Welcome to Tri-CIty Pediatric Cardiology, P.C.

Tri-City Pediatric Cardiology P.C. is a premier medical practice offering cardiac care from fetus to young adults up to the age of 25 years. 

In our fully equipped offices in Johnson City and Kingsport we see children with heart murmurs, fast and irregular heart beats, chest pain, high blood pressure, cholesterol problems, congenital heart defects, and fainting.  We also assess cardiovascular fitness to participate in sports. 

We provide consultation services to all local hospitals.

We also are proud to serve two satellite clinics in Norton and Abingdon Virgina.

We strive to see all new patients within one week of their referrals.  If your doctor contacts our office because the concern is more Urgent we can make accommodations to see your child immediately. 

We encourage you to explore the website. 

Our Patient Resources section will provide your information on what to expect prior to your appointment and offers some helpful information and websites for our patients. 

Our Services and Specialties section will provide an explanation of the testing we offer.  

The trust and confidence you have in us is highly valued by all our providers:

Dr. Jerry Walkup,  Dr. Ashish Madhok, and Dr. Ashok Mehta.


We are happy to have Pediatric Nurse Practitioner Brooke Griffith join our practice.  Brooke will be seeing patients with our Doctors and helping to care for our wonderful patients.  We look forward to you meeting her during your visit.
