Leonard returned to the United States in 1970 and settled in Berkeley, California where he opened a school of physical theatre, attracting students from around the world. Leonard's one-man shows have received critical acclaim. He has performed and taught at theatres and festivals throughout the United States, Europe, Brazil, New Zealand, and Australia. He was also a member of George Coates Performance Works and traveled widely with the company.

In 1973 he traveled to Bali to study Balinese mask theatre. While there he was invited by his teacher to perform with him local village and temple festivals. He returned to Bali in 1978 to study mask carving.

In 1986 he co-founded Life On The Water, a contemporary theatre in San Francisco presenting new work.

In 1991, Leonard created Eco-Rap, an environmental education program combining ecology and rap music as a way to educate inner city youth about urgent social issues. He operated the program for five years.

Leonard has written three books on Paris. Two walking guides: Walks Through Lost Paris – 2002, Paris, A Journey Through Time – 2008, and Paris Postcards - The Golden Age – 2010. His fourth book, A Small Moment of Great Illumination, is about the the life of the 17th century Anglo-Irish healer Valentine Greatrakes.

Since 2006 Leonard has been a dedicated tutor at Richmond College Prep, a charter school in the Iron Triangle neighborhood of North Richmond, where he works with young children needing mentoring. He also created a program there, Junior Explorers, an all day excursion around the San Francisco Bay to give the young children the opportunity to explore the Bay's bridges, beaches, islands, as well as San Francisco itself, an experience many of them have never had.
