Who Are We

Michael Smull, Partner

Michael Smull has been working with people with disabilities since 1972. His extensive experience covers nearly all aspects of developing community services. Michael is the Chair of The Learning Community for Person Centered Practices (TLC-PCP) and a senior partner in Support Development Associates (SDA). He is the co-developer of Essential Lifestyle Planning and has worked in 48 states and seven countries. He has helped found three (3) community agencies, assisted existing agencies with the conversion from programs to supports, and helped states, regions, and counties change their structures in order to support self-determination. He has helped people leave institutions in the US and the UK. 

Michael has written extensively on issues relating to supporting people with challenging behaviors, person centered planning, and the challenge of changing our system to one that will support self-determination. From 1982 through 1997 he worked at the University of Maryland.

When he left in 1997 he was a Research Assistant Professor with the Department of Counseling and Personnel Services at the College Park Campus and a Clinical Assistant Professor with the Department of Pediatrics at the University Of Maryland School of Medicine.

Michael and Mary Lou Bourne are the co-designers of efforts to develop person centered systems. His current efforts are focused on helping organizations and systems make the needed changes in skills, practices, and policies that result in supporting people to have self-directed lives. This work has taken place in over 50 agencies and 10 states. Mr. Smull is the recipient of the 2015 Compass Award from the National Association of Directors of Developmental Disabilities Services and the 2006 American Association on Intellectual and Developmental Disabilities service award. Michael lives in Annapolis, MD with his wife Andy and their four dogs.

Bob Sattler, Partner

Bob Sattler joined Support Development Associates in 2007 and became a Partner of the company in 2016.  Over the past 40 years his career has focused on building person centered community supports. He began his career as a direct support professional and early on redesigned HCBS residential programs that created opportunities for fewer people to live together. His career has allowed him to gain first-hand experience in primarily the I/DD system, ranging from creating supported employment programs as options to sheltered work, coordinating supports as a case manager, and focusing on administrative and executive roles at the county and state level.  This eventually led to establishing a service agency to support people with co-occurring needs (developmental disabilities and behavioral health challenges) to demonstrate how person centered practices could truly be provided within traditional Waiver funded structures and practices. 

Prior to joining SDA, he served as the Executive Director of the Provider Association in Colorado and worked closely with system stakeholders to improve services and supports for people, including the design of Self-Determination models. 

Mr. Sattler’s work has provided him unique opportunities to work and train in partnership with professionals from the fields of mental health, law enforcement and criminal justice, aging, vocational rehabilitation and state operated services in order to better support people with complex support needs. He currently consults across the nation to help people move to more community integrated settings and assist states and organizations with creating sustainable person centered systems and processes.  

Mr. Sattler is a Person Centered Thinking, People Planning Together and Person Centered Plan Facilitation Mentor Trainer through the Learning Community for Person Centered Practices and is a Charting the LifeCourse Ambassador.
