I have the pleasure of being a patient of Dr. Holtorf for 13 years. I woke up one morning in 2004 unable to move without pain and so fatigued it was difficult to keep my eyes open. I went from doctor to doctor, specialist to specialist, spent 1 year in physical therapy to get my body moving again and I was still very ill unable to work or perform basic daily duties. After 3 years of seeing top of the line specialists that accepted my very good insurance plan, they had no answers for my condition other than fibromyalgia and no treatment plan which left me with little hope that I would ever function normal again. After days of research I set an appointment with Holtorf Medical Group. After numerous blood tests I was diagnosed with Chronic Lyme & Babesiosis. Because I had not been diagnosed & treated properly in the earlier stages by the Specialists prior to HMG my condition was now chronic and very difficult to treat but Dr. Holtorf was up the the task. We tried many treatments over the years, some worked, some didn't but I was grateful that Dr. Holtorf never gave up on me because today I can say my quality of life is much improved. Am I 100% no I am not and I probably never will be due to the Specialists that misdiagnosed me years ago. The nerve damage the Lyme bacteria has wreaked on my body will continue to be a challenge but I know when and if there are any new treatments to help my condition Dr. Holtorf will be right on top of it like he always is. I have never met a Dr. that does so much research and is knowledgeable of new treatment options for many conditions. Most HMG patients come here because they have been failed by their doctors. I read a review that said none of the Lyme patients get better, that is not true. I met some personally that did get better and were able to work again. It all depends on the individual and it takes time to heal years of damage. A few years ago, Dr. Holtorf was a lifesaver when I asked him to see my mother who had many specialists treating her for high blood pressure, thyroid & adrenal insufficiency. We had many trips to Urgent Care before she saw Dr. Holtorf. He adjusted her BP meds, Thyroid & Cortisol. Once he stabilized her meds her Primary & Endocrinologist Doctors followed his protocol and his treatment plan is still working for her today. After she suffered for months Dr. Holtorf had her fixed in one office visit. If you are very ill & need an expert to get down to the bottom of your medical issues and keep digging until you get answers, Holtorf Medical Group is the place for you. I have seen 3 doctors here and they are all excellent.

I found the Holtorf Medical Group (HMG) through a friend and we have never looked back. I was having multiple health issues with the short list of: major hormonal disruption, thyroid, chronic fatigue, fibromyalgia and a very bad hip. HMG ran the tests, put me on the proper medication and now I am feeling better than I have in years. They have helped me so much and my whole family and a ton of friends are patients there.

In addition to the great Docs, diagnostic equipment, and treatments, the office staff is nothing short of wonderful. The staff is kind, friendly and accommodating. They understand they are dealing with patients who have been everywhere to get help and are completely exhausted. Emily Montano, Karen Fitzpatrick and the rest of the staff are not only professional, they are a great comfort throughout the process. Dr. Holtorf is truly a treasure and my friends and family say the other docs in the practice have been great for them as well.

In addition to all this, they have a compounding pharmacy onsite. The staff and service are impeccable and most importantly fast and efficient.

We can’t say enough about our experience with HMG. Our entire family is grateful!

Dr. Holtorf was able to improve my thyroid condition even though I had already been treated for this condition for 20+ years. Dr. Holtorf was able to treat my under treated thyroid problem and I have never felt better. He is familiar with how my hormones interact with one another and was able to tell more about me medically than anyone else has. If I experience a problem that he is not familiar with, he actually conducts research and gets back to me with alternate ways to treat me. This man is a blessing, and I highly recommend him to anyone in the area or willing to fly to see him. I did – I live on the east coast but I flew in just to see him based upon other recommendations – it was totally worth it. I am now feeling like I haven’t felt since before my pregnancies in the 1970’s!

I am so grateful to Doctor Holtorf. I was feeling terrible, and had seen so any doctors, and no one seemed to be able to help me. THEN I found Dr. Holtorf. He took various tests, and then put me on hormone replacement with natural hormones, and I have never felt better.

From feeling that there was no tomorrow, to having so much energy and excitement...this has been my dream come true. I am so grateful to Dr. Holtorf and his wonderful staff.

After seeing 3 other doctors (over a 5 year period)for Hashimoto thyroid disease treatment, I finally found Dr. Holtorf (thank God!). I could write paragraphs on what I’d been through but the bottom line is that I finally found a doctor that is not only a good listener, compassionate & kind, but one who actually thinks “outside the box”.

For those of us who don’t respond in a conventional manner to medications, old school “by the book” endocrinologists have repeatedly patted us on the back & said, “Your TSH is fine”, just keep doing what you’re doing. In the meantime, I for one, was sleeping 16 hours a day, spent my life in a mind fog & was fatigued beyond belief (I even slept in my car during my lunch breaks at work).

Dr.Holtorf immediately asked the right questions, patiently waiting through my confusion & tears, and made changes to my medication regime that truly turned things around for me.

I can’t say enough good things about him as a doctor & a caring person.

Thank you Dr. Holtorf, you’re the best!!!!

I was a scholarship athlete, ran 4-miles a day 4 to 5 times per week for 30 yrs. Had run 3 successful businesses and was starting a new one. Then one morning I woke up and could barely move. I was so tired I could barely make it down the stairs. I was bedridden for about two months. This began a six year journey of 13 doctors. My symptoms were constant headaches, exhaustion, joint pain, no sleep literally two-three hrs per night with sleeping aids, panic attacks, constant anxiety, would explode at the drop of a hat, total body pain and burning, what seemed like inflamed skin, constant night sweats, bloating stomach, total constipation intestinal palsy if you will, eye pain, severe hearing sensitivity, total muscle atrophy and brain fog. I could go on but you get the picture. It was ruining my family I totally withdrew to my room for total isolation for 6 yrs when I wasn’t working.

The 12th doctor diagnosed me with Lyme disease, tried some treatments but really didn’t have an answer; he said it was beyond him. A typical syndrome of these types of illnesses is a obsessive/ compulsive desire to find out what is wrong. Every free moment I spent researching the web to find out what was wrong with me. My first doctor said I was depressed and just needed antidepressants. Between the first and 12th doctor I went through multiple treatments but all were shooting in the dark.

When the 12th doctor diagnosed me with Lyme and a toxoplamsa gondi infection, he gave me antibiotics and I began to have what is called a herxheimer reaction which created major symptom increase and crying attacks but he wasn’t giving me the right antibiotics long enough.

Finally, I found Dr Holtorf on the web and made an appointment. I almost started crying during the appointment because he was the first doctor that had a specific protocol and actually new what he was doing. He actually cared about me. He has treated me for Lyme, Epstein Barr, CMV, and Chlamydia pneumonia. He also has treated me for thyroid, hormone and for body degeneration. I am feeling the best I’ve felt in 6 yrs. I know I still have a ways to go but all I can say is thank God for Dr Holtorf, he has been a miracle to me and my family.
