We have been done a lot of research on doctors in the Scottsdale, Phoenix, & Chandler area since we moved from Dallas TX. We are very pleased with this place!!! Awesome staff!!awesome medical assistants, awesome front desk!! and close to awesome hospital . Class A services and very diverse group of people ... our visit was on Jan 18 , 2016...... But their billing system is or something is wrong. My experience was I paid a co-pay andthwy said I did not have to pay but I paid anyway.....to go a bill 2weeks later saying I am late on a copay and went to collections. I paid it... either confuse me with my son or another Tony Brown but there are SSN to verify who you are dealing with...
