Pinnacle Endo - Dr. Anthony Jon

Meet Dr. John

Dr. Anthony John received his Bachelor of Science with a major in Zoology and a minor in Chemistry from Weber State University in Ogden, Utah.  He continued his education at Case Western Reserve University School of Dental Medicine in Cleveland, Ohio. Dr. John graduated as the top clinical rank in his class of 2002 and was awarded the HPSP Navy scholarship. He was then selected to complete an additional year of advanced education (AEGD residency) in general dentistry at the Navy’s largest dental clinic in Norfolk, Virginia.  

Following his residency, Dr. John proudly served as division officer onboard CVN-75 USS Harry S. Truman while deployed in the Persian Gulf during the Global War on Terrorism. After his tour was complete, he was selected for an advanced specialty residency in Endodontics at the National Naval Medical Center in Bethesda, Maryland.  He concurrently earned a Master of Science in Oral Biology from The George Washington University in Washington, D.C.

After his specialty training was complete, he was granted the privilege to serve with the Marines at Camp Pendleton and Miramar Marine Corps Air Station in our beautiful San Diego, California. During his tour in San Diego, Dr. John and his family fell in love with the warm weather and community of Scripps Ranch. He decided to stay in San Diego and established Pinnacle Endodontics in 2010.

In his spare time, Dr. John enjoys outdoor activities with his wife Jamie and their three children, Avery, Hunter and Colton. In 2017 they welcomed a Labradoodle, Wesley, to their family.

As a tooth specialist, Dr. John has been providing quality care for thousands of patients for more than a decade. Dr. John is a trusted endodontist in the San Diego community, passionate about saving teeth and looks forward to helping you!

OFFICE MANAGER

I joined Pinnacle Endodontics in November of 2022 and each day I get to help others. I have my studies in Administration and Management from National University in San Diego. With over 20 years working in the dental field, I have developed a strong sense of devotion to our patients and helping them understand their treatment and dental care needs. I truly enjoy every relationship we build with our patients!

Outside of work, I participate in my two girls sporting events in the Ramona Community. I love to hike, go for a nice run in the mountains, and play sports. I enjoy time with friends & family.

DENTAL ASSISTANT

Being the youngest of three children, I always had the worst teeth among my siblings, whether it be the most cavities or the most crooked teeth. This insecurity as a child eventually resulted in my fear of the dentist’s office until I met a dentist who took genuine interest in my well-being. Now that I have joined the Pinnacle Endodontics team, I hope to provide the same type of welcoming care for our patients! Although I was born and raised in Los Angeles, I decided to move to San Diego to continue my education and explore my passion in dentistry. I am currently pursuing a B.S in Biochemistry and hope to enter dental school in the near future. When I am not working or studying I love to cook and prepare new recipes for friends and family to try!

DENTAL ASSISTANT

In the summer of 2019, my interest for dentistry was sparked while volunteering on a humanitarian trip overseas. It was at mobile clinics that I found myself passionate about helping those who did not have access to dental care. I was intrigued by the entire world of dentistry and the more I learned, the more I was fascinated. I joined Pinnacle Endodontics in March of 2020 to help achieve my goal of giving back to the community around me while exploring my passion for dentistry. I am currently attending the University of California, San Diego and pursuing a bachelor’s in Human Biology with a minor in Global Health. In the future, I hope to attend dental school. In my free time, I enjoy exploring and finding the best food spots, going to concerts and music festivals, and finding new TV shows to watch!   Favorite Quote: “If we wait until we’re ready, we’ll be waiting for the rest of our lives.” ―Lemony Snicket

DENTAL ASSISTANT

Throughout my childhood, my teeth had their own unique story to tell. My underbite, in particular, often stood out as a distinct chapter. This personal chapter has instilled in me a profound understanding of the significance of thorough and empathetic dental care. I have experienced and learned firsthand that it is more than just looks, it is about ensuring that individuals feel confident and healthy. At Pinnacle Endodontics, I’m dedicated to extending that same level of care and understanding to each patient. Originally from San Francisco, I now call San Diego home, where I’m pursuing a degree in General Biology at the University of California, San Diego, with aspirations for dental school. In my free time, I enjoy going to the gym, tuning into sports on TV, and exploring Southern California’s diverse food scene.
