Recently, she has been spending her spare time at home in the crafts room doing unique projects for family, friends, and the office.

Theresa Hoang, DDS

Dr. Theresa Hoang (Dr. H 2.0) is a cosmetic, family, implant, and general dentist practicing at Las Positas Family Dental in Livermore, California.

Dr. H 2.0 received her bachelor’s degree in psychology from the University of Washington and graduated from the University of the Pacific Arthur A. Dugoni School of Dentistry.

As you may have guessed, Dr. H 2.0 is Dr. Thi Hoang’s spunky younger sister who is equally as passionate about her dental career. Dr. H admires the caring, family-friendly environment at Las Positas Family Dental and is heavily inspired to help anxious patients overcome their fear of going to the dentist. She works diligently to set up an environment that allows for open communication between her and her patients and ensures that her patients understand the “whys” of the treatments that she recommends. She is always ready to tend to her patients’ needs and brings a big smile to their faces with her humor.

In her spare time, Dr. H enjoys traveling, dining at local restaurants, binge-watching Netflix shows, and spending time with her five nieces. On the weekends, you can probably catch Dr. H at a concert or music festival. If you have any restaurant or TV show recommendations, she is always open to them!

Kawelona Doctolero- Tolentino, RDH

Kawe graduated from the dental hygiene program at Chabot College. Kawe was actually born in Hawaii, on the island of O’ahu, and moved to California when she was a child. Prior to becoming a hygienist, Kawe worked part time at Auntie Anne’s Pretzels, then began her journey in the dental field as a dental assistant.

She always saw herself working in the medical field and was torn about becoming a nurse because she wanted a field more focused and specialized. Kawe realized that she grew up in a family that did not take care of their teeth, and she wanted to do better for them and herself. She wanted to take better care of her own oral health as well as educate her family on the importance of dental hygiene. That sole realization determined her career choice, becoming a dental hygienist to not only share her knowledge with her family, but also better her community. Kawe loves that being a dental hygienist can be challenging but rewarding and fulfilling at the same time. She enjoys helping patients build their self -esteem by fixing their teeth and smiles. The most rewarding part of her job is being able to put a patient’s anxiety and fears about dentistry at ease.

In Kawe’s spare time, she loves to spend time with her family. Some of her hobbies include hula dancing, bike riding, walking her dog, hiking around the bay and going on adventures with her boyfriend. Kawe enjoys catching up on Netflix series and reading mystery, thriller and suspense novels. An interesting fact about Kawe is that she is a lefty! Being left-handed in dentistry is not only rare, but can be challenging to work with a team that is mainly right handed. In the future, Kawe would like to become a hygienist that is able to travel to different parts of the world and educate patients in need.
