Tammi Elizabeth Callahan (O'Halloran), formerly of Marshfield, went to Heaven unexpectedly on August 8, 2024. Tammi had a welcoming party of angels led by her son Sean O'Halloran, sister Sandra Carlson, brother Timmy Callahan, mother Dorothy Lord and father Tom Callahan. She leaves her brother Tom Callahan and his wife Lori (Brewster), brother Michael Callahan (Boston), sister Carrie Sylvester (Kingston), and nephew Randy Carlson and his wife Kim (Marston Mills) and niece Heidi Truitt (Marston Mills) as well as nieces, nephews, cousins, and newly found siblings and extended relatives from the Callahan and Szydlowski families.

Tammi had a life-long love for continuing her education and spending time near the beach. Cape Cod was a place that drew Tammi back many times living first in Sandwich and going as far as Orleans. Social media brought Tammi newfound connections to family and friends and deepened her connection to her alma mater Marshfield High School Class of 1979 in ways she probably never would have dreamed. Sean, her son and love of her life left this Earth and was a heartbreak that she would spend the next 9 years trying to mend and heal. The moment she entered Heaven all the pain and sorrow was replaced by total peace and love.

There will be a celebration of life service held at St. Ann's by the Sea Parish Church on Wednesday, September 4, 2024 at 10:00 a.m.. All are invited to attend and share the fellowship of healing. In lieu of flowers please make donations in Tammi and Sean's name to Hope Floats Healing and Wellness Center, by mail to 4 Elm St. Kingston, MA 02364 or online at https://www.hopefloatswellness.org/
