Meet Our Team

Iris Lee

Office Manager

Iris was born and raised in Taiwan but fell in love with the United States when she visited with her parents as a 9-year-old. She returned to the US as an international student at age 16 and went on to earn a Master of Science in Biotechnology at University of California Irvine and an undergraduate degree in Biological Science from University of California Riverside.

Iris grew up watching her parents work together as a team to run her father’s medical practice in Taiwan. This gave her confidence that she could assist her husband Dr. Justin in running his dream practice with all the knowledge and experiences her parents passed down to her. Though her professional background is more scientific, Iris welcomes this opportunity to explore her abilities as the office manager for Birch Dental.

Iris and Dr. Justin dated for nine years before they were married, and they are now the proud parents of a daughter and son. In her free time, Iris loves doing arts and crafts, making cute toys and houses out of boxes for her kids to play. She also loves taking photos for her family and friends.

Iris says: “I am working and raising two kids, so I understand how tough it is to look after yourself, but our health is very important. We have to be there for our loved ones, and I will do my very best to make sure you are healthy and connected to your work and family at the same time!”

Kathleen Juco-Sarver

Registered Dental Hygienist

Kathleen comes from a large, loud, and loving family in West Covina, California, where she was born and raised. Though life can get busy, Kathleen always looks fondly forward to next chance she can get back together with her ever-growing family again.

It was at West Coast University that Kathleen earned both her Bachelor of Science in Dental Hygiene, but also her Masters of Health Administration.

Kathleen’s favorite part of her job is the people she gets to meet. As a people person, she loves to get to understand every person in her chair and help them with their oral hygiene goals.

When Kathleen is away from the office, she loves to explore her creative side, whether it’s trying out a new recipe, a new sport like golf, tennis, or learning the lyrics to her new favorite song. Of course, a cozy evening in with her dog, Bane is always a remedy for a long day.
