Born in Nepal, I moved to the US at the age of 14 and graduated Mercer Island High School in 1990. I went to Bellevue Community College for two years then transferred to the University of Washington to study business, after which, I moved to Hawaii to study computer information systems. I enjoy the outdoors. I have completed the 7 summits, the seven highest mountains, in 42 climbing days around the world. I am also a father of a beautiful 8 year old daughter, Amalia Tsering Sherpa. Because leadership is important to me, I like to set great examples in the community. I am a people person and I like to do social work by helping people in underdeveloped countries. I love dental volunteering and traveling to help people to understand the importance of good oral health and to have the best smiles. Through Essence of Dentistry & 7 Summits Foundation, we have seen over 10,000 women and children in remote villages of Nepal. I also organize tour, travel, Safari, Trek & Expedition to Nepal, Tibet, Bhutan, India, Africa, Argentina, Chile, Peru and more.

Registered Dental Hygienist

My name is Kazi, and I was born on the Japanese island of Hokkaido near the city of Sapporo. I earned a Bachelor's degree in Japanese literature from Fuji Women's College, and I attended Marian College in Indiana for one school year through a foreign study program. I worked in IT in Japan after graduating from college but moved to Seattle (my husband's home town) in 2004. I studied medical assisting at Seattle Vocational Institute and worked in Redmond as a MA. After staying home for several years to raise our two sons, I studied at Lake Washington Institute of Technology in order to earn my license as a Registered Dental Hygienist.

The aspect of dental hygiene that I find most rewarding is educating patients in steps to improve and maintain oral health. Having seen some of my own relatives lose their teeth at an early age due to the lack of professional oral care, I feel it is extremely important to look after the well-being of my patients and to accommodate their needs to the best of my ability.

I enjoy gardening, playing the piano, reading, yoga, sewing and knitting. My family and I love to find opportunities to ride bicycles and to hike the Northwest trails.

Registered Dental Hygienist

I was born in Mukliteo, WA and as a Washingtonian I enjoy the scenic outdoors our state has to offer. During my free time I am on a hike with my dog, or exploring different restaurants with my friends or sister. You can find me either in the front office helping with office duties, scheduling appointments and, at the back assisting the doctors. Though, I just started my dental career as an assistant it has been truly a rewarding experience learning from Dr. Han and the rest of the team. I choose this field because I like working hands-on, and I have a passion to help people achieve or maintain a sparkling smile. My goal is to bring you the best experience possible. I enjoy meeting new people and cannot wait to greet you with a welcoming smile!
