Lash Group was founded in 1986 as a healthcare consulting firm, so our roots can be found in how we strategically collaborate with our clients. Our operational practice was launched in Charlotte, NC in 1993 by Peyton Howell, a leading expert and authority on health policy and healthcare market trends (and now President of Global Sourcing and Manufacturer Relations for AmerisourceBergen). This policy experience was combined with operational expertise and leadership from Tracy Foster in 1995 to drive the success and growth of Lash Group access and adherence programs. As president of the organization, Ms. Foster continues to lead Lash Group today. 

Lash Group became a part of AmerisourceBergen in 1998, and has continued an impressive track record of success by acquiring TheraCom and Premier Source in 2011, resulting in an unmatched offering of comprehensive patient support services. In 2013, Lash Group and TheraCom successfully integrated, and the company moved forward under the Lash Group brand name, while powering the company's Integrated Pharmacy Services and Wholesale Solutions as the TheraCom Pharmacy. Through Premier Source, Lash Group provides seamless access to an array of services and solutions to meet the unique needs of diagnostic and personalized medicine products.

Lash Group’s headquarters are located in Fort Mill, South Carolina, with additional operational centers in North Carolina, Maryland, Pennsylvania, Texas and TheraCom facilities in Maryland, Nevada and Kentucky.
