Dr.Thielemann is fabulous. He is patient, kind and treats you like you are important to him. He isn’t just rushing through to get you to the next patient. He CARES… and that’s not a quality you see very often in doctors anymore.

Dr. Thielemann listened to my concerns and outlined practical steps regarding my sleep Apnea hardware. He was professional, personable and easy to speak to. Should I have to return, I am sure that another visit will go just as well.

Dr Thielemann is an excellent doctor. After many years of seeing my original doctor who recently retired. I was worried about placing my care in the hand of a new doctor. Praise God, my first visit put my fears at rest! Dr Thielemann is a caring, personable, knowledgeable and professional doctor. He patiently entertained my questions as well as informed me step by step of his role involving my health journey. During my visit, he even voluntarily extended his openness in receiving and responding to call if I had questions, which is highly unusual. Unfortunately, I had to contact him early that following morning and sure enough, he immediately responded. I would highly recommend his care to any patient. As for the young lady who took my vitals, she was very professional and knowledgeable as well. She said she had been with Dr. Thielemann for many years and spoke highly of his work, friendliness and concern for his patients.

I saw this Dr Thielemann for my sleep issues and really appreciated how attentive and thorough he was. He took time to understand my symptoms, walked me through the possible causes, and gave practical next steps instead of rushing the visit. I left feeling reassured and confident about the plan.
