Attorney Profile

Gregory (Greg) P. Isaacs, graduated from The University of Tennessee College of Law in 1988. Mr. Isaacs founded The Isaacs Law Firm in 1993. The Isaacs Law Firm has maintained the highest professional ratings and levels of recognition by his peers, and most importantly his clients.

Mr. Isaacs has received the distinguished Martindale Hubble AV rating. This rating is based upon a stringent peer review process and signifies Mr. Isaacs as one who exemplifies highest ethical standards of the profession and as preeminent in field of criminal defense.

Mr. Isaacs has consistently received recognition by the most notable publications and societies including, but not limited to, Super Lawyers, Best Lawyers in America, CityView Top Attorneys, Knoxville Business Journal Top Attorney, and most recently has been recognized as one of the Top 100 Criminal Defense Lawyers by the National Trial Lawyers Association.  

The Isaacs Law Firm and its attorneys practice primarily in criminal defense litigation and personal injury cases in state and federal courts throughout Tennessee. Mr. Isaacs has successfully handled a number of high profile cases that have gained national attention, a few notable cases are set out below:

  • State v. Michael Frazier: Mr. Frazier’s case was one of the first Tennessee cases to be televised by Court TV. Mr. Frazier was a newspaper editor who was accused of attempting to murder the husband of a woman he profiled in a story and allegedly had an affair with. Mr. Isaacs successfully litigated the case, landing an impressive verdict of attempted manslaughter.
  • State v. Thomas “Zoo Man” Huskey: In this landmark case, Mr. Isaacs represented one of the most infamous alleged serial killers in recent Tennessee history. Thomas “The Zoo Man” Huskey stood trial for four capital homicides in addition to four counts of rape. The extensive litigation in this case gained significant national and international attention based on salient facts including Mr. Huskey’s multiple personalities and the fact that he was Knox County’s only reputed serial killer. After more than a decade of extensive litigation, Mr. Isaacs and the defense team were able to obtain two hung juries, and the murder charges against Mr. Huskey were ultimately dismissed.
  • State v. Kenneth “Kenny” Bartley: Kenny Bartley was a Campbell County youth who stood trial following a school shooting that resulted in the death of the school principal and injuries to two others. Bartley had initially pled guilty under the advice of his initial legal counsel, however, Mr. Isaacs was able to withdraw this plea and secure a new trial for Mr. Bartley. Following a jury trial, Mr. Isaacs secured a jury verdict of reckless homicide, resulting in Mr. Bartley’s release after serving eight years in custody.
  • Isaacs has also represented a number of prominent individuals within the Tennessee and Knoxville communities including local sheriffs and State Representatives. This representation has spanned various state and federal courts.
  • The Isaacs Law Firm has achieved numerous victories in both appellate and post-conviction cases. In State v. Phillip Pack, The Isaacs Law Firm successfully obtained release of Mr. Pack who had been convicted by a jury of murder. In a scathing appellate opinion, the Tennessee Court of Criminal Appeals reversed the conviction against Mr. Pack, noting the case was one in which there was “not a scintilla of evidence”.

Gregory P. Isaacs is also active within the community and has been a leader in many professional and civic organizations including but not limited to the following:

  • President of Knoxville Episcopal School
  • Board of Directors-Knoxville Zoo
  • Member-Tennessee Higher Education Commission
  • Adjunct Professor-University of Tennessee College of Law
  • Legal Analyst for WATE Channel 6-“Ask Isaacs” Weekly segment
