Daniel Parker Petrov

Daniel P. Petrov is Managing Shareholder of The Petrov Group Co., LPA. He represents employees, executives and people whose civil rights were violated in disputes before federal and state courts in Ohio and across the country. He has resolved claims of wrongful discharge, discrimination and retaliation under nearly every federal and state equal employment opportunity law.

He has obtained significant results for his clients, including a $28 million jury verdict in an age discrimination and retaliation case, a $6.7 million arbitration award in an age and disability discrimination case, and a $3 million judgment in a state retaliation case. Recent rulings in his cases include McFadden v. Charter Communications, 2024-Ohio-4564 (9th Dist.), holding that an employer’s blast email did not create an arbitration agreement; Wiertella v. Lake County, 141 F.4th 775 (6th Cir. 2025), denying qualified immunity to jail medical staff who withheld essential medication; and Kaplan v. Advanz Pharma Corp. (N.D. Ohio 2026), sending age and national origin discrimination claims to a jury. Prior results do not guarantee a similar outcome.

He negotiates and litigates executive employment agreements, noncompetition and nonsolicitation covenants, and confidentiality agreements.
