On Thursday night July 9, 2015 Seewald Laboratories, Inc. again opened its doors to its friends and neighbors of Lycoming County.  The Williamsport/Lycoming Chamber of Commerce selected Seewald to host a PM Exchange event.  Seewald has been a member of the Chamber for many years and has partnered together with the County from projects like The Lycoming County Groundwater Baseline Study to Thursday evening’s event.  Chamber members were given a presentation of the long history of Seewald from its origin in 1939 to how it became the full-scale laboratory it is today.  Small groups of guests were given personalized tours of the lab and chemistry demonstrations.  Following the tours and throughout the night members enjoyed drinks and hors d'oeuvres.
