Frank R Crantz, MD

Terrible experience. He needs to work on his bed side manner. He has no social skills and lacks compassion. I felt disrespected and not listened to when I saw him. He was condescending and I got the sense he wanted to tell me what to do, instead of work with me collaboratively (since you know it IS my health and body). There was a mix up about what he could and could not help with and instead of explaining it to me in a calm and civil manner, he raised his voice and was very condescending. I had to walk out I felt so belittled. Someone else on here said he should retire, and I agree. If you want to see someone that treat you with respect, is compassionate and acknowledges your autonomy, don’t see this guy.

DR Crantz is technically the best endocronogyst in northern virginia. You dont have to wait for a week to get your test result. Super efficient in the United States！Love my experience so far！

I went to see him for rapid bone loss, and had just before that learned that I had low thyroid production. I didn’t like him at all. He really didn’t take my concerns seriously and I thought he was arrogant. Told me to do jumping jacks.
I actually reversed the bone loss after another doctor increased my thyroid meds. That took several years, but in in my case insufficient thyroid hormones cause rapid bone loss.

Dr. Crantz needs to retire.
I drive from Leesburg to Mclean to see my specialist and spend $ 30 to spend less than 5 minutes with him. Literally, every appointment has consisted of him speaking to me for probably 2 – 3 minutes, his staff taking my blood to check for hormone levels, and adjusting my prescription. That’s it. I voiced my concerns about my prescription’s side effects, and he brushed them off. He never sent me to get a sonogram of my thyroid to check for cancer, which for my disease, there runs a possibility of cancer, which can creep up in a person’s 20s and 40s (I’m 27, and actually found out about this from my gynecologist). I would ask questions, he would answer them abruptly and dismiss my questions regarding alternate therapies. You can tell this guy does not love his job. And last but not least, his staff is by far some of the rudest employees I’ve ever encountered. I will call into the office to speak to a staff member, they will put me on hold, and never pick back up again. I have to call back again and again if I want to actually be able to speak to someone! No one EVER smiles in that place, I don’t even think I’ve ever heard «Have a nice day!». Granted, I’m sure their working conditions aren’t the greatest.
I’ve already switched doctors, but I wanted everyone to know not to waste their specialist co-​pay for this guy if you want real healthcare.

Not bad, not bad.
After dealing with the wholly inept VA system for the last 18 months, I finally said that enough was enough and I wanted to see a civilian specialist. I went in to have my thyroid checked (a wonderful by-​product of my first Afghanistan deployment) and potentially adjust my dosage levels. He listened — somewhat eccentrically — to me describing the situation and then detailed his treatment strategy that he was going to go through. It jived with my internet research on the subject so I went with it.
My only complaint was this overweight Persian woman who insisted on yelling into her phone for 30 minutes while we were in the waiting room. The nurses did nothing about it and right when I hit my breaking point and was about to say something did she go back for her appointment. It makes me want to go buy the cell-​phone jammer and keep it on me for such occasions. Even if they are illegal.
I’ll go back — better than what I can say about the VA!
