At 13 years of age, Dr. Grosswasser suffered a fracture of the spine. His family was told that surgery would be required and that a long (Harrington) rod would be surgically implanted from the base of his neck to his lower back. In an attempt to avoid surgery, Dr. Grosswasser’s family sought treatment with a Chiropractor. The impact the Chiropractic treatment had on his life was huge as he was able to avoid the surgery and set himself on a course to have that same impact on the world.

Through an accelerated undergraduate program, Dr. Grosswasser was able to complete his pre-Chiropractic credits in just two years.
