Dr. Frank Richard Crantz, MD

Dr. Crantz has been my Dr. for over 15 years. He has kept me alive so far. And I am thankful for that. I am surprised by some of the negative reviews I see here.

I went to Dr. Crantz during pregnancy (gestational diabetes) because the doctor my OB recommended was not available. I did not like him at all. I though he was very dismissive and not very personable. He did call personally to give test results but that was the only thing I liked about him. I dont feel like he gave complete information. After I delivered, I had some complications. I was released from the hospital and was to go see him immediately. When I got there, he saw me, didnt really look at me, read over my chart and told me to follow the plan that I was on because I was set to deliver soon. He didnt even notice that I had already had my baby. Which is odd because the doctors in the hospital communicated that to his office which is why he requested to see me. Everyone's experience is different. This is mine.

Extremely arrogant and unprofessional. I am an Asian descent, possibly even racist. Everyone beware of this doctor. He is not going to give the service of a professional doctor.

Dr. Crantz calls you personally to give you results from any test immediately. Explains everything even though I do not have a serious condition

Dr Crantz is an outstanding clinician. He is highly professional, patient-centered and very efficient. I was fortunate that I was referred to him 15 years ago and I remain a loyal patient. I trust him and value his expert clinical judgment.

I adore Dr. Crantz. After our first meeting I was nervous about returning because he basically called me out on my stuff. Every follow up appointment he has been kind and takes time to answer ALL of my questions. He calls you with lab results, not a nurse, and answers any questions about those results. He cares about his patients. Bottom line, if you're looking for a doctor to stroke your ego and not call you out on your poor health habits, he is not for you. If you want a brilliant doctor who will be a true partner in your care, go to Dr. Crantz. He is exactly what I needed and I'm healthier for staying with him.

Dr. Crantz continues to be a leader and innovator in endocrinology and internal medicine with his commitment to root cause analysis and continuing research/education. My personal thanks to him for his dedicated efforts to dive deep into the numbers and respective causal relationships to properly diagnosis issues and concerns.

The main thing you need from a specialist is accuracy and knowledge. Dr. Crantz has that in abundance. Highly recommend for anyone in need of superior endocrinology services.

I really appreciate the promptness of Dr Crantz and his staff. He's always on time and doesn't leave you waiting in the exam room after the technician has performed the initial workup. He also calls the next day with the results and any change of plan. Overall, I have been very pleased with the care I have received and have referred my patients to their practice.

Like Lt. Cdr. Spock from Vulcan, Dr. Crantz is all about logic -- it's all in the numbers of your blood work. That being said, it seems to be the trend these days with endocrinologists. Your T levels have a wide range of what is considered "normal" -- if you're right at the min or max fringe of that range, you're considered to be doing fine. But most of us with thyroid issues know that how you "feel" can be dramatically different if you are at the low or high end of the "normal" range. I will give Dr. Crantz credit for indulging me in wanting to try different thyroid medications and experiment with dosages until I found one that made me feel like "my normal" self (even though my T levels were always in the "medical normal" range. It can be a long process to find the brand and dosage that works for you, but it is worth it to wake up and feel like yourself everyday. All in all, Dr. Crantz is a good combination of the Vulcan science officer and the human; like Spock, he is both. At first he may baulk at your suggestions of changing your brand or dosage because "your numbers look good", but he always agrees to let you try. Because of this willingness on his part, I stick with him and feel very safe and confident being a patient in that very logical and pragmatic mind of his. Dr. Crantz, may you live long and prosper.

Dr. Crantz has a no nonsense approach approach which takes a few minutes to adapt to but he is one of the best in his field I have ever seen. I drive 100 miles each way to see him and have been with him for years. In all the years I've been seeing him I believe he's only been late one time which is incredible given the record of most doctors. The fact that he has his own lab, right on premises, saving me valuable time and money traveling to another location is unheard of. I don't know of another doctor that offers this. His office manager and staff have gone WAY beyond what is normally required in dealing with what has to be the worst insurance company on the planet. They and Dr. Crantz spent a lot of time, away from their busy schedule, to straighten out a mess created by the insurance company. As long as I'm physically able to travel I'll keep going to Dr. Crantz.

Always feel confident in the care of Dr. Crantz. He is knowledgeable and informative and I trust his suggestions regarding my health. I would highly recommend Dr. Crantz to my friends !

I have been a patient of Dr. Frank Crantz for about 25 years. He is a very caring and concerned physician who wants the very best for his patients. He is one of the few physicians who calls the patients himself to give them test results, etc. He is more than willing to try to answer patients questions and keep them informed of things that can improve their health. I have had very good results as a thyroid/diabetic patient from going to this physician. Although I moved to an area about 100 miles away from his office location, I continue to go to him for follow-up visits. I highly recommend him to someone who is looking for an excellent, caring and capable endocrinologist. His office staff is also always very friendly, capable and helpful. It always seems easy to make an appointment and they are very prompt in seeing patients on time.

I was fortunate to have been referred to Dr. Crantz following my retirement from the military. He quickly accurately diagnosed my condition and prescribed the proper course of treatment. I remain a patient 11 years later. He is patient-focused, in a direct and professional manner. I find his office to be highly-efficient and well-staffed - with labs and pharmacy refills managed effectively. He does an excellent job in keeping my general internist updated. I am grateful to be his patient and recommend his practice without reservation.

I've been a patient for at least 8 years, during which he has monitored and treated my thyroid condition, and determined when the thyroid needed to be removed. He seemed to have an uncanny ability to understand precisely when surgery was needed. I fully trust his knowledge and judgment, and have recommended him to many of my friends. I am very grateful that my physician recommended him.

Dr. Frank Crantz is my Endocrinologist. He made an early and correct diagnosis of my hyperparathyroidism and made an early appointment for me with a leading surgeon. I had a follow up for the surgery and test results and was highly pleased with the overall attention I received from Dr. Crantz. I cannot rate his bedside manner since he was not the syrgeon and it was outpatient surgery.

I consider myself fortunate to have an endocrinologist as skillful as Dr. Crantz. For the past twelve years I have been diagnosed with low thyroid, (Hashimoto's Disease) and high calcium levels following treatment for Non-Hodgkins Lymphoma. Dr. Crantz always takes the time to go over the many tests needed to follow my care. Each time I see him I feel confident that I am receiving the best medical care possible. I am never shy in questioning Dr, Crantz and his responses are thoughtful and directly on point to my concerns. I have frequently recommended Dr. Crantz to others needing an endocrinologist.

I appreciate the time he takes with his patients during appointments. There are not many doctors out there who are as thorough and will take this kind of time with their patients. He truly cares. On my last visit, I noticed that some of the office staff were new- the new receptionist was really nice and I had a wonderful lady draw blood (I have tricky veins, so to me, this is a big deal). I also appreciate that there is an in-house lab... many doctors' offices will send you to another floor/separate office for lab work which can slow things down.

Excellent fund of knowledge. Diagnosed my problem and explained it to me in terms I could understand.

i went Dr Crantz because another specialist was fairly confident based on my symptoms that I had thyroid issues. Well Dr Crantz barely listened to me, decided not to do blood tests and told me I was gaining weight ..despite working out everyday....because I was lazy. I was devastated and for the next six months was depressed as my symptoms kept getting worse my family convinced to go to another doctor, which I did. This doctor did blood tests that confirmed that I had hyperthyroid. Dr Crantz's callousness impacted my health, doctors like him are the reason people are skeptical of doctors. I would suggest never going t him especially for thyroid issues. My doctor at Georgetown said he was clearly not up to date on the latest findings related to women with thyroid issues.
