Collingwood, ON: 
Tatham Engineering recently announced a series of appointments in their Collingwood, Bracebridge, Orillia, and Barrie offices that will strengthen their multi-disciplinary teams and support the continued growth of the company.

“These employees have proven themselves to be integral to our ongoing success. I am thrilled they will join us in leading Tatham’s future, and I have every confidence they will continue to make significant achievements as they transition into these new roles,” said Tatham’s Executive Vice President Bill Van Ryn.

In recent years, Tatham has experienced an increase in the need for their services, and their team has expanded quickly as a result. Tatham also acquired two consulting companies within the past two years and has added electrical, mechanical, air and noise, climate resilience, and hydrogeological departments and services.
