anyone in his department. I found his information useful, he was professional, I appreciated being able to meet with someone who had thorough knowledge of diabetes. He provided me with sample med and a test kit. I had a good experience with him.

Dr Oertel is an outstanding endocrinologist, one of the very best physicians I have ever seen or interacted with. He is thoughtful, caring, and knowledgeable. He takes the entirety of the patient's health into account, and carefully and clearly makes his recommendations. I give Dr Oertel and his team of nurses and assistants my highest recommendation. We are so fortunate to have an endocrinologist of his caliber in Lawrence.

Excellent! Due to a recent COVID-19 exposure my appointment was switched to tele-medicine. That change was made quickly and smoothly.

Dr Oertel seems to be very attentive to concerns most of the time. I did ask for a test to be done that he dies t usually do, and upon the third request w a better reason why I wanted it, he ordered the lab. I was very appreciative. Waiting for my results.
