As a licensed healthcare provider specialized in pediatrics myself, I can honestly say that Dr. Kanagal is one of the best Pediatricians in the Scottsdale area. Scottsdale Children's group has multiple locations and takes almost all insurances. Their referral coordinator, staff, and manager are all also very helpful.
The reason for 4 out of 5 stars however is because their Nurse Practitioner at the Osborne location was very poor in her physical assessment skills and could have done significant harm to my child based on her plan of care.
I would highly recommend against seeing the nurse practitioner at Scottsdale Children's Group, but have nothing bad to say about the staff or doctors there. You can almost always get same day appointments, and the physicians are superior to the numerous doctors I have met in my personal and professional life.
*UPDATE* (7/20/2017): I have been meaning to write this for awhile. I no longer recommend Dr. Namjoshi. I am very sorry to write this but his recent actions and demeanor leads me to believe he does not truly care and love his patients like I had once thought he did.. Very disappointing, I thought there were more genuine doctors out there
