Dr. Namita's Retirement and her message her patients:

"Having had a rewarding career in pediatrics, I will be retiring from private practice this month.  In the past thirteen years with TriValley Pediatrics I have had the opportunity to meet so many amazing families and be a part of a caring, incredible pediatric team.  It has been an honor to take care of your children. My relationships with you are dear to me and I will miss all of you." Namita Agarwal, M.D., FAAP

Same Day Appointment Policy
In an effort to make sure our patients can be seen promptly when needed, we are proud to offer same day clinic appointments. Scheduling same day appointments allows us the ability to see your child on the day it is needed for those unplanned illnesses, rather than having to wait for availability several days later. As always, we do continue to schedule annual well check visits up to 3 months in advance!

New Vaccine Policy In lieu of the recent and on-going Pertussis (whooping cough) and Measles outbreaks in our community, and in order to protect our vulnerable patients from exposure to these preventable highly contagious diseases, we will no longer accept any new patients who choose not to vaccinate their child(ren) against Pertussis (whooping cough) and Measles unless medically contraindicated.

New "No-Show and Forms" Policy and Charges Starting January 1, 2016 there will be new No-Show and Forms charges applied. Please click here for more details.

Allergy Drops are now available in our office Allergy Drops (Sublingual Immunotherapy-SLIT) are a safe alternative to allergy shots and can help improve symptoms of Nasal Allergy, Asthma, Eye Allergy, and Hay Fever. For more information click here.
