On July 21, 2020, Rosemary, age 69 formerly of Pittsburgh, residing in Arizona returned to her Heavenly Home to be with her beloved husband and best friend of 50 years. Dr. Darrell Reed. Daughter of the late John and Mary Todroff. Loving mother of David (Juliya) Reed of WA. and Kristen (Thomas) Darby of AZ. Devoted grandmother of Katya and Andrew Reed and Aislyn Darby. Sister of Linda (late John) Elachko Jr.; Aunt of John (Nicole) Elachko III; Godmother to Betsy Lutmerding. Preceded in death by her aunts, uncles. Just as in life, Rosemary dedicated herself to loving and supporting her family at all times and through every moment. In pursuing her interests in molecular chemistry, she met her life companion, Darrell, and thus began a 50 year journey that included supporting him through his life, both professionally and at home, all the while raising two children, tending to the needs of her aunts, parents, and close friends. Professionally, Rosemary found her passion for finances, managing several private and non-profit organizations for over 30 years. This culminated in running Darrell’s medical practice until the day they retired. In the subsequent years, side by side with her devoted Darrell, she looked forward to her family visits with the grandchildren, the little getaway trips she and he shared, and simply enjoying the Arizona heat.
