Dana W. Soper

Co-Founder & Chief Executive Officer

Dana is a proven healthcare executive with a track record of more than 25 years starting, acquiring, integrating and growing healthcare-related businesses while continuing to support their unique culture and strengths. She co-founded CORDENTAL Group® and is dedicated to the continued success and growth for each individual affiliate by empowering them to provide quality care and exceptional customer service in a collaborative environment that maximizes every member’s potential.

She began her career as a pharmaceutical sales executive and then moved into operations upon completion of her MBA. As a joint venture, she formed Infusion Partners, which she grew to over $60M in revenue and 17 locations before selling it in 2007.

Dana partnered with private equity in 2008 to form CarePoint Partners, a home infusion company that grew to over $150M in revenue over five years. It quickly became one of the top five infusion providers in the country. Dana’s efforts were concentrated on building the infrastructure of the company around a team of professionals whose sole purpose was to support the clinical sites, the newly acquired companies, and their owners.

This philosophy of supporting superior patient care drove the success of the company that thrived under her leadership. Removing the challenges of running a business and providing a renewed focus on patient care were the keys to continued growth. CarePoint Partners was considered the acquirer of choice in the home infusion industry because of the individualized approach to acquisitions and the culture of the company that Dana established.

After the sale of CarePoint in 2013, Dana has been involved in other startups and in consulting roles with private equity firms. She is a board member of ITC Compounding Pharmacy, MedaCheck — a startup company that provides a medication adherence program, and Anne Arundel Dermatology Management.

Dana is a graduate of the West Virginia University School of Pharmacy and holds an MBA from Xavier University in Cincinnati. She has been a finalist for the Ernst & Young Entrepreneur of the Year Award, won both the Association for Corporate Growth Deal Maker Award and the Fast 55 Award for Growth when leading CarePoint Partners.
