Kristen Hunter : Vice President, Content

Leveraging 20+ years of experience producing conferences in the life science industries, Kristen brings with her to Momentum a strong portfolio of established events, the experience, drive, and ambition to build and manage a team of Conference Producers and the tools to position them for success.

Kristen joined Momentum in January of 2022 after leaving Fierce Life Sciences, a division of Questex, as Senior Event Director. She proved agility, adaptability and durability during a job-changing pandemic that occurred shortly after a company-wide operations/system integration was initiated. She embraced the disruption as a chance to innovate and took the lead on reinventing established events as COVID-friendly virtual options. Experimenting with different mediums and offerings during this fast-changing time, she leveraged decades of experience to quickly determine the best and most strategic approaches, generating many best practices and guidance tools for colleagues to follow, as everyone quickly adapted to the COVID times.

Having started her career at the Biotech Industry Organization (BIO), she then moved to IIR, now Informa, where she met Bryon Main, currently Momentum’s COO and Co-Principal. She then followed Bryon to his newly created company, ExL Events, and helped build the company from five employees to 85 annual events, when it was acquired by Fierce/Questex. She’s thrilled to be back working with Bryon in a small company environment and excited to help Momentum reach its full potential.

Kristen grew up in Annapolis, Maryland but is now a Jersey Girl residing in Basking Ridge, New Jersey with her active-duty Coast Guard Officer spouse, two kids and two cats.
