Our well-renowned and highly specialized dentist – Dr. Katherine M. Tsap, a resident of Southern California, has her heart and soul into dentistry and focuses on the entire family’s teeth and oral health concerns and care.

She holds a Bachelor of Science Degree in Biology from San Diego State University and a Doctor's Degree in Dental Surgery from the prestigious University of Pacific, Arthur A. Dugoni School of Dentistry in San Francisco. She is dedicated to restoring, preventing, and cosmetically enhancing her patients’ health and self-confidence.

Residing in Westlake Village with her husband and two children, she enjoys spending her free time with family and friends, trying new restaurants, hiking, and riding her Peloton.



After eight years in the dental field as an RDA and Certified Orthodontic Assistant, I graduated valedictorian from hygiene school. While there I had the opportunity to participate in a wide range of community service and education programs. I am grateful I had the opportunity to share the value of oral health care and provide caring treatment for adults and children. I continue to volunteer for service in my community, and consider it an important part of my career. We all share a passion for dentistry and providing our patients with the best treatment available. I love my work and treat each patient as if they were family!



Originally from Massachusetts, my very first job in High School was in a dental office. I knew from that point on that I wanted to make my career in the dental field. I became a Registered Dental Assistant and a Certified Orthodontic Assistant. Then I continued my education and graduated from Dental Hygiene School with the coveted Clinical Excellence Award. I enjoy seeing my patients each time they return and providing them with excellent care and a gentle touch. I have a passion and dedication to my field, and knowing I can help my patients maintain a beautiful and healthy smile, in turn, puts a smile on my face! I live right here in Westlake Village with my husband and two children and enjoy reading, camping, and spending time with my family.



I have been in the dental field since 2005. I love my job as a dental hygienist and I strive to make patients feel safe and comfortable. I enjoy educating patients and make them feel good about their smiles and oral health. My favorite part is getting to know patients and building good relationships with them.

When I am not at work, my favorite job is being a mom and wife. We love to camp, go to the river or lake, ride bikes, bake and spend time with family.


Front Office Coordinator

I was born in Long Beach, CA then moved to Agoura, CA in 1972. I graduated from Agoura High School and immediately went to Dental Assisting School. I have worked in the back office as well as the front office. I have had an obsession with teeth for as long as I can remember. I love knowing that Dr. Katherine can make a difference in making someone's smile better and that she genuinely cares about our patients. I have been married for over 30 yrs and have 2 grown children and 2 grandsons. Away from work, I enjoy riding dirt bikes, camping in our motorhome, and most of all being with our grandsons.


Dental Assistant

I was born in Minnesota and moved to sunny California when I was in middle school. My passion for dentistry began right after high school, with my first job in a dental office, and it has been my calling ever since. I have enjoyed helping patients and working with great professionals on creating healthy, beautiful smiles. I have been married for over 16 years and have four beautiful children. I also love animals and currently have two dogs, a cat, two bunnies, several fish, and a couple of hermit crabs. In my spare time, I love to swim, spend time at the gym, and travel.


Dental Assistant

I was born in the city of Walnut Creek, California and moved to Santa Fe, New Mexico when I was eight years old. I then settled down in beautiful Thousand Oaks, California, in 2012.  Due to my proclivity to help and care for people, I have been drawn to the field of dentistry. I decided to attend the Allied School of Dental Assisting, and graduated in 2019.  The same year, I met Dr. Katherine as her patient and fell in love with the Westlake Village Family Dentistry staff, joining them as a Dental Assistant.

As an outgoing and communicative person, my favorite part of the day is meeting new people and hearing their story. When not working, I enjoy working out, going to the beach, and trying new foods.
