Operations Team:

Made up of Manufacturing, Quality Control, Quality Assurance, and Maintenance, the Puritan Products operations team is led by Tom Starner, Executive VP & Technical Director and Dave Girdler, VP of Operations. With over 100 years of combined chemical manufacturing experience, the operations management team allows Puritan to evaluate opportunities quickly and bring custom and new products to our customers very rapidly. This group brings to the table:

  • Glenn Coon, Director of Operations, with additional responsibility for the purchasing group, has 40+ years of experience in the specialty chemical industry. Glenn heads up a team consisting of a label and inventory control specialist, a distribution specialist, and a group of highly trained chemical operators with an average of 6 years manufacturing experience. This group works within and is trained under a high performance skills based work system where upward mobility is based on mastery of skills rather than length of service. It provides each operator with an opportunity to grow their skills and offers our customers a group of highly trained personnel to manufacture, package, and ship their orders.
  • A Quality Control Lab, led by Stephanie Pinho, Laboratory Manager, and staffed by chemists, all with a minimum of four-year degrees in the sciences and an average duration of service of 7 years.
  • Experienced Maintenance personnel, with an average of 11 years of service, have had a hand in building much of the plant equipment in-house.   This team is responsible for building and maintaining the plant equipment to meet the stringent standards required of our quality systems.

  • The sales side of the business is growing to facilitate our expansion in the various markets we serve.  Currently, Patrick Henry, Director of Business Development, and Torey Payne are canvassing the United States and beyond to meet with potential and existing customers in an effort to satisfy needs and solve problems.  In Ireland, John Geraghty, Director of Business Development, is focused on all of the biopharmaceutical companies who have set up shop there.  Patrick and John have a combined 50 years of experience in the chemical industry and in the pharma and biopharma industries.
