Dana Denise Harbour Mertz, 63, of Conroe, Texas, passed away on May 8, 2026.

She was born in Houston, Texas, on November 17, 1962, to John Thomas and Betty Jo Harbour. She fondly attended Broadway Baptist through high school before beginning her career at Maloney Pipeline, where she met her loving husband of 43 years, Douglas Mertz.

Dana was a strong and successful businesswoman who owned and operated her own company for the past 20 years. She was a devoted, wife, mother, daughter, sister, aunt, friend and "Gran." She never met a stranger, never took no for an answer, and loved her family fiercely.

She loved movies, dancing, crafting, decorating, gardening, and going on adventures with Dad. She found joy in the littlest things and brought warmth and laughter everywhere she went. She will be dearly missed by all who knew and loved her.

Dana was preceded in death by her parents, John Thomas Harbour Jr. and Betty Jo Sisson Harbour, as well as her loving in-laws, Eugene and Ann Mertz.

She is survived by her beloved husband, Douglas Mertz; her children, Logan Mertz and Reagan McCanna (husband, Kevin); her cherished grandchildren, Blair and Liam McCanna; and many loving family members and friends.
