Teresa C. Douglas
BWMQ eTariff Manager and Office Administrator (1986-2026)
With great sadness, BWMQ announces the unexpected passing of our longtime colleague and friend, Teresa C. Douglas on June 6, 2026. Teresa was with Brown Williams Moorhead & Quinn Inc. since its inception in 1986 and was previously employed by the Federal Energy Regulatory Commission from 1982 to 1986 in the Office of Pipeline Producer Regulation.
Teresa was a highly valued member of our firm, known and appreciated for her commitment to our clients and determination to get things done right the first time.
Teresa’s kindness and thoughtfulness will be long remembered and deeply missed. Our thoughts and prayers go out to her family and loved ones during this time.
