Meet Charlie Cooper, @birchtechcorp's new Business Development Manager! We're excited to welcome Charlie Cooper to the Birchtech Corp. team.

That hands-on experience gives Charlie a real understanding of what small and rural water systems face every day: tight budgets, aging infrastructure, and new contaminant regulations that demand effective, affordable solutions. At Birchtech, Charlie will work with small and rural utilities nationwide to show how our water treatment solutions can help them meet those challenges with lower costs and greater operational efficiency.
