Your Family Dentist in Simi Valley
More Than 25 Years of Experience
With more than 25 years of experience in dentistry, Dr. Kosta brings a unique combination of clinical expertise, a gentle approach, and a genuine passion for caring for his patients. He believes that great dental care begins with listening, understanding each patient’s individual needs, and taking the time to explain treatment options so patients can make informed decisions about their oral health.
Dr. Kosta provides comprehensive care under one roof — from preventive and general dentistry to restorative procedures and dental implants — so families can receive the care they need without being sent elsewhere.
A Journey Built on Dedication and Experience
Dr. Kosta earned his dental degree in 1998 from the prestigious National and Kapodistrian University of Athens School of Dentistry in Greece. His professional journey also included serving as an officer and dentist in the Greek Army’s elite Green Berets, an experience that reinforced the importance of discipline, responsibility, and service to others.
After moving to the United States, he obtained his California dental license in 2003 and began practicing dentistry in Agoura Hills. In November 2007, he achieved his goal of opening his own dental practice in Simi Valley, where he has been proudly caring for individuals and families ever since.
A Different Kind of Dental Experience
Dr. Kosta understands that visiting the dentist isn’t everyone’s favorite activity. That’s why he makes it a priority to create an environment where patients feel welcomed, heard, and never rushed.
Known for his calm demeanor, gentle touch, and willingness to explain every step of treatment, he takes particular pride in helping patients who may feel nervous or anxious about dental visits. Whether it’s a routine checkup, restoring a damaged tooth, or discussing more complex treatment options, his philosophy remains the same: treat every patient with the same care, honesty, and respect he would want for his own family.
He believes in helping patients understand not just what treatment is recommended, but why it may be beneficial. His goal is to provide thoughtful, personalized care that supports long-term oral health rather than simply addressing immediate concerns.
Proud to Call Simi Valley Home
Since opening his practice in 2007, Dr. Kosta has had the privilege of developing lasting relationships with his patients and their families. Some have trusted him with their dental care for nearly two decades, and seeing familiar faces return year after year is one of the most rewarding parts of his profession.
Together with his dedicated dental team, Dr. Kosta strives to make every visit a positive experience, combining modern dentistry with the personal attention and familiarity of a neighborhood practice.
Beyond the Dental Chair
When he’s not caring for patients, Dr. Kosta enjoys spending time outdoors, exploring new ideas, and making memories with his family. A lifelong learner with a curious mind, he has a particular interest in philosophy, history, and learning new languages. He believes there’s always something new to discover, whether it’s through a good book, a new experience, or a meaningful conversation.
Family is an especially important part of his life. He loves spending time playing board games with his family and coaching his daughter’s soccer team. Whether he’s enjoying a little friendly competition around the game table or cheering on his daughter and her teammates from the sidelines, Dr. Kosta appreciates the simple joys of family life.
For Dr. Kosta, the same values that matter most outside the office — patience, kindness, curiosity, and genuine connection — are at the heart of how he approaches caring for his patients.
A Personal Message from Dr. Kosta
“I want my patients to feel comfortable asking questions, sharing their concerns, and being involved in decisions about their dental health. I believe that trust is something you earn over time by listening, being honest, and treating people with kindness. My greatest reward is knowing that patients feel confident in the care they receive and comfortable coming back to see us.”
Whether you’re new to Simi Valley, looking for a new dentist, or returning after some time away, Dr. Kosta and his team look forward to welcoming you and helping you maintain a healthy, beautiful smile for years to come.
