About Us
Susan Lawrence, M.D., Founder and Executive Director, The
Catalyst Foundation

A native of Brooklyn, New York, Susan Lawrence entered Barnard
College at the age of 14 to escape a troubled family. She was inspired
and mentored by Dr. Christiaan Barnard, the South African surgeon
who performed the world’s first human heart transplant. Susan entered
Baylor College of Medicine at 18. A rotation in medical oncology drew
her to work with the terminally ill. She became a board certified
internist and medical oncologist and opened her practice of medical
oncology in Lancaster, California, in 1985.

When many local doctors declined to treat people living with AIDS,
Susan welcomed those patients into her practice. In 1992 she and her
husband, Sonny Bartz (who passed on due to AIDS the following year),
launched The Catalyst Foundation.  Susan closed her private medical
practice and became Catalyst’s full time Executive Director; currently,
in addition to the Creating a Healing Society program, Catalyst provides
free medical care and supportive services to people living with HIV
and/or Hepatitis C.  Susan is grateful to have been able to use the
difficulties of her life to be of service to others through the development
of The Catalyst Foundation, especially the Creating a Healing Society
program.
