“I have strong foundations in clinical medicine, medical diagnostics, team leadership and
business operations.  Over the past 20 years, I have succeeded as an attending physician and
medical director.  Due to the growing economic pressures on healthcare delivery, I decided to
broaden my business expertise. I accomplished this managing complex strategies at two
investment firms, joining the boards of two medical diagnostic companies, and passing the first
level of the CFA (Certified Financial Analyst) program.”

Dr. Jaeggli has practiced medicine in a number of emergency rooms, as well as worked for a Global Neuro-Diagnostics; which is a private fast growing medical diagnostic company providing home video EEG services.
