Meet Our Team

Meet the special education lawyers and advocates who make up the Advo-Kids team.


Tracy Vargas

Tracy brings over 15 years of experience working with students in preschool through age 21. As a special education teacher and then administrator, she assisted in program development and trainings in all areas of special education, and has extensive experience with implementing school-wide positive behavior supports and with school transitions and post-secondary opportunities. She believes in a child-centered approach to education.  During her experience in the public education system, she became passionate about the applications of assistive technology in fostering student independence. She believes that, through assistive technologies, students can work alongside their peers with a variety of supports that are cost effective, individualized, and impactful on learning. In addition to identifying appropriate technologies based on student needs and training students in those technologies, Tracy has used her knowledge to better equip parents and her colleagues to support student learning. She is also certified by the State of New Jersey as a Supervisor and Teacher of the Handicapped.

Diana Sever, Esq.

Diana is our Special Education practice lead. Though she has close to 25 years of experience as a litigator and negotiator, her work in the field of Special Education is particularly important and fulfilling. As the mother of a child with special needs, Diana has experienced first hand the anxiety associated with being the parent of a student who requires additional or different resources.

It is Diana's unique perspective, her combination of litigation background and Special Education experience, which causes her to pursue a cooperative solution between the families she represents and their child's school whenever possible. Diana is a skilled litigator, and prepared to go to court when necessary. But she knows from experience that litigation is often expensive, unpredictable, and stressful - it is with this in mind that she helps families achieve their education goals for their children by bridging the gap between families and schools.  

Diana received her Juris Doctorate from Villanova University School of Law in 1994, and graduated Phi Beta Kappa and magna cum laude from the University of Delaware. She is licensed to practice law in the state and federal courts of New Jersey, and the 3rd Circuit United States Court of Appeals.
