WellStreet: development and operation of urgent care networks for health systems

WellStreet is an Atlanta, Georgia-based company that positions itself as a national partner to health systems to optimize and scale their retail urgent care strategies through flexible, tailored partnership models. Its activity is built around two formulas: operational management and joint ventures aimed at growing urgent care networks.

Partnership models and services for health systems

The company offers its health system partners a range of services, including the transformation of existing urgent care networks, accelerating the growth of new networks, and expanding and optimizing those already in operation. WellStreet states that its services cover every phase of the process, from initial planning and site selection to construction, staffing and day-to-day operations.

Operational indicators and cited results

According to information published by the company itself, its model generates volumes of new and returning patients for the health system's brand, with one in every three patients being new to that system. The company reports an average satisfaction score (NPS) of 81 and states that its clinics are among the 16% of urgent care centers fully accredited by the Urgent Care Association of America. On the financial side, it mentions average service line profitability of 15% and cites the case of a partnership that in 2024 generated $33 million in revenue and 60,000 new patients, with profit margins above 18%. It also highlights care coordination between urgent care, primary care and specialty care, supported by integrated electronic medical record (EMR) systems.

Track record and partnerships with health systems

WellStreet was founded in 2011 as an independent urgent care operator in Atlanta, Georgia, and in its first year of operations reached a network of seven locations. In 2014 its partnership model emerged through a collaboration with Piedmont Healthcare to develop and expand the Piedmont Urgent Care brand across North Georgia. In 2019 it launched a partnership with Corewell Health to deploy and operate a network of urgent care centers under the Corewell Health Urgent Care brand in Southeastern Michigan. In 2023 new partnerships were added with University Hospitals and Prisma Health.

The company's leadership includes Lisa Mikkelsen as Chief Executive Officer (CEO), who joined in March 2020, with 17 years of multi-unit operations experience and previously Chief Operating Officer at Benevis Dental Practice Management Services. Michael Duchynski, a physician board-certified in emergency medicine, has served as Chief Medical Officer (CMO) since November 2021.
