Special Education Consultant, Paralegal

Jessica is a former special education attorney who spent her early career representing schools in due process hearings and on appeal. She most enjoyed working closely with educators on successfully implementing student services under the IDEA, Section 504, FERPA and HIPAA. After seeing the often negative results of litigation on educators, parents and students alike, she transitioned to a position with the United Way and worked in support of a Community School initiative. Most recently, Jessica worked at a small charter school in North Carolina where she experienced firsthand the power and challenges of fully including all students, regardless of differences. Jess truly understands the concerns of both schools and parents and takes a careful approach to facilitate communication.


A native of Pennsylvania, Jess’ family was thrilled to recently relocate to New Jersey after living away for more than seven years. When not supporting clients, Jess loves spending time with her family, exercising, reading and cooking.


Jessica Lenhart

Special Education Practice Leader

Diana is the practice leader in Posternock Apell’s Special Education practice. 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, combined with her 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 educational 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.
