Our Pediatricians will collaborate with a Specialty Provider and make an appropriate referral if your child needs care beyond the Pediatrician’s expertise.  Please contact us prior to seeing a Specialty Provider. Always call us first before going to urgent care or ER unless the situation is life threatening.
