    I've gone to Dr Crantz for a few years. I find he understands my concerns and his most knowledgeable.

    Avoid this practice. I recently moved to Virginia, and called to enroll as a patient new to the…read morearea. I was told that before I can schedule an initial appointment, I need to "prove that I really have the condition" by sending recent lab test results. Is this how a doctor should treat anyone? Is it ethical? Is it legal?

    I saw Dr. Rubenstein recently. Nice guy, competent, and thorough. But I would never come back to…read morethe 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.

    So I am writing this in the exams room. This is my 3 rd visit with Dr Rubebstein. I came in for…read moretesting and he did an ultrasound and informed me that I had a nodule. Back for a follow up biopsy. FNA with ultrasound that hurt a lot. He must have stuck me 8 times. My neck has been sore for more then 2 weeks. I arrived at the apt today to get the biopsy results. I arrived at the Dr's office 45 min before my scheduled time and I waited an hour. I have now been in the exam room for 45 min with no Dr. I was the only one left in the waiting room. This is unsat! This literally should be a 5 min consult. I am a patient guy but this is definitely beyond the pale. As I finish this review, still no Dr.

    I am normally very happy with my doctors, but i can't stand Dr. Rubenstein. He has NO people…read moreskills whatsoever. There is always at least an hour wait and every time i see him he does tons of scans that take forever. One time he completely forgot i was waiting for an ultrasound and so i sat there FOREVER. its very frustrating. I also had a very bad experience with a biopsy. The first time i had one it was really painless and easy (done at at pathologist) and i knew my results in a matter of minutes. But when Dr. Rubenstein did it, i bled everywhere and had a huge bruise. PLus it took almost three weeks to get the results (which involved me going back in to the office and waiting an hour!) I have heard wonderful things about his partners but they wont let me switch within the practice.

She had an appointment scheduled weeks in advance, and at no point during the booking process were we informed of any outstanding balance. When she arrived, a front desk staff member named Camila refused to allow her to be seen until an old bill (over two years old) was paid in full. This was never communicated beforehand, despite my mother having been seen by this office multiple times since that bill was incurred. Turning away a patient at the door with no prior notice is not only unprofessional, it is a failure in basic patient care. If a balance was owed, the time to address it was when the appointment was being scheduled, not at the front door. Camila was disrespect beyond belief, she physically snatched my mother's cell phone from her hand to tell me what was owed. This kind of treatment is absolutely unacceptable. My mother is an elderly patient who came to this office in good faith to receive medical care she needed and was turned away like she was nobody. It is disgraceful, it is cold, and it reflects a complete lack of basic human decency. I would not recommend this practice to anyone.

From the first meeting I had with Dr. Possner, I knew things would be vastly different and that I had found someone that would have a profound impact on my health. My first appointment was the longest time I had ever spent with a doctor. My appointment was 2 hours and Dr. Possner had fully reviewed my medical records and engaged me in thoughtful conversation about my medical history. I left my initial appointment with a feeling of empowerment over my health that I had never really felt before. Little did I know that the impact of having Dr. Possner as my doctor would happen so quickly. I was on vacation and had an acute UTI. It was after business hours, but I was able to call the office and get the on call doctor that happen to be Dr. Possner. I walked him through my symptoms and he immediately called in a prescription for me. Because he had such knowledge of my history it was easy for us to communicate and talk through my symptoms. He checked on me via email through the client portal several times over the next couple of days to ensure I was ok. The fact that I was in a remote part of a different state and I was able to call and speak with the doctor saved me stress and the hassle of finding an urgent care to go to. He has made several recommendations to other specialists and doctors, all of whom have turned out to be amazing. His referral goes a long way with each specialist I have scheduled an appointment with. I can't recommend Dr. Possner enough; he's a great listener, thoughtful, caring, kind and you can tell he truly loves what he is doing. His follow through is simply amazing.
