TnT Racing has been a Maryland based racing stable for over 25 years. Trainer Lori Testerman was honored with the Most Outstanding Trainer award in 2001. She is the first woman in Maryland's history to achieve this award.

Lori Testerman was a Pimlico based trainer for more than 25 years. She is now based at Laurel Race Track. She served on the MTHA board of directors from 2002 to 2008. The MTHA honored Ms. Testerman as MARYLANDS OUTSANDING TRAINER in 2001, the season in which she reached new career heights with graded stakes winning sprint star Disco Rico. She is the first woman to receive this award. A native of Lutherville Md., Ms. Testerman began working on the race track at age 16-sneaking into Timonium before school-and never pursued any line of work except horses. She served as stable foreman for trainer Charlie Lewis at Three Cousins Farm in the 1980s, and spent 12 years as a resident trainer at Nancy Stauberg's Harford Hill Farm. Ms. Testerman was married for 22 years to David Testerman, a former jockey who died in 2001. She has a son David  and a daughter Carli
