A celebration of life for Green String Farm manager Thomas P. Graham will be held Sept. 14 in Santa Rosa.

A native of Concord, Mr. Graham died of a heart attack at his Sebastopol home on July 23, 2013. He was 54.

For many years, Mr. Graham was a certified purchasing agent who worked for companies including North Bay Rehabilitation Services, Palm Drive Hospital and Reach, the medical helicopter ambulance service.

He also worked for a time at Harmony Farm Supply in Sebastopol, from where he would bring home sick plants that he would nurse back to health in a special section of his garden.

Mr. Graham also worked as a bookseller, and later as a manager, for Copperfield's Books in Santa Rosa. In November, he took on the role of manager at Green String Farm in Petaluma.

"Thomas was such a great employee and manager," said Fred Cline, co-owner of Green String Farm. "He treated everyone with respect and had a gentle way about him. He helped us at the farm by being fully committed to its success and knew how to help our customers fully. He always had great ideas and was working on something new all the time. He is sorely missed and we strive to be like him."

He is survived by his wife, Mary Gannon Graham; children, Alison Graham of Santa Rosa, Christine Graham of San Francisco, and Patrick Graham of Alaska; siblings, Paul Graham of Danville and Anne Graham of Martinez. He was predeceased by his brother, John Graham.

Those planning to attend the celebration of life are asked to bring a dish to share, and wear a hat in Mr. Graham's honor.

Memorial donations may be made at Redwood Credit Union and directed to "Team Graham."
