My name is Dr. Zach Ward, and I am excited to be coming back to the bay area after a few years away. I graduated from La Cañada High School in 2008, after which I received my Bachelor’s of Science degree from Brigham Young University in Economics. Toward the end of my time there, I discovered that I did not want a career in economics. A family friend invited me to his dental practice. I saw a few patients get new smiles, and I knew what I had to do. Four years later, I left the University of Connecticut School of Dental Medicine, D.M.D. degree in hand, and set out to make my way back to Southern California. Dental school provided me with many opportunities to learn and serve in the nearby community. I was privileged to serve as Class President all four years and was able to coordinate service opportunities for classmates throughout the area. While I felt prepared to treat patients upon graduating, I chose to train for an additional year in an Advanced Education in General Dentistry program at UCLA. This past year, I have been working at the UCLA clinic in Venice and gaining valuable experience in a variety of complex treatments, including endodontics, oral surgery, implant placement and restoration, full mouth rehabilitation, and occlusal management to help with chronic TMJ issues. This training has prepared me to serve you with the highest standard of dental care available to patients today. In my free time, I enjoy spending time with my wife, Kate, and our three children, Henry (5), Benjamin (3), and Grace (born May 2021). I am and always have been an avid Dodgers, Lakers, and UCLA fan (but will not hold it against anyone for being a Trojans fan). I am thrilled with the opportunity to be a part of this practice.
