Denise Sandifar


“My goal, no matter what my profession, has always been to be someone that people can turn to when they are facing a problem/challenge to provide guidance in finding a viable solution.”

Denise is the proud mother of two sons, Chris and Matt, and grandmother to three beautiful granddaughters, Lexi, Kenzi and Chloe.  She is a member the Tennessee Bar Association, Montgomery County Bar Association, the Lawyers’ Association for Women and the Tennessee Lawyers’ Association for Women. She is a former high school mathematics teacher in the Clarksville-Montgomery County School System.   Prior to her twelve-year tenure as a High School teacher she was an educator, administrator and women’s basketball coach at Oakland City University, in Oakland City, Indiana, for eleven years.

A woman of many talents, Denise has also maintained her Private Investigator’s license and has worked for a private investigation firm with offices in Clarksville, Chattanooga, Nashville, and Knoxville and owns a private investigations firm, FTS Investigations, which operates throughout the entire Middle Tennessee area, including Clarksville, Nashville, Murfreesboro, Chattanooga, and all surrounding areas.

Denise’s career goals have always revolved around making a difference in the lives of the people she works with and those career aspirations did not change when she entered the legal profession as an attorney.  In fact, that ideology might be enhanced even more as a result of being an attorney.  “People come to us at LSA from all different walks of life, with varied backgrounds, but they all come needing help with their individual problems and situations.  It is extremely gratifying knowing that I am in a position to be able to help them work through their issues.”
