Who We Are

Better Living Together (BLT) was founded in 2016 by Tim and Beate Sass, parents of an adult daughter who is living with a developmental disability. Our membership includes individuals with and without disabilities, caregivers, and organizations from throughout the Metro Atlanta area. BLT is dedicated to addressing the housing crisis facing people with intellectual and developmental disabilities (IDD) by facilitating the creation of accessible disability-inclusive communities. We are also leading advocacy efforts to influence policy changes that will enhance funding for affordable housing projects in Georgia that include individuals with IDD.

Our Leadership

Luke Arduino brings to the Board Members of Better Living Together both professional insight and lived experience to advance inclusive, accessible communities. Raised in Gwinnett County, Luke earned a degree in English from Georgia Gwinnett College and currently lives in downtown Atlanta.

As someone with cerebral palsy, Luke has a deep understanding of the supports, advocacy, and systems needed for people with disabilities to live independently and fully participate in their communities. He has served on Better Living Together’s Outreach Committee for over a year and is currently the researcher for the organization’s Housing Hub website project.

Luke is deeply committed to addressing housing accessibility and affordability as key pathways to independence, opportunity, and community inclusion for people with disabilities. When he is not advocating for disability rights, Luke enjoys immersing himself in mystery stories—an interest that sharpens his critical thinking and problem-solving skills, which he brings to his work in the real world.

Outside of his advocacy work, Luke is an avid pop culture enthusiast who enjoys watching a wide variety of genres. He’s especially drawn to mystery and thriller series, with favorites including PBS’s Astrid, Apple TV’s Slow Horses, and Netflix’s Hijack. Luke also enjoys cooking and food-focused shows such as The Great British Baking Show, along with high-energy dramas like The Night Agent. He also listens to a wide variety of podcasts, including The Popcast, which focuses on pop culture by breaking down movies, television, and celebrity news. Another favorite podcast is From the Front Porch, a book-centered podcast that explores new releases, classics, staff picks, and helps listeners discover their next great read. Luke enjoys staying active through swimming, walking, and biking.

Committee Chair for Partners and Communication

Harley grew up in northern Wisconsin, went to college at the University of Texas at Austin, and has called the Atlanta area home for nearly a dozen years. He started his career as a newspaper journalist, where he ended up writing a lot about this new thing called “the Internet,” back when this thing called the internet was a new thing. He segued into helping newspapers launch their own websites, which after a twist and turn or two, led him to help advertising agencies in Dallas and Atlanta build websites and expand their social media platforms. Harley is currently working as a user experience researcher at EY.

Harley’s expertise is in communications, so he will be assisting with the BLT website, email newsletters, and social media platforms.

Harley and his wife (a math tutor working with kids from 1st through 7th grade) moved to the Midway Woods neighborhood three-and-one-half years ago, which is when he first stumbled upon Legacy Park. Watching the developments there with keen interest, he responded to a Nextdoor posting from Beate, who was looking for help with Better Living Together’s communications.

Outside of work, he enjoys hiking, fly-fishing, and writing.

Beate Sass is the co-founder of Better Living Together (BLT). After a 30-year career as a physical therapist, Beate is now dedicating her efforts to facilitating the creation of disability-forward housing in Georgia.

After completing her advocacy training, Beate embarked on a two-year project entitled Real Stories Real People, which chronicled the lives and challenges of people with intellectual and developmental disabilities and their caregivers. She was moved by the stories shared by parents and their concerns and fears for the future of their adult children. Those stories fueled the inspiration for forming BLT. Beate is also a professional photographer and is dedicated to using her craft to highlight people’s stories in her community.

Tim Sass is a co-founder of Better Living Together and currently serves as the organization’s President. He recently retired from Georgia State University, where he was a Professor of Economics and the W.J. Usery Chair of the American Workplace.
