Vivian Sales
General Dentist

About Me

Growing up, Dr. Sales was inspired by the work of her own dentist, as well as her mother, a dental assistant. After witnessing the care and success of these mentors, she decided to pursue dentistry as her own career. With over a decade of experience as a General Dentist, she most enjoys being able to bring smiles to her patients’ faces.

A graduate of University of West Florida in the area of Biology, Dr. Sales went on to University of Florida College of Dentistry for her D.M.D. degree. After completing her studies, she went through two General Practice Residencies: the first focused on treating medically compromised patients within a hospital setting, and the second focused on oral surgery and leading dental students in the urgent care clinic at UCLA.

Outside of her practice, Dr. Sales loves spending time with her two children. She enjoys outdoor activities, watching movies, and doing Zumba!

Haris Lakisic

About Me

Entering the field of dentistry was a natural choice for Dr. Lakisic: his father and brother were both dentists, and introduced him to this profession of helping others. He enjoys being able to help relieve people’s pain and discomfort, as well as improve better health and esthetics.

Dr. Haris Lakisic grew up in Bosnia and Herzegovina, but became a refugee and escaped to Southern California at the age of 15 due to war in his homeland. After finishing high school in Costa Mesa, Dr. Lakisic attended Pepperdine University for his Bachelor’s degree, then received a scholarship to attend the University of Pennsylvania for his D.M.D. degree. During his four years of dental school, he was consistently ranked in the top 10 of his class.
Dr. Lakisic’s hobbies include travel, fishing, and outdoor activities.
