Lu Grant

Staff & Board Member

Lu is a lifetime resident of Simpsonville South Carolina.   After graduating from Mauldin High school, she studied Special Education at the University of South Carolina Spartanburg.    She received specialized training in Autism, working for a replication site under Dr. Michael Wolfe, a student of Dr. Ivor Lovass’s 1985 study on the effects of Applied Behavior Analysis and the impact of treatment on those on the Autism Spectrum.  She has given most of her professional career to advancing therapies and therapeutic interventions that can have a positive impact on those diagnosed with an Autism spectrum disorder.

Lu’s devotion to Special Education began as a child, with an older sister with Special Needs.  She witnessed first hand her parents’ determination to make her sister’s life one of joy and purpose.   She became a fierce advocate for those who often were left behind due to a diagnosis or mis-diagnosis.  Her life experiences helped fuel Lu’s true passion.

In 2015, Lu began the Little White House to serve a growing gap in services in Upstate South Carolina. Its purpose is to provide a Skill Building Center for those diagnosed on the Autism Spectrum.  She is passionate about providing a “personal” approach to helping those families effected by Autism. She continues to create programs for her clients and provide them with life experiences that otherwise they may not have, such as participating in horseback riding, art, and life skill integration – with a goal of normalizing and de-stigmatizing Autism.

Nikki Bailey

Board Member

Nikki Bailey is joining our team by coming along side our special needs families with compassion and experience. Nikki has a background in emergency medicine while in her home state of Ohio. The Bailey family moved to the Upstate area in 2011. Her oldest daughter was then diagnosed with Autism in 2012, thus changing Nikki’s career path into family support for special needs families. Since then she has helped the community in a diverse variety of support and advocacy. 

Nikki has worked as an Office Administrator/Patient Advocate for 2 pediatric clinics in the upstate over the last 7 years. This role allowed her to assist and encourage families. Nikki has a gift of helping families navigate from evaluations, paperwork, approvals, diagnosis, treatment and medical care/support assistance. Helping families understand the sometimes-overwhelming processes can help them approach this path with more clarity and understanding, thus being able to help their child succeed. 

Physical empowerment is also vital to helping the participants achieve their personal greatness. Nikki gets to help them achieve these goals by coaching the Special Olympics powerlifting team at Tri-fit Barbell in Mauldin.  

She is very excited for this opportunity to serve on the board, bringing passion and commitment to helping our families.
