Previous Roles

2022-2026

As co-founder and CEO of Digital Health New York (DHNY) launched in 2022, Bunny led a connected community that shares ideas, sparks new directions and creates success across the entire digital health ecosystem. She served as DHNY’s CEO from 2022 through February 2026. DHNY seeks to increase the visibility of New York City as a leader in healthcare innovation and showcase the companies and leaders creating the future of healthcare. DHNY Summit, its flagship event, convenes the community to facilitate an all-out sharing of content, ideas and innovations.

2009-2021

As co-founder and CEO of NYC Health Business Leaders (NYCHBL), Bunny created premier network of 5,000+ senior-level professionals, executives, entrepreneurs and leaders engaged in New York’s healthcare ecosystem. Founded in 2009, the organization played a key role in turning the city into a healthcare epicenter. What set NYCHBL apart from other organizations was its focus on the people and companies driving the innovation by supporting and promoting their success. NYCHBL started as a convener, yet became so much more – a trusted source of quality content, networking and leadership, including the renowned New York Healthcare Innovation reports and NYC Digital Health 100.

2016-2021

As director of Columbia Business School’s Healthcare Management Program, Bunny transformed an underperforming track into a prestigious healthcare center at a top 10 MBA program. As a result of her leadership, vision, and ability to drive results, she secured the first-ever endowed gift, increased applications by 20%, built a world-class Advisory Board, and created an ambitious, forward-thinking five-year strategic plan. Bunny also served as an Adjunct Professor teaching MBA students and industry professionals.

2010-2016

Bunny launched Ellerin Health Media (EHM), a boutique healthcare consultancy, to advise clients on digital and social marketing, business development, market entry, brand development and strategic communications. During this period, she also joined Intouch Solutions as Senior Vice President of Healthcare Professional Strategy and served as Chief Marketing Officer at Onsite Dental to help them rebrand and refine their marketing strategy.

2005-2010

Prior to launching EHM, Bunny was Managing Director of InterbrandHealth, a leading global brand consultancy that is part of Omnicom. She led the Research and Analytics division and spearheaded the firm’s efforts in the digital arena. Her team supported traditional quantitative and qualitative research as well as newer social media mining tools to understand brand strength among key stakeholders (physicians, patients, caregivers). 

1995-2005

Earlier in her career, Bunny worked with a number of venture-backed healthcare companies. She was Executive Vice President of Clinsights, where she led the end-to-end development of several online physician communities in cardiovascular disease and diabetes, most notably TCTMD for interventional cardiologists and vascular surgeons. She also managed the development of online post-market (Phase IV) clinical registries for medical device companies to help them capture critical information about recently launched products. Clinsights was acquired by PPD, one of the country’s largest CROs (contract research organization) in 2003.

Before Clinsights, Bunny spent five years in the physician practice management (PPM) industry where she worked with many clinical specialties to help doctors learn to assume and manage risk. She started as Director of Operations at Advanced Health Corporation (which went public in 1997) managing cardiology and orthopedic Independent Practice Associations (IPAs). She then joined Vivra Specialty Partners in 1997 as its Northeast Vice President to manage contracting and clinical data analytics for 14 single specialty networks ranging from urology (her favorite!) to oncology to podiatry.

Bunny is known for founding and leading the Harvard Business School Healthcare Alumni Association (HBSHAA) which celebrated its 20th anniversary in 2019.
