Dr. Sean Thompson
Dr. Sean Thompson has a simple motto that guides everything he does: treat others how you would like to be treated. For over two decades, he's stayed true to that principle with every patient who walks through the door, providing the kind of genuine, compassionate care he'd want for his own family.
Education and Clinical Excellence
A graduate of the world-renowned Herman Ostrow School of Dentistry at the University of Southern California, Dr. Sean earned his Doctorate in Dental Surgery with high honors, ranking at the top of his clinical practice class. His commitment to excellence didn't stop after graduation. He's completed extensive continuing education in implantology through the Las Vegas Implant Institute, advanced cosmetic dentistry, oral conscious sedation, TMJ therapy, and laser dentistry, constantly expanding his skills to offer patients the most current, effective treatments available.
Professional Credentials and Expertise
Dr. Sean maintains active memberships in several prestigious dental organizations, including the American Board of Cosmetic Dentistry, the American Board of Family Dentistry, the World Clinical Laser Association, and the Dental Organization for Conscious Sedation. This ongoing involvement keeps him at the forefront of dental innovation and allows him to provide state-of-the-art care using the latest techniques and technology.
Military Service and Leadership
Before establishing his practice in Southern California, Dr. Sean served six years in the United States Army Dental Corps, where he received the Meritorious Service Medal for his dedication and expertise. His military experience laid the groundwork for his clinical skills and deepened his commitment to patient safety. He later shared this knowledge by lecturing at international seminars on sterilization techniques and patient safety protocols.
A Legacy of Service in South Orange County
Since 2000, Dr. Sean has been serving families throughout South Orange County, from Laguna Niguel and Aliso Viejo to Dana Point, Mission Viejo, and San Clemente. Some patients have trusted him with their smiles for over 20 years, a testament to the relationships he builds and the quality of care he provides. Now, as a father-son practice with Dr. Zachary joining the team, that legacy of compassionate, skilled dentistry continues into the next generation.
Life Beyond Dentistry
When he's not in the office, Dr. Sean enjoys flying, surfing, and spending time with his wife Lisa, their children Kory, Zach, and Nicole, and his grandchildren Sophie, Peyton, and Winter. You might even catch him playing drums at his local church, bringing the same energy and dedication to music that he brings to dentistry.
Dr. Zachary Thompson
Dr. Zachary Thompson brings both technical precision and genuine compassion to every patient interaction at Thompson Dental. A Southern California native, he grew up watching his father, Dr. Sean Thompson, help patients overcome dental anxiety and restore their smiles, inspiring Dr. Zachary to follow in his footsteps.
A Comprehensive Path Through Dentistry
Dr. Zachary's journey has been thorough and hands-on. He began as a dental assistant in 2015, earning firsthand experience in patient care and clinical operations. In 2016, he became a registered dental hygienist after earning his Bachelor of Science in Dental Hygiene from West Coast University, spending years building relationships with patients and understanding their concerns from the hygiene chair. This foundation gave him unique insight into the patient experience before he earned his Doctor of Dental Surgery degree from the Herman Ostrow School of Dentistry at the University of Southern California in 2023.
Transforming Dental Anxiety into Trust
What drives Dr. Zachary most is transforming negative dental experiences into positive ones. He understands that many patients carry dental anxiety or past trauma, and he considers it an honor to help them feel safe, comfortable, and cared for. His calm demeanor, patience, and attention to detail help even the most anxious patients feel at ease.
Beyond the Dental Chair
Outside the practice, Dr. Zachary maintains the same level of dedication and discipline he brings to dentistry. An ultramarathon runner, he has completed 100-mile races through some of the most challenging terrain. He's also an avid surfer, weightlifter, and outdoor enthusiast who loves camping and spending time in the mountains. In a unique blend of athleticism and creativity, Dr. Zachary has authored a book titled What the Enemy Meant for Evil, that was released in early 2026.
Thompson Dental is an exceptional dentist office. Dr. Sean and his son, Dr. Zachary are so calm, friendly and knowledgeable. They put you at ease immediately. You know that you are in good hands. Sandy, the office manager, is so kind and helpful and works with you to make your appointment go smoothly. All of the office staff greets you with a smile and asks how you are doing. All of the dental work, a bridge, an implant and new crowns across the front of my mouth have given me the confidence to smile and not cover my mouth. They simply are life changing dentists.
