Life Enrichment Therapy (LET) was developed by Mark Hendler. It focuses on touch as a therapeutic agent. Touch is seen as a process of self expression for individuals seeking self growth and finding meaning. Through massage, a person opens up in a refreshing experience.

LET is an interpersonal approach between therapist and participant based on the premise that touch has value. Life enrichment occurs throughout life. Through massage and touch, awareness, and other tools, persons explore what it means to be human.
