Walter Lee -an entrepreneur and activist on a mission to empower children with disabilities in South East Asia through his Zy Movement Foundation.

The inspiration behind the Zy Movement Foundation is Walter’s third son. “Zy was born with one complete left arm, half a right arm, no right leg, a malformed left leg with three toes and dislocated hip joints. He is otherwise just like any other child.”

“Over the years, we have been to numerous hospitals, sought assistance from different groups and associations, e-consulted from one continent to another, talking to pediatric orthopedic specialists about little Zy’s case and his chance of standing and walking. Time and again, we have been told to be patient, and to wait and see! I knew Zy would be able to get around fine in a wheelchair but that just wasn’t enough for me! I wanted him to have an option to stand and walk if he so chooses to. This desire of mine led me to make the following discovery.

“There is a pediatric orthopedic specialist, Professor Carstens at the University of Heidelberg who I visited in October 2007 in Germany. Prof. Carstens and his team of prosthetic specialists told me they were 80% confident they could enable little Zy to stand and walk. They showed me their work and gave me a prognosis of what, when and how they will be treating little Zy in the next few years. I was overwhelmed and hopeful again. That is exactly what I had been looking for. 

“The thought of the millions of disabled children in Thailand and South East Asia came into my mind. If I should be spending all these resources to treat one child, why couldn’t the treatment process be properly documented and disseminated so that potentially millions of disabled children might benefit from it? The important thing is understanding and learning the fundamentals behind the treatment process. That was the seed of thought that gave birth to the Zy Movement Foundation.

“It always gives me pride and pleasure talking about a social enterprise like Human Study, willing the determination of only a few, to boldly growing from strength to strength in bringing quality of life to the people with movement challenges around the world!”

Walter is the CEO of Venturetec Marketing Co. Ltd., an international joint-venture which creates, markets and distributes its own brands of premium seafood and gourmet food products domestically and internationally; Director of Exquisine System Co., Ltd. an international joint-venture restaurant franchise and management company operating 68 restaurants in 21 countries; and founder of The V-School, a boutique culinary management institute specializing in the art and science of Japanese and Thai cuisine.
