About David
David Heller built a path to law that started in engineering and science. He earned a Bachelor of Science from Carnegie Mellon University in 1984, then pursued legal studies at Widener University Delaware School of Law, where he completed his J.D. His academic background combines technical training and legal education, a combination that has shaped the way he approaches matters in practice.
He is licensed to practice in Tennessee and has spent his professional career working in that jurisdiction. His name appears on the roster of attorneys associated with the firm Martin Heller Potempa & Sheppard, where he practices with colleagues who handle a range of legal matters. His work at that firm has involved client representation in the state where he is admitted to practice.
Colleagues describe Heller as steady and meticulous in his preparation. He favors clear, direct writing and careful attention to procedural detail. Those habits show up in client filings and court submissions. He moves deliberately through a case. He also spends time preparing witnesses and documents so that courtroom presentations are orderly and focused.
Over the years Heller has handled cases that required close analysis of facts and law. He draws on both his undergraduate training and his legal education when sorting technical evidence from legal argument. That background helps when complex details matter. He is comfortable working through dense material and translating it into positions that can be presented to a judge or opposing counsel.
Outside of the courtroom he maintains the steady routines of a practicing attorney. He meets with clients, coordinates discovery, and works with experts when specialized knowledge is needed. He is accustomed to negotiating agreements and shepherding matters toward resolution when circumstances allow. He also prepares litigation plans when cases move toward trial.
In his public and professional presence Heller opts for straightforward communication. He does not court publicity. He prefers to let case results and client relationships shape his reputation. His practice remains rooted in Tennessee courts and procedures.
As of 2026 he practices at Martin Heller Potempa & Sheppard and concentrates his practice on matters arising under Tennessee law.
