Insurance Coordinator

Maureen has been with the office for eight years. She wishes she found this office 20 years ago. She loves to facilitate and coordinate treatment to set appointments and setup financial arrangements to suit patients’ needs. In her time away from the office, she likes to travel and cook for her family, and she has a 1-year-old granddaughter!


Hygiene Coordinator

Taeko has recently joined the Barr family. She comes to us with many years of customer service experience and is excited to be part of the health care industry. When not at work, she enjoys gardening and has recently taken an interest in exotic plants. She also loves to spend time with her cat, Musubi, and is a licensed aesthetician.

Cheryl, RDH, BS

Registered Dental Hygienist

Cheryl has been working with Dr. Barr and our patients for just short of 41 years. Oral health is not isolated to the mouth and can influence either positivity or negatively one’s overall systemic body health. With much care, Cheryl treats each of her patients as a whole person not just a mouth. She enjoys cooking, gardening, and wine … especially the bubbles!

Laura, RDH, BS

Registered Dental Hygienist

Laura has been with Dr. Barr for 19 years. She treasures the many relationships she has built with her patients over the years. In her free time, she loves being outdoors and being active with her wonderful husband and two amazing children.

Kristin RDH, BS

Registered Dental Hygienist

Kristin has worked with us for just over four years after working an impressive 26 years at her previous office. She loves her job because she likes getting to know people. Outside the office, Kristin loves to be outdoors, where she enjoys hiking, camping and sailing. Most of her family vacations almost always involve nature and the great outdoors.


Dental Assistant

Nancy has been with the office for over 40 years. Nancy enjoys sterilizing and keeping things organized, (the place would fall apart without her.) When she is not at the office, she enjoys shopping, spending time with family, decorating for different holidays and baking.


Dental Assistant

Martha has worked side by side with Dr. Barr for over 36 years. They make a great team. Her greatest joy is the close relationships with each patient that have developed over the many years. Nothing gives her greater pleasure than relieving a patient’s anxiety, facing a major procedure and achieving an excellent result. She loves to travel to California to spend time with her son and new grandson!


Dental Assistant

Isabel is the newest member of our team, and she has over 15 years of experience. She is excited to continue her career with us. In her free time, she enjoys spending time with family, watching her kids play various sports and, whenever possible, catching up on sleep! We are thrilled to have her join us.
