Derek Drennan has been a dedicated advocate for his clients for nearly 20 years. He has focused his practice in the defense of citizens accused of crimes both great and small.

He received his law degree from the Cumberland School of Law in May of 1996 and was admitted to the bar of the State of Alabama in September of that same year. While in law school, Drennan was employed as a law clerk with Doug Jones who would soon become the United States Attorney for the Northern District of Alabama and was subsequently elected United States Senator.
