He specialized in bringing a collaborative, existential psychotherapeutic approach to the struggles of adults who deal with chronic and/or serious medical illness, trauma, physical disability, sexual difficulty, or death and dying. He utilized his subspecialty training and clinical experience in working with people (and their families) who have "different" central nervous systems due to brain injury or other neurological problems. Although his independent practice of clinical psychology closed in July of 2013, Eliezer continues to work on a long-term project to develop a consilient narrative that accounts for the defining features and limits of humanness.
