Diane Devanna
Berlin

Diane Devanna passed away at home on Saturday, Sept. 13, 2025, surrounded by her loving family after a courageous and enduring journey with cancer.

Born and raised in South Jersey, it was there she met her husband, Gary, while working together. They married in September 1979 and in 1985, started a family HVAC business together, Gary’s Shore Service. Diane was the backbone of the business and the household, acting as both Office Manager and Treasurer while also raising their son.

In 2009, Diane and Gary relocated to Berlin, Maryland, where they reestablished the family business.

Diagnosed with cancer in 2011, Diane faced her illness with remarkable strength and resilience. Throughout her journey, she was surrounded by an extraordinary support group of friends who became like family. Diane was known for her love of cats, her appreciation of a good margarita, and the joy she found in spending time with friends and family. You could also always count on Diane to give the best hugs.

Diane is survived by her devoted husband of 45 years, Gary, who considers himself the luckiest man alive to have shared his life with her; her son Bob (Tory); her grandson Declan; her mother Peg; her sister Donna (Steve); nephews Chris (Kate) and Matt (Rebecca); her brother-in-law Fred (Jackie); nephew Dave (Christine) and niece Laura (Henry) as well as  their mother, Patty (Rick). She was predeceased by her infant son Gary Jr. and her father Bob.

Per Diane’s wishes, there will not be a formal service. A celebration of her life will be held at a later date, during the warm weather months she loved most—she never liked the cold!

In lieu of flowers, donations may be made in Diane’s honor to Town Cats of Ocean City, Maryland at PO Box 1405, Ocean Pines, Md. 21811.
