The best of the best.... look no further. My mom has been a patient of Dr. Tieman's for years now, and the level the staff goes to help in any and all situations is above and beyond. Dr. Tieman is absolutely wonderful... from his overall knowledge to the caring of his patients. There is absolutely NO other doctor or staff that I would want my mothers care to be under. Thank you to all!!

Dr. Tieman is a remarkable human being and doctor, who has been my primary care physician for the better part of the last 20 years. Dr. Tieman has gone above and beyond for me more times than I can count. He is the most attentive, accessible, and compassionate doctor with an unparalleled bedside manner and human approach. Dr. Tieman will listen carefully to your concerns, taking detailed notes and then bend over backwards to help you find solutions to your health problems. Dr. Tieman is an open-minded, detail-oriented physician who thinks outside the box and is creative when it comes to solving problems. Dr. Tieman and his wonderful staff have helped me during some very difficult periods in my life and for that I'm truly grateful. The doctor and his staff are wonderful with absolutely everything I've ever needed, including: obtaining prior authorizations for medications and procedures, filling out various forms or paperwork including short-term disability claims, clearance forms for international travel, doctors' notes for sick leave to employers, yearly required employer physicals, pre-employment drug testing, on-site specimen collection, immunizations and flu shots, excellent record-keeping and provider referrals, and very fair financial policies for billing and payments. I've known Dr. Tieman and his staff for more than half my life, and I consider myself to be very lucky to have such a conscientious and reliable medical practitioner who I can call my primary care physician, and perhaps even my friend. Go Dr. Tieman and staff! Keep up the amazing work!

★★

Not certain why Dr. Powers was recommended for pain management when she refuses to assist in managing pain. Has caused massive pain attacks and unnecessary medical expenses due to being aggressively advised to go to the ER rather than listen to what a patient is telling her. Only rated as high as I did because literally everyone else was better.

The way I would like to start this review is unfortunately I am disabled. I have a lot of things wrong with me. And because I have all my health issues I have 4 other doctors I see And none of them could hold A candle to DOCTOR TIEMAN!!!. If it wasn't for DOCTOR TIEMAN I probably would not be Alive today. And I mean that!!!. When I have to go to my other doctors I wait in the waiting room forever. And then when I get to see the doctor it's only for about 5 minutes. DOCTOR TIEMAN is the most kind smartest doctor I ever met. When you have an appointment with DOCTOR TIEMAN he takes you in the office closes the door and it's just you and him. And he'll spend as much time with you as you need. You will not find a doctor like DOCTOR TIEMAN in this day and age like him. DOCTOR TIEMAN cares about his patients Alot. I feel like I can tell DOCTOR TIEMAN about all the problems I have in my life and he sits there and listens and you could tell that he really cares!!! IF YOU ARE LOOKING FOR A GREAT DOCTOR THEN DOCTOR TIEMAN IS THE MAN YOU NEED TO SEE!!!!. MY NAME IS STEVEN MANDERA AND EVERYTHING I JUST SAID ABOUT DOCTOR TIEMAN IS 100% TRUTH!!!!
