Ben Trihub’s classes are a positive, safe, meditative space to come as you are. It’s an opportunity to drop in beneath the endless chatter of the mind and connect with your inner truth—your higher Self, the light within, the Divine. This is a place where there is nowhere to get to and nothing to get away from, just an invitation to rest in the “I Am.”

In a typical Kundalini class, we use many simple, powerful yogic tools—pranayama (breathing techniques), poses and movement, meditation, mantra, sound healing (live gong), relaxation, and more. Whether you’re new to yoga and meditation or have years of experience, all levels are welcome. The flow of the class is unhurried, giving you plenty of time to breathe, connect, and enjoy. Ben is also a musician and is passionate about sharing mantra-based music and sound healing.

Board Certified Acupuncturist
Dr. Eileen Han, PhD, LAc, is a licensed acupuncturist providing thoughtful, results-focused care in Las Vegas. She holds a Master’s Degree in Oriental Medicine from the University of East/West Medicine in Sunnyvale, California. She also completed a PhD in Acupuncture and Oriental Medicine from American Liberty University in Newport Beach, California. Her approach combines classical Chinese medicine with modern clinical understanding, helping patients find relief from pain, stress, and chronic conditions in a calm, supportive setting.

Dr. Han began her training early, spending many years immersed in her family’s acupuncture and Traditional Chinese Medicine supplies business. This hands-on foundation shaped her practical, precise approach to care. In 1999, she began formal medical studies and apprenticed with the late Dr. Richard Tan, an internationally respected acupuncture physician and creator of Balance Method Acupuncture.

Over 20 years, Dr. Han co-taught over 350 seminars and workshops alongside Dr. Tan in Europe, Asia, and Americas, helped refine and deliver the core curriculum. Before his passing in 2015, Dr. Tan personally entrusted Dr. Han with the responsibility of carrying his life’s work forward, naming her the official torch bearer of Balance Method Acupuncture.

What Is Balance Method Acupuncture?
Balance Method Acupuncture is a gentle, highly targeted style of acupuncture designed to help the body rebalance itself quickly and naturally. Rather than placing many needles directly at the site of pain, this method uses carefully selected points—often away from the problem area—to promote relief and improve function.
Many patients notice changes during or shortly after treatment. This approach is commonly used for pain, injuries, stress-related conditions, and a wide range of internal health concerns.

Dr. Han School and Global Medical Missions
Dr. Han is the Founder and Director of Dr. Han School of Acupuncture (formerly Academy of Acupuncture), a global learning institute dedicated to teaching Balance Method Acupuncture.
She has trained acupuncturists from around the world, earning respect for her clear teaching style, clinical rigor, and ability to translate complex theory into practical, results-driven application. Her ongoing role as an educator continually refines her diagnostic skills—directly benefiting her patients.
In addition to teaching, Dr. Han has participated in and led Medical Missions worldwide, providing acupuncture care in underserved and challenging clinical environments. These experiences have strengthened her ability to treat complex conditions efficiently and compassionately, often under limited-resource circumstances.

While Dr. Han’s experience spans decades and continents, her focus in Las Vegas is simple and personal: providing exceptional care to each individual patient.
