Dennis B Miller

Dennis, the founder of the Yoga Waikiki Studio, received a Bachelor of Arts degree in Dance from UH Manoa in 2000, and performed for 15 years with the Iona Contemporary Dance Theatre in Honolulu, from 1992 to 2007.  On a weekly basis since 1998, he started to teach free Butoh Dance Improv classes in the style of the Iona Dance company choreographer, Cheryl Flaharty.  These free classes were attended by friends of the dance company, and provided the most nurturing process imaginable for learning how to teach. 


By the year 2000, Dennis took his first Iyengar Yoga class and immediately fell in love with it.  Overtime, he began to incorporate Iyengar Yoga into a dance warm up. This makes the whole yoga experience more holistic and engaging.


Over time, the Shiatsu & Massage Center grew, moved to the Waikiki Trade Center in 2007, to the Waikiki Beachwalk in 2011, and by  Feb 3, 2019, up to the present, has moved to the International Market Place. 


In 2008 Dennis and his partner and wife Petula set up Spa Pure in the Courtyard by Marriott Waikiki Beach Hotel.  Dennis and Petula continue to offer his signature service of Ocean Massage, a floating massage in a warm salt pool.


Dennis attended the first seven annual yoga festivals at north shore, starting with Spirit Union Festival in 2009.  These festivals bring amazing yoga talent to Hawaii and are an immersive opportunity to dive deep into yoga exploration; he highly recommends Wanderlust, which took over from the also excellent Spirit Union.

The result of Dennis’s various movement explorations has been an appreciation for the vitality of stillness. Further, the many movement pathways which result from developing an awareness of not limiting our possibilities is also one of the things that Dennis has learned and mastered through time. Dennis is also an advocate for health policy with an administrative overhead of less than 8%, including payer and provider.  (Our current admin overhead, including payer and provider, is over 30%)  This is one way of describing Universal Single Payer Healthcare.

As the years went by, the warm up became longer, and the dance portion became shorter.  Also, in 2000, Dennis took over ownership of the Shiatsu & Massage Center, in the Continental Surf Hotel.
