Sia Yorker Brain Awareness Scholarship Foundation has first and foremost a very personal meaning to Deborah. Secondly, the foundation's efforts  have focused not just on acute brain hemorrhage and symptoms that leads to such, but also health awareness;  informing all  communities;  especially the communities that are most affected due to many underlying medical conditions, which can at times lead to  adverse brain conditions.  Finally the Foundation finds time to give tangibly back to the community through feeding the homeless, providing Christmas and Thanksgiving to families in need.  Serving as a board member of  Sia Yorker Brain Awareness Scholarship Foundation is indeed an honor.

Tiffanie Trent

Advisory Board Member

Sia Foundation

Tiffanie Trent is a dedicated mother and singled parent. Working in E-commerce she provides site management and customer service for three high end fashion brands. This keeps her quite busy, but she still finds time to give back to her family and community.

Although 19 years seemed like not enough time, Sia is living proof that “it’s not the years in your life that count, it’s the life in your years.” Sia lived a full life, but most importantly, a purposeful life. She made every day count and strove to be an example of Christ in everything she did. During those 19 years, she touched many lives including my own.


Sia Yorker, was more than a cousin to Tiffanie, she was a sister and best friend. Sia always brought joy to Tiffanie's heart, whether it was a phone call, one of their adventures, or even just a Facebook post. To know Sia Yorker was truly to love her. 


Tiffanie will be forever thankful for the memories and the bond the two shared. So, until the day Tiffanie and Sia get to see each other again, Tiffanie will honor Sia's life and memory by serving on the board of the Sia Yorker Brain Awareness Scholarship Foundation. By sharing Sia's story, we will continue to touch lives and raise awareness of this serious brain condition. Together we can make a difference.

A wife, mother, grand mother and Greenhouse Specialist, Lesly Yarde has remained a faithful, heart driven board member of Sia Yorker Brain Awareness Scholarship Foundation from it's conception. Lesly has always believed that God used the suddenly of Sia's transition due to a Sudden Acute Brain Hemorrhage to birth the foundation through her parents. There are so many that have been impacted by Sia's story, and have found strength to move forward in life because of God's strength that is seen in Sia's parents on a daily basis. Sia Yorker Brain Awareness Scholarship Foundation not only brings awareness to the community of Signs and Symptoms of adverse brain conditions, the involvement in the foundation gives one the courage to continue to move forward no matter the suddenlies of life. 


Not only have Sia's parents been dear friends to the Yarde family, they have also served as pastors, which continues to afford many the opportunity to witness God's Strength manifested in their life as they continue to walk out the suddenly of their precious Sia's transition.
