JEN MARSHALL
Chief of Staff
Jen is our go-to problem solver — you will find her working behind the scenes strategizing and managing our practice growth, coordinating our efforts in research, education, advocacy & outreach, and planning events & communication. Jen spent 20+ years in public service as a researcher and program/project manager.
Personally impacted and inspired by our mission, she pivoted careers in 2024 and is dedicating herself to advancing women’s sexual and menopausal health.
She is a mom to two teenagers and spends her free time volunteering with her local conservation league and cub scout pack, as well as mentoring and coaching early/mid-career women.
COLLEEN FISHER
Executive Assistant
Colleen brings nearly two decades of communications and project management experience — along with 27 years as a nationally recognized fitness instructor and health advocate — to the team. She has supported physicians, health leaders, nonprofits, and corporations with marketing, branding, event coordination, advocacy, fundraising, community building, and digital content development. She also captained an indoor-cycling Cycle for Survival team for 12 years, raising $2.6M for rare-cancer research and earning MSK’s Game Changer Award.
Currently navigating menopause herself, Colleen brings both empathy and humor to the practice’s mission — and believes evidence-based care (and HRT – wink, wink) can make all the difference.
At the practice, she supports daily operations, project flow, and communications, helping ensure every touchpoint reflects the clarity, compassion, and excellence central to Dr. Rubin’s mission. She and her husband live in Chevy Chase, Maryland, and are the proud parents of four sons.
