About Us

Patterson Schlotterer Medical Group formally DBA Armadillo Pediatrics and Currently Panda Pediatrics and Adolescent Care has been providing excellent primary medical care in south Phoenix for 23 years. Our name changed but, our goals and commitment to excellent medical care have not.

The decision to establish Panda Pediatrics in south Phoenix grew, out of our commitment to provide medical care to an underserved area. Our goal is to provide care to all pediatric and adolescent patients regardless of their ability to pay.

Panda Pediatrics is committed to providing preventative care to children and adolescents. Our goal is to provide highly personalized, best care practices, and treatments to all our patients. To end, we will maintain a highly trained, warm and caring staff. We are also committed to the American Academy of Pediatrics home model, which refers to the delivery of advanced primary care, with the goal of addressing and integrating high-quality health promotion, acute care, and chronic management in planned, coordinated, family-centered manner.

We are the home for the health care of your child.
