Mrs. Tsang is founder of EHD with the vision of bringing holistic development to children and adults through training, alternative therapies and activities. She is a registered Occupational Therapist and is one of the pioneers in Hong Kong. She was one of the few sent by HK Government to UK for training and started practicing Occupational Therapy since 1977. Alternative therapies then caught her attention and she added CranioSacral Therapy and related therapies to her repertoir since 2005. She has also brought training courses of these therapies to Hong Kong for the benefit of anyone who is interested in holistic health.
