Former Executive

Beautiful Gate Center Board Member since January 2020. Shirley is an accomplished business professional with a keen interest in supporting the arts community, with a special emphasis on children’s programs, including those of differing abilities.

Her IBM 23-year management career was stellar in that she enjoyed every moment.  As a Senior Program Manager, she managed Software Developers designing and bringing to market advanced technology.  Throughout her career, Shirley developed creative approaches to resolving process inefficiencies, with a high point of developing the Business Case for bringing to market the IBM Fellow Touch Technology.  She was recognized for her accomplishment and assigned to oversee the Software Development Division incorporation of the Touch Technology into the OS2 Operating system and ensuring the Hardware Division in Japan was compatible.

Prior to retirement, as Manassas Choral Society President she noted conflicts with other organizations regarding scheduling.  Shirley founded the Cultural Arts Federation in Manassas, Va.  After retirement, she founded the Gig Harbor Key Peninsula Cultural Arts Commission in WA state.  These volunteer efforts brought the business community millions in business profits, but more importantly the overall community benefitted culturally from the various programs, e.g., Croatian Vella Luka Dancers, her Four Seasons program consisting of Spring Sing (Bands and Singers), Summer Dance (Cultural Dances), Autumn Sounds (Various Country instruments and their history) and Winter Visuals (arts of all mediums) and hundreds of community programs brought thousands of tourists and Hotel-Motel Tax income to the government coffers.

Retirement gave Shirley the opportunity to develop creative programs for her community benefiting artists, children and adults.  As a strong leader with excellent people skills, Shirley developed volunteer teams and together brought multitudes of programs to fruition. Her successes were built on a foundation and proven record of success and a determination to encourage her community to have access to the arts for all.  Shirley has lived in Summerville SC since 2008.

In 2018, she became a Summerville Noon Rotary Club member and was asked to be Secretary 2019-2020, 2020-2021 Vice President, and 2021-2022 President for over 103 membe3rs.  This opportunity has provided a multitude of business, government civic and community contacts which assist her endeavor to build a Cultural Arts Center which will provide, in addition to the norm, art-based programs for children and adults of differing abilities.

Shirley has extensive college education, first attending Community College.  IBM sponsored her college education to meet IBM position requirements.  She attended Princeton University, Georgetown University, George Mason University, George Washington, and Texas Western for IBM business related courses and certification.

Shirley is the widow of Anthony A. Berardo, entrepreneur.  Her two sons are her joy.  Arthur J. Kenney Jr., retired Army Chief Warrant 5 retired Helicopter Maintenance Test Pilot and Brigade Aviation Commander in Clarksville, TN. He is currently a Helicopter Pilot for a large Oil Company.  John W. Kenney, retired Coast Guard Lieutenant, now schedules Soccer for a South Carolina Region.  Shirley has four grandchildren – Grandson graduated the Coast Guard Academy, Granddaughters, one I the Air Force the other a nurse, and youngest grandson is a Citadel Junior.  She now has four great grandchildren – three great granddaughters (2 years old) and one great grandson (1 year old) with another great grandson due in June 2020.  To date she is blessed not to have a disabled family member.  However, she has minimal insight into the plight of the caretaker as her husband Anthony was in hospice eight months and she is aware of the feeling of imprisonment, excessive stress, watching someone suffer and not being able to relieve their pain.  Her heart is determined to provide for the lives of those affected with a sense of self and confidence through arts programming and give caretakers a peaceful respite.

Recently nominated and accepted into Marquis Who’sWho – Preeminent Publisher of Biographical Profiles Since 1898.  Her biography will appear in national communications and 2021-member catalog.  Shirley is a singer, published author and artist painting in both oil and watercolor, and enjoys crocheting afghans for family and non-profit fundraisers.
