Dr. Ader is kind, always greets you with a smile. He is very attentive and thorough and wants to make sure you are comfortable and understand your treatment options. Genuine concern for his patients. I would highly recommend to family and friends.

Dr. Ader has been my rheumatologist for about four years. I find him to be very thorough, professional and caring. I would highly recommend him to anyone looking for an excellent caregiver.

Dr Ader himself is okay . . . not great, but okay. I'd just to watch out for him to decide what he thinks your problem is and then doggedly stick to that diagnosis, no matter what you or any other doctors say or think. But it's his staff -- office and nursing -- where I finally drew the line. Dr Ader employs the most rude, uncaring, pretentious people you'd ever hope to not meet. As a customer and a patient, I'd rather deal with fast food workers at a drive up window.
The front desk receptionists are very rude. Talking about personal lives and apparently it's difficult to get back to the exam room on potluck day. Very disappointed in this unprofessional office and staff.
in Boise |
He was rushed during my appointments and did not finish his physical exam of palpating my painful spots. Gave me no solutions once I told him I did not want to use his drugs. The receptionist was so mean to me when I showed up 5 minutes late because I missed the wrong turn off on the freeway and she threatened to have to make me reschedule my appointment
