A Stetson University College of Law graduate, Donald J. Kilfin built his career on a strong foundation in criminal law and procedure, evidence and trial advocacy. For six years, he served as a prosecutor with the Pinellas County State Attorney’s Office, gaining insight into how cases are charged, negotiated and tried. That experience now serves as a powerful advantage to clients seeking informed, strategic representation.

In 2013, he founded The Kilfin Law Firm, P.C., a full-service criminal defense practice based in St. Petersburg and serving the greater Tampa Bay area. The firm handles a wide range of criminal matters, from misdemeanors to murder, with a commitment to preparation, fairness and effective advocacy. His work reflects a simple guiding principle: justice is earned through diligence, respect for the process and the refusal to back down.

“I don’t measure my work in case numbers, but in lives affected. Criminal defense isn’t just practice—it’s responsibility,” Kilfin says.
