APTS FOUNDERS
Alan El Tagi, B.C.B.A
Mr. El Tagi holds a Master’s Degree in Counseling Education from George Mason University and has developed a passion for reaching out to students with Autism Spectrum Disorder and other developmental disabilities.  He participated in the Special Olympics 1986 at Fort Lewis in Washington State while he was in the military, and from there, started working at (NVTC) Northern Virginia Training Center where he met his Co-Founder Susan Gross.  He became so interested in helping his clients become successful that he donated two years of his time to volunteer work while gaining experience working with some of the most intensive behaviors. In 1999 he went on to do consultation work in the community advising schools and parents on how to modify these behaviors.  He believes in intervention at an early age by setting expectations for success rather than waiting until the behavior is unmanageable or out of control.  Al has always been a visionary in the field of behavioral analysis and was among the first in the state of Virginia to become a Board Certified Behavior Analyst. Al’s partnership with Sue has allowed APTS to branch out and expand with the opening of a third APTS location and other global ventures.
Susan Gross, B.C.B.A.
Susan Gross brings to APTS over 30 years of experience in providing behavioral consultation, training, and support services to individuals with developmental and other disabilities.  She has provided professional support to their families/caregivers, and educators. She has developed her skills and career by working for various area programs as well as an independent behavior consultant.  She holds a Master’s Degree in Applied Behavioral Science from Adelphi University and was among one of the first Board Certified Behavior Analyst in the state of Virginia. After meeting her co-founder, Mr. El Tagi, at NVTC in 1992, she went on to work for the Phillips Program and became a Behavior Analyst, which eventually led to Susan becoming the head of the department. She and Mr. El Tagi met again and began doing In-Home Behavioral Consultation in order to help create a successful and manageable environment at home for students and parents. Sue remains passionate and dedicated to helping students with ASD and other developmental disabilities through Alternative Paths Training Schools’ program expansion in order to ensure long-term growth and sustainability for its clients, the company, and its vision.
