JLL Partners and Water Street Healthcare Partners Complete Acquisition to Expand Life Sciences

CHICAGO and NEW YORK - March 19, 2018 – Water Street Healthcare Partners, a strategic investor focused exclusively on the health care industry, and JLL Partners, a leading middle-market private equity firm, announced today that they have completed their acquisition of Dohmen Life Science Services (“DLSS”) from its parent, The Dohmen Company.

The investment firms will merge DLSS with Water Street’s commercialization services platform, which was formed last year through the merger of Alliance Life Sciences, Health Strategies Group and The Access Group. With the addition of DLSS, the platform will expand its market access solutions to encompass patient support, channel, technology and compliance services, and become the leading independent provider of commercialization services to life sciences companies.

Jim Lang, executive chairman of the commercialization services platform, said, “We are thrilled to add DLSS and its highly regarded patient-centric capabilities to our platform. As one entity, we are ideally positioned to help our clients optimize the impact of important new products they are developing to support people who are battling complex and challenging diseases.”

Cynthia LaConte will step down as CEO of DLSS to remain with its former owner, The Dohmen Company. Dan Johnson will retire from his role as DLSS president and support the company’s transition to new ownership as an advisor. The remaining management team will report to Mr. Lang, who will also serve as CEO of DLSS.

DLSS will continue to operate under its existing name. Financial details of the acquisition are not being disclosed.


DLSS empowers hundreds of life science companies ranging from start up to fortune 500 with best-in-class outsourced infrastructure, insight and services by providing services in the areas of patient support, supply chain, compliance, finance and technology. DLSS acts as a seamless extension of our clients’ companies – reducing cost and complexity while strengthening and simplifying their connection with patients.
