Speaker Bio

Penny Williams is a leading parenting coach, author, and educator specializing in supporting families raising neurodivergent kids — those with ADHD, autism, anxiety, and other differences in how they think and process the world. She helps overwhelmed parents shift from frustration and overwhelm to peace, confidence, and connection, empowering them with science-backed strategies to foster their child’s success while honoring their unique needs.

As the award-winning author of four books on ADHD, including Boy Without Instructions, Penny has become a trusted voice in the neurodiverse parenting space. She is the host of the Beautifully Complex Podcast, a trusted resource with over 5 million downloads, where she shares expert insights and real-world strategies to help parents navigate the challenges and joys of raising neurodivergent kids.

Penny is also the founder of the Regulated Kids Project, a membership community providing practical, research-backed lessons, activities, and exercises for helping children build self-awareness, emotional regulation, and resilience. She co-created the Survival to Success Accelerator™, an innovative parent training program designed to transform how families understand and respond to behavior, replacing outdated discipline models with neuroscience-backed strategies rooted in compassion and connection.


Her work has been featured in leading publications such as ADDitude Magazine, Autism Parenting Magazine, and CHADD’s Attention Magazine, and she has been a sought-after speaker at international conferences.


At the heart of Penny’s work is a deep belief that every child deserves to feel seen, heard, and understood — and that parents have the power to create a home environment where their child’s differences are celebrated rather than battled. She has helped thousands of families worldwide move beyond survival mode, equipping them with the mindset, skills, and tools to thrive with their neurodivergent kids.
