9901 Belward Campus Drive #100

Rockville, MD 208503017627323


"I have always known that I have a passion for teaching and helping others," says Jill Broder, whose 30 years of experience in education are a testament to just how serious this mission is to her. While passion for her work is the driving force behind her endeavors, Jill has the credentials to show for it as well. She received her undergraduate degree from the University of Maryland as a Bachelor of Science in Special Education, and then proceeded to earn a Master of Education Degree with a focus in Remedial Reading and Math, specializing in education for the gifted and talented. As a professional educator today, Jill continues to work with students who have learning disabilities, executive functioning issues, and Attention Deficit Hyperactive Disorder (ADHD).Jill's commitment to education is deeply rooted in personal history and fueled by the motivation to improve the learning of those around her. She was set firmly on her career path at an early age, when her brother, then a third-grader, was diagnosed with dyslexia and attention deficit hyperactive disorder. "My mother’s main objective," Jill recalls, "was to ensure that his optimism, his zest for life, and his overall positive demeanor were not negatively affected by this diagnosis." Jill's interest was sparked as she watched her brother thrive under proper guidance, but none inspired her more than his wonderful tutor. "I knew that I needed to make this my life's work," Jill explains. "I wanted to expand on her ideas and bring this type of success to as many students as I possibly could."The year 1981 marked the opening of her first tutoring center, dedicated to helping the gifted and talented as well as students with learning differences. Over two decades later, Jill has remained steadfast in her cause, now providing tutoring services for learners of all levels and ages, ranging anywhere from preschool to college. In 2011, she founded the Jill Broder Education Group to support schools in their programming options. Drawing on her expertise and experience, she assembled a highly qualified staff to operate within existing school curriculums, working with administrators to help develop their staff, with students to facilitate preparation for standardized testing, and even with parents, educating them about programs to help their children make the most of their time at school.

Licensed Psychologist

Address: office 1: 26601 Clarksburg Road Damascus, Md. 20872


Email: And

Dr. Elizabeth Tsakiris specializes in psychological assessment, research, therapy and intervention services for families and their children with complex behavior and developmental challenges. For the last 10 years, she has provided expert psychological and consultation services for unique students to school systems across the east coast. Her psychological skills are augmented by a special education degree, and 17 years of teaching in hospital/ residential settings, as well as self-contained and inclusive classrooms settings. After 33 years in Montgomery County Public Schools, she will be opening her private practice in spring 2013. Over her career, Liz has worked to integrate neuropsychological constructs, affect development with learning and behavioral theories for children with complex profiles across clinic, school and home. Traditional learning and developmental trajectories assume relatively intact vocal, hearing, vision, movement, cognition and physiological health. Dr. Tsakiris’ specialized assessment and interventions emphasize discovery, acquisition and demonstration of relationship and learning competencies for children with autism and multiple disabilities that don’t always fit this trajectory. Consultation with schools and families incorporates understanding how such children “show what they know” along a unique, individual format, as opposed to forcing them into a more traditional one where they can’t grow and learn as easily or joyfully. These efforts include modifying psychological assessments to better understand how the most challenged children learn and relate, followed by development of appropriate educational and behavioral interventions accordingly. Using a hands-on approach in the “real time” of school and home, she works with parents and teachers to help develop teaching and behavior strategies unique to the multiple needs of each child. Her interventions incorporate current research in neurology, psychology and education—with an emphasis on compassion and creativity that helps parents, teachers, and children thrive. Publications include a chapter in ICDL Clinical Practice Guidelines (2002) on Evaluating Intervention Effectiveness in Autism- Clinically Significant or Clinically Meaningful? In 2009 she completed the first retrospective outcome study comparing 30 children who completed intensive ABA and DIR programs in Treatment Effectiveness in Preschool Autism – A Look at Affective Variables- earning first place in Behavior and the Mind Graduate Research competition in the state of Maryland. Last year she authored a chapter on working with teachers of severely challenged students in Becoming a School Consultant: Lessons Learned, edited by Dr. Sylvia Rosenfield. Whether in research, assessment, or intervention, Dr. Tsakiris is committed to extending the reach of the medical, psychological, and educational community to the most significantly challenged children and their families.
