Derek Graham
Board Member
Early in his career, Derek was fortunate to get experience in civil litigation, business transactions and estate planning. Then in 2009, he and his wife had their first daughter who was born with Down syndrome. Like many of his clients today, they were inundated with information and felt overwhelmed. Nine years later, Derek now spends the majority of his days helping similarly situated families understand the various resources that exist. Derek finds it very rewarding to meet with families of all varieties and help them understand how to effectively and practically plan their estate. More than that though, he enjoys helping families understand the resources available to them and how to get the most out of those resources. His practice areas include Estate Planning, Special Needs Estate Planning, Developmental Disabilities Law, Elder Law, Guardianship, Probate, Probate Litigation and Business (organizational, transactional and succession). Derek earns his clients’ trust by working hard to accomplish their goals, being accessible and giving advice based upon experience.

Dianna Temple, OTD, OTR/L
Executive Director
Her SIB Jackie cannot talk, and they have always shared a connection through photography. In 2009 she made a documentary photography project of her sister’s day habilitation where she photographed her and her friends. From 2012-2017 she assisted Bowling Green photography students with a community collaboration where students partnered and photographed adults with disabilities. In 2020 she completed a portraiture project with a man that uses a power wheelchair. Together they made long-exposure photographs of his spinning wheelchair to promote visibility of disability. Dianna has also taught photography classes as a graduate student at the University of Missouri and as an adjunct for North Central State College.
During the pandemic, she moved with her husband Matt to be near her family on a small farm in Mansfield, Ohio. Working with Ohio SIBS is a dream job for her. She understands the importance of the sibling relationship and she is looking forward to advocating and supporting people with disabilities and their sisters and brothers.

Kelly Barnett
Board Member
She enjoyed that work immensely, which led her to pursue her masters degree in social work. During her MSW program she was lucky enough to find her mentor Dr. Tom Fish whose work involved siblings of individuals with disabilities. Kelly’s work with Dr, Fish provided her with the experience of facilitating groups for young siblings of individuals with disabilities. Throughout her career in behavior support services adult siblings have often been team members for her clients, serving in the role of advocate or guardian.
Kelly has been able to see many times the wonderful role siblings have in the life of their brother or sister with a developmental disability. Although Kelly does not have any family members with disabilities she does have a strong connection with her siblings, Kristen and Kacy. They are two of her biggest supporters and she cherishes those relationships.
While serving on the Ohio SIBS board she hopes to support siblings and help them to connect and gain knowledge that will help them support their sibling throughout their life.

Abby Turnwald
Secretary
During graduate school, Abby completed research on parental communication and sibling understanding of Angelman syndrome, a rare genetic disease. Her research detected a need for resources to answer siblings’ questions and facilitate discussion. Abby co-authored three books for siblings of individuals with Angelman syndrome. She wanted to extend her reach to other siblings, so she co-founded the organization Rare Sibling Stories.
In her free time, Abby enjoys hiking, biking, and kayaking! She joined the board in 2023. As an Ohio native, Abigail is excited about the opportunity to focus on siblings in our community.
