Dr Lynne Mielke and her team are the best! I always feel that I am getting the best care when I see Dr Mileke or on a phone apt. She is a very smart doctor who cares and looks out for you. She is a keeper! We need more doctors like her! The Staff and lab techs are excellent and they go out of their way to make your visit a good experience. And with the current shelter in place. They take all the precautions. Over all a very positive and clean environment. Thank you All!

Dr Mielke and her staff provide consistent high level of care- excellent diagnosis and treatment! My only concern is high level of cost. Seems that’s the situation with functional medicine these days.

Without hesitation I can recommend Dr Kreizenbeck if you are dealing with lyme disease. Her understanding of the disease process and treatment approach has been spot on and so far above what my allopathic MD was even able to understand. She is a great listener and respects my feelings about recommended treatments which I feel is very important since we all have an innate ability to be part of the treatment plan. I'd be lost without her!

I have never been successful at losing weight before but thanks to Dr. Mielke and her suggestion to start by reading the book "Any Way You Can, by Annette Bosworth" I was finally able to understand how sugar and carbs contribute to inflammation and disease and weight gain. I began the Keto diet and quite easily lost 35 pounds in 60 days as well as almost 4 inches off my waist and was never hungry. Who would have thought you could lose weight by eating steaks and salmon and salads and vegetables with butter and cream and avocado and olive oil and nuts and seeds. I loved how great the food tasted and never felt deprived. I feel so much healthier now and will never go back to eating carbs or junk food. Thank you Dr. Mielke for your support and encouragement.

I have been taking bio-identical hormones through Dr. Mielke for a little over a month and I am very pleased with the results. I feel I have my life back and that I’m my “old self” again after 3 years of suffering with hot flashes and sleepless nights. I highly recommend Dr. Mielke’s protocol to all those suffering in silence and being neglected by other medical professionals who diminish the dramatic reduction in quality of life which hot flashes and other menopausal symptoms cause. I am very fortunate to have found Optimal Health Spectrums and Dr Mielke.
