We'd Like to Welcome You to Dead River Company

After thoughtfully considering who should continue to care for his customers, employees, and communities served, on December 7th, Matt Porter transferred ownership of Tidewater Oil to Dead River Company. Matt has graciously assisted the team during the transition. We thank him for his leadership over the years, and wish him the best.

Knowing Dead River Company's reputation for prompt, reliable, personalized service, the team at Tidewater Oil was excited to join the Dead River Company team. Together, we look forward to continuing to serve your heating needs.
