Rose E. Decosimo: A Trefoil Society Honoree

Trefoil Society Logo

The Trefoil Society Luncheon is a special event held each year where the community gathers to recognize a woman who has exemplified the mission of Girl Scouts throughout her life, living with courage, confidence, and character while making the world a better place. This August and September three luncheons will be held, each one organized by the Girl Scouts Council of Southern Appalachians’ (GSCSA) Philanthropy department. The final one takes place in Chattanooga, and our honoree is Rose E. Decosimo.

Rose E. Decosimo, a retired Elliott Davis Decosimo shareholder, practiced public accounting for almost thirty years. Her clients included public companies, not-for-profit organizations, and privately held businesses including financial institutions and manufacturers. Her firm’s dedication to community allowed her to serve on numerous civic boards throughout her career. Ms. Decosimo’s passion for community service was lit while volunteering in Girl Scouts and was modeled by her parents and grandmothers.

Ms. Decosimo began her professional career as a Registered Nurse in San Francisco after obtaining a Bachelor of Science degree in Nursing from the University of Tennessee at Knoxville. Upon her return to Chattanooga, she became a Hamilton County public health nurse. In this role she practiced “old timey” nursing, visiting patients in downtown housing units, the homeless, and the far reaches of Hamilton County. However, her accounting gene soon kicked in, and Ms. Decosimo obtained a Master of Business Administration degree with a concentration in accounting from the University of Tennessee at Chattanooga (UTC) while raising her young son, James Scott. She then joined Decosimo and Company, a firm founded by her father, Joseph Decosimo, which subsequently merged with Elliott Davis.

Ms. Decosimo has shared her expertise as a speaker by providing accounting and auditing updates, board governance guidance, and speaking about women’s roles in philanthropy.  Honors include recognition as the UTC Beta Alpha Psi Accountant of the Year and induction into United Way of Greater Chattanooga Leadership Hall of Fame.

In her retirement, Ms. Decosimo continues serving on numerous boards, helping to lead capital campaigns, and volunteering in her grandson’s elementary school. She is also learning to play the dulcimer, training her puppy, spending time with her family, and living life to the fullest.

“We are delighted Rose Decosimo is a Trefoil Society Honoree for 2019. Through her involvement in Girl Scouts, she learned leadership and the rewards that come through giving back to your community,” says Elizabeth Kramer, Vice President of Philanthropy. “She truly exemplifies what Girl Scouts values; a G.I.R.L.—go-getter, innovator, risk taker and leader.”

Join us from 11:30am-1:00pm on Tuesday, Sept. 17, at the Chattanooga Golf and Country Club, 1511 Riverview Rd, for a complimentary luncheon to honor Ms. Decosimo and support Girl Scouts, the premier leadership development organization for girls. To reserve your seat, contact Marguerite Hogan, Special Events and Campaign Manager at GSCSA, by phone at 800.474.1912 or email at
