Yaffa Liebermann was born in Kfar-Ata, Israel in 1945. She became a Physical Therapist and served in the Israel Defense Forces during the 1967 war, where she gained experience treating war-related injuries from both sides of the fence. Yaffa worked in a variety of settings: hospitals, out-patients, psychiatric facilities, home care rehabilitation for spinal cord, and brain trauma in Israel, Switzerland, and the U.S.A. (Virginia and New Jersey). She found her love and passion while working with the elderly in the nursing home environment in New Jersey. Yaffa became a Geriatric Certified Specialist (GCS), board certified by the American Physical Therapy Association (APTA) in 1998.In 1996, Yaffa founded Prime Rehabilitation Services, Inc, along with her husband and her daughter Tamar, with the goal of providing the highest quality rehabilitation services to sub-acute nursing home facilities throughout New Jersey, New York, and Pennsylvania.From working in the field, she saw the need to author four books. Her first book was focused on care for a stroke patient, instructing caregivers on the proper care of patients in the first few days after the stroke and continued home care. Three more books were about correct children's posture, with the hope that they will learn how to stand up straight at a young age and carry their bodies with pride.
