Karina Stewart  (Class of 1994)

Karina Stewart received her BA degree from Princeton University with a major in Cultural Anthropology. Growing up in Mexico, Karina was exposed to holistic medicine and meditation at an early age. She recalled practicing meditation and yoga in her teenage years as part of her daily routine along with a vegetarian diet at home. By chance in the early 90s’, Karina met Hua Ching Ni, the chancellor of Yo San University. She was impressed by him and his teachings and wanted to learn more about the Taoist philosophy and Chinese Medicine. That’s when she began her long journey through the world of Traditional Chinese Medicine.
Several months after graduating from Yo San,Karina married John Stewart, and together,they moved to Kathmandu, Nepal. There she opened a TCM clinic and began treating patients. Finding every opportunity to better her skills, Karina travelled to Japan and China to learn from the finest teachers and practitioner she could find. Constantly looking for something meaningful to do, Karina took part in building a company that produced handmade herbal products, and cultivated an herbal garden. She experimented with making Chinese Medicinal wines and found a formula that helped two infertile couples conceive.

When Karina and John married, they dreamed of one day creating a wellness resort. Years later, while traveling to Thailand for personal health reasons, John came across a large piece of land in Koh Samui. He fell in love with the tranquility and beauty of the place, as well as its history as a place for meditation and retreat. In 2001, Karina and John moved to Koh Samui and began planning for the wellness sanctuary of their dreams. It took them 3 years to get permission and licensing from the local government to create the necessary infrastructure, and to complete the architectural and landscape designs. It took them another year to build the resort. In November 2005, Kamalaya Wellness Sanctuary and Holistic Spa opened its doors. Yoga, stress reduction, and detox are some of the programs offered at the spa. The architecture is designed to help guests connect with nature and promote relaxation and wellbeing. Meals served at the restaurants focus on healthy eating with the finest yet simple ingredients. It was no surprise that in three short years,Kamalaya was named The Destination Spa of the Year by AsiaSpa Awards. Since then, Kamalaya continues to receive prestigious awards year after year, including the most recent Prime Minister’s Award for Excellence in Thailand. Karina truly believes that the reason for her success is due to the people working at Kamalaya. They are naturally caring and have the amazing ability to stay in tune with the needs of the guests. Karina remains involved as Brand/Concept Director. She continues to explore and design wellness programs based on the fundamental principles of TCM she learned at YSU.

When asked what advice she has for students who are just starting the YSU program, Karina urges them to go beyond the classroom learning and clinical training. “Embrace the entire life style,” she stressed, “learn I-Ching, Tai Chi, and read the Taoist texts.’ Above all, “Be inspired and focus on your passion. And don’t try to be good in everything… don’t be afraid to specialize in any one aspect of TCM.

Nini Mai and Jonah Ewell (Class of 2009)

Together, Nini and Jonah established a successful TCM herbal dispensary company, Fat Turtle Herbs, based in Culver City, California. “In the course of our studies at Yo San, we came to realize the need for a full service TCM herbal pharmacy that not only offers custom fulfillment of herbal formulas, but also provides educational support to both the acupuncture profession and the public in general” said Nini. “We were inspired by the awesome herb instructors we had at Yo San, and the supportive environment at school really made a difference; we felt encouraged and were optimistic we would make it,” added Jonah. Over the last two years, their company has grown from a part-time student-intern venture into a full-fledged successful business with four employees and orders coming in from Hawaii to Florida. In addition to the herbal company, Nini also maintains a thriving private acupuncture practice in the west Los Angeles area. To fulfill their mission of educational support to the profession, Fat Turtle Herbs made a donation to the Yo San University Alumni Scholarship fund in 2009, “as a token of appreciation for the education we received at Yo San, as well as to encourage other Yo San students to strive for success after graduation.” What advice do Nini and Jonah have for other students or junior practitioners on how to be successful? “The key is to be confident at what you do and don’t stop learning” Jonah offered. “Develop an ‘entrepreneurial hustle’ – you’ve got to get out there, identify opportunities and put in time and energy to make things happen”. “Good basic business acumen definitely helps,” added Nini, flashing a wide grin.
