Dr. JJ Koval

Founding Dentist

Doctor of Dental Surgery (DDS)

Dr. JJ Koval is a patient-centered dentist who loves asking the question: "how would I care for this person as I would care for myself?" He is committed to relational connection and the pursuit of clinical excellence on behalf of those he serves. He is passionate about providing personalized dental education and treatment options to his patients so they can make informed decisions as advocates of their own dental health.


Dr. JJ grew up in Camarillo, CA, before moving north to attend Stanford University where he majored in Human Biology and captained the men's soccer team. After graduating, he had a 3-year career in professional soccer playing for the San Jose Earthquakes in Major League Soccer and Sacramento Republic in the United Soccer League.


When Dr. JJ decided to return to his passion for healthcare, he closed the chapter on his soccer career and moved to Omaha, Nebraska, where he completed his dental education at Creighton University, finishing Top 10 in his class. In order to invest further in his clinical skillset, Dr. JJ completed a postdoctoral advanced education in general dentistry (AEGD) at the Tibor Rubin VA Medical Center in Long Beach, where he served our local veterans. There he provided dental care in a variety of disciplines including general dentistry, dental surgery, surgical implant placement and restoration, prosthodontics, periodontics, removable dentures, and 3D cone beam dental imaging. Before starting New Garden Dental, Dr. JJ has been practicing as an associate dentist in Newport Beach.


Dr. JJ is married to his wonderful wife, Karli, who works as a PA for a functional women’s health practice in Irvine as well as doing the social media and marketing for NGD! They have a sweet son, Brooks. Dr. JJ loves being an active part of his local church, spending time with family in California and Texas, and being outside, including hiking, water skiing, soccer, pickle ball, spikeball, and watching just about any sporting event.
