After joining Ann Wigmore's Boston-based Rising Sun Christianity movement, Kulvinskas co-founded, with Wigmore, the Hippocrates Health Institute, a health resort in the United States, in the late 1960s where he was Director of Research, and is active in the living foods movement.
After co-founding the Hippocrates Health Institute, he began 35 years operating as a practitioner in the area of holistic treatments and techniques. He is also a lecturer, chef, and a Bishop of the First Christian Essene Church of Christ (San Diego, California).
As a nutritionist, he was the personal health consultant to comedian/activist Dick Gregory during his 900-mile run for peace, and has been a Nutritional and Education Director at Gregory’s Obesity & Substance Abuse Resorts (Florida & Bahamas). His theories on cancer were practised at the Hippocrate Institute, and documented in his book "Survival in the 21st Century", along with his theories on a new model of menstruation with program to eliminate PMS.
Speaker and advocate
After opening a culinary school in 2002, Kulvinskas continued to be active in enzymatic theories and development of foods, as well as lecturing and writing in the field of alternative wellness and enzymatic therapies. He was one of the first to popularize the long out-of-print works of Chicago enzyme researcher Dr. Edward Howell (October 30, 1898 - March 30, 1988) of the Lindlahr Sanitarium (Illinois). Kulvinskas was also one of the first to promote sprouts, algae, wheatgrass, plant enzymes and herbal formulations to offset the claimed impact of cooked foods, environmental pollution and inherited weaknesses.
Kulvinskas currently offers lectures and retreats on healthy living at his home in Montezuma, Costa Rica.
