Eventually her acting career brought her to Los Angeles where she would experience yet another career change that would take on a more meaningful new direction.
In 2006, Elizabeth began a career in the medical field with Team Surgical working as a Sales Representative in Surgical/Capital Equipment Division. She quickly ‘cut her teeth’ in the Medical Field and developed strong and lasting relationships with the Orthopedic Surgeons in her respected Territory.

It is relative to point out that Elizabeth was born with a ‘Congenital Physical Abnormality’ of her lower right leg; subsequently, she had 7 additional unsuccessful surgeries to correct the aliment that resulted in an amputation just below her right knee at age 11. Though what may seem as a deterrent for success or an obstacle in the pursuit of dreams has only fueled Elizabeth’s desire and need to assist others with similar predicaments.
Elizabeth has been the motivating factor and key initiative for the development of Specialized Orthopedic Solution’s — Prosthetic Division.
