SAN FRANCISCO — Gryphon Investors announced that it has acquired Wittichen Supply Company. This represents the second investment closed by Gryphon’s Heritage Fund. Financial terms of the transaction were not disclosed.

 General Manager Charles Herring, who has been with Wittichen for 48 years, will become president of the company, and will continue to work closely with the existing management team.

 “Wittichen is a 100-year-old brand with a strong culture and exceptionally loyal employee and customer base,” said Craig Nikrant, Gryphon operating partner on the Heritage Fund Team. “We look forward to partnering and supporting the Wittichen management team in their next phase of growth by leveraging Gryphon’s in-house Operations Resource Group and Human Capital Team to enable further investment in its business and employees.”

 “We are excited to welcome and partner with the Gryphon team as we build on our recent growth and look to the future,” said Herring. “We are experiencing steady demand for product repair, maintenance, and improvement, and we expect that demand to continue in a post COVID-19 environment that is driving greater need for high-quality, safe air filtration. We look forward to servicing our existing and new customers with the same great team, supported by the added resources provided by our new partner.”

 “My goal is to leave the Company, our employees, customers, and suppliers in the best hands, and I feel confident that we have found the best partner in Gryphon,” said David Henderson, outgoing president of Wittichen. “Our business has been built on providing a premium service and customer experience and that will not change. Gryphon’s financial resources and operational know-how will be invaluable as Wittichen builds on its geographic expansion and continues to look for the most innovative ways to serve our loyal customers.”
