Martin has held a great interest in mental health and religious issues since his teens and has spent a major part of his life as a volunteer and campaigner in the mental health field.
During the last twenty five years he extended his interest in mental health particularly through his interfaith work and spirituality. In furtherance of his concern in the late 90s he became a founding member of the Advisory Council of the Three Faiths Forum (a national forum of the three Abrahamic faiths) and co-chaired its medical group. He founded and chaired The Jewish Society for the Mentally Handicapped in 1976 and was later a trustee for many years of the merged Ravenswood Foundation (now Norwood, of which HM The Queen is Patron, the organisation provides residential care and services for people with learning disabilities).
Extending his interest across the whole spectrum of mental health, in 1989 he founded The Jewish Association for Mental Illness, (JAMI) of which he remains Honorary Life President. Through his initiative JAMI is now the largest Jewish Mental Health service provider in the UK.
Martin was invited and served on the advisory committees on both MIND and MENCAP in the 1980s. Also on an advisory review committee on the Mental Health Act.
During the mid 1990s he was invited to join a working group on religion and mental health at the former Health Education Authority. In 2003 he was asked to take over the chair and subsequently registered the religion, mental health and spirituality group as a separate multi-faith/inter-faith charity under the title The National Spirituality andMental Health Forum. Soon after the Forum was established he worked closely with the late Professor Peter Gilbert. In 2006 he was invited by Christine King the vice-chancellor to become a visiting professor at Staffordshire University.
In 2011, Martin registered the spirituality research charity The British Association for the Study of Spirituality, and became its first Honorary Treasurer, and remains a member.
Martin has been involved in research and has served on several government department consultative committees over many years. A contributor to the All Party Parliamentary Group on Mental Health. He has organised, chaired and presented at numerous seminars and conferences on mental health, religion and spirituality topics, and continues to do so. He has written many papers, contributed to books and has appeared on radio and TV on several occasions.
For eleven years Martin served as a mentor for The Princes Trust.
In addition to his academic and professional qualifications, Martin was elected a Life Fellow of The Royal Society of Arts and a Life Fellow of The Royal Society of Medicine
