It was forty years ago that I ventured out of New York City, New York with my new bride to southern California after having joined the United States Air Force as an officer, serving in the capacity as a dentist. While my time in the military was honorable and provided me with remarkable training, I only served for five years, leaving as a Major in the Air Force.

I graduated from Columbia University School of Dentistry in New York knowing that both my wife and I wanted to move west to a warmer climate. The United States Air Force provided me with the excellent opportunity to make this dream come true. When I left the Air Force, I joined a large dental practice in Riverside, California as an associate to the practice.

Then I went on to purchase my own dental practice in Santa Ana, California where I have remained until this very day, over thirty -three years. My wife and I have three grown children and seven grandchildren; we consider ourselves very blessed and spend as much time with our family as we can.

As for my career, I am an extremely fortunate man. I love being a dentist, and I believe my patients know this based on my commitment and devotion to them, their family members, and/or neighborhood friends. My ultimate goal is to offer quality dental work for affordable prices. Everyone who comes to our office can count on our honesty, our respect, and his or her thoughts and feelings being taken into consideration. I operate a smaller size dental practice that employs a staff of combined full time and part time employees some who have been with me for three decades and others who have been with me three to five years. Together we comprise a dental office that works hard to make sure that our patients leave happy and with a great smile.

Born, raised, and educated in southern California, I am the youngest of three siblings. Growing up, I always felt loved, supported, and encouraged to explore my talents and desires. My two older brothers set the bar high succeeding in their endeavors to become physicians, so I felt challenged to do the same striving to be the best I could be. I attended the University of California Santa Barbara and earned a Bachelor of Arts in psychology. Then I attended Chapman University in Orange, California where I earned a Master’s Degree in Marriage and Family Therapy (MFT). I continued onto a Post Baccalaureate Program at California State University Fullerton preparation for pre-med/pre-dental school attendance. I then applied to dental schools and was accepted to my number one choice the University of Southern California (USC). I graduated dental school and received my DDS in May of 2017. Being a dentist affords me the opportunity to make prompt changes in peoples lives whether it be to alleviate pain or suffering or to adjust their physical appearance in some regard. I find my occupation truly satisfying and pleasing. I found my professional calling in life saving the community at large as a dentist by providing the best dental health care I can. I love that I meet individuals from all different lifestyles and backgrounds young and older. My interactions with my patients mean a great deal to me because it helps me understand what I need to provide them with as a health care professional. I am married and the mother of three small children whom I love and adore. When I am not working I spend my time with my family going to the park, swimming, playing games, reading, traveling, and shopping. I am certified as a Invisalign Provider; I am a member of the California Dental Association, Academy of General Dentistry, Orange County Dental Society, and American Academy of Cosmetic Dentistry.
