Theresa Rae Diefendorf
Berlin

Theresa Rae Diefendorf, age 62, passed away at her home on January 9, 2026. Born in New York City on March 10, 1963, she was the daughter of the late Stuart and Sheila (White) Canham.

A 1981 graduate of Elizabeth High School in Colorado, Theresa honorably served her country in the United States Army as an Administrative Specialist for six years. A proud veteran, she was a member of the American Legion Post #123 in Berlin.

Following her military service, Theresa built a successful career in finance and project management, including a tenure with Deutsche Bank in Baltimore. After relocating to Maryland in 2016, she transitioned into real estate, serving clients across Maryland and Delaware with several local firms, most recently Keller Williams. Known for her tireless work ethic and love of people, she also enjoyed connecting with her community through various part-time roles as a waitress, bartender, and Uber driver.

Theresa found great joy in life’s simple pleasures: tending to her yard, solving puzzles, reading, and dining out. She was particularly known for her talent in the kitchen, often baking treats to share with those around her. Above all, Theresa was a selfless friend and family member who could always be counted on to lend a helping hand, offer a warm meal, or provide a listening ear.

She is survived by her brothers, Pat (Kris) and Sean of Colorado, and Tim (Christine) of Maryland; her uncle, Art of Illinois; and a loving circle of nieces and nephews, including Natalie, Emma, Ryan (Danielle), and Riley, as well as her great-niece Teagan and great-nephew Cooper.

In accordance with her wishes, cremation has taken place, and no formal services are currently scheduled. The family is planning a Celebration of Life for June. Memories and condolences may be shared with the family through the Burbage Funeral Home website. Arrangements are being handled by The Burbage Funeral Home in Berlin.
