Dr. Valentine, D.O. – Medical Director

Principal Investigator

Dr. Valentine serves as the Medical Director at our Phoenix site, where she leads a dynamic team of principal and sub investigators in delivering high-quality, early-phase clinical research. Board-certified in Internal Medicine by the American Board of Internal Medicine (ABIM), she brings a unique blend of medical expertise and business acumen to her role, along with deep personal passion for the life-saving potential of new therapies.

Before earning her medical degree, Dr. Valentine built a decade-long career in business working for CDI Corporation, an international staffing company, rising through leadership roles from recruiter into sales, into management and ending with a global strategic accounts manager position. She later completed her medical training at Rocky Vista University College of Osteopathic Medicine in Denver, Colorado, and her Internal Medicine residency at the University of Arkansas, where she served as Chief Resident.

Dr. Valentine worked as a hospitalist prior to joining Celerion, including work during the COVID-19 pandemic and is a proud breast cancer survivor. Her experience receiving trastuzumab (Herceptin) a groundbreaking HER2-targeted therapy approved in 1998 that has transformed breast cancer treatment—fuels her commitment to advancing drug development through Phase 1 trials. Trastuzumab's development not only revolutionized breast cancer care but also laid the groundwork for the current paradigm of biomarker-driven drug discovery and development.

A proud University of Kansas alumni and Midwest native, Dr. Valentine is also a passionate advocate for menopause care and cancer survivorship. When she is not driving innovation in clinical research, you will find her hiking and exploring the great outdoors.
