Endocrine Associates

This was my first visit, going in a recommendation from a friend. I did not have to wait long (my appt was at 12p), and all the staff I encountered were very friendly. I learned more from Dr Tanen in the 25 minutes total I spent there than all visits combined with my previous doctor. He listened. Asked questions. Most importantly his test and blood work were thorough. I mean really thorough. Now I have a comprehensive record of results to keep for personal records. He said test results would be back I a couple of days. And they were… and HE called me, not a nurse or PA.
The only «eh» moment was being told 24 hours before the appt that I did, in fact, need a referral. I asked, and it was not mentioned in the previous 2 conversations.
Granted, it’s the first visit, and we’ll see how they do over time. But I am happy we got got off to a good start!

I gave it five stars because I liked the place, the people and the doctors. Everyone was nice during my visit. My visit was on time. I saw Dr. Crantz. He listened and diagnosed me. He was very thorough. I have a follow up appointment set too. I don’t know why this place has two stars. I have seen worse doctors offices. tt’s in a nice easy location in Mclean. It was clean and even the people at the front desk were nice. Even in comparison to other doctors that I have been to in the area, I would go here for my internal and endocrinology needs. I think they would even be a great help to overweight people who can lose weight or have some medical issue for their weight.

I saw Dr. Rubenstein recently. Nice guy, competent, and thorough. But I would never come back to the practice because you always have to wait for something. I arrived to my appointment 15 minutes early and didn’t leave until 2 hours later. The appointment did not need to take that long.
I waited an hour before I was seen by the doctor. Why? Because there were 15 people in the waiting room before me. I have never waited that long at an office before. They clearly overbook their doctors there. Once I was seen by the doctor, the doctor kept transitioning me to different rooms and leaving for a few minutes after arriving at each room. I went from the waiting room to his office, from his office to the exam room, from the exam room to the sonogram room, from the sonogram room to his office, from his office to the lab room. I thought this was odd and it seemed as if he was rushing to see other patients in between each transition.
The other reason I will not come back is whenever you call the office, you are put on hold. Not 5 minutes, but more like 15 – 20 minute hold. The reason I had to call the office is because you are advised to call a week after your appointment to ask for your lab results. Once they are pulled, the doctor will call you back, or so I was told. I called three times to get my lab results and when I heard back from the office, a day later, the doctor was not the one giving me my lab results over the phone.

Over rated doctors and terrible staff, still dealing with the staff 1 year later after visiting. Avoid.

I like Dr. Tanen. I have reviewed him separately as an exceptional practitioner.

Doctors are good… their staff is not. It’s too bad and unfortunate. I know of some patients that look for other endocrinologists b/​c of their staff.

Dr. S. Mark Tanen is an awesome doctor! He listens, he is up on the latest issues with thyroids and he will try different methods. He is one of the best doctors I have ever been too. The front desk staff is terrible though.
