Melissa Ledford

Executive Assistant of Horse Operations

Melissa started her career with horses at a very young age growing up on a show & working cow horse ranch in Prosser, Washington.  As a child she competed horses in the show ring riding Western, English Pleasure and Equitation.   In addition, she had experience in hunter jumper competitions.  Melissa learned horsemanship and technique in the cutting and reining world.  She spent a year with a renowned reining and cutting horse trainer in Eastern Washington where she furthered her skills in that discipline.


She recounts starting her first horse under saddle when she was 10 years old and soon thereafter took on outside clients as a way to earn money while she was growing up.  In 2007 she helped a family friend start the training process for race horse babies and was asked to go to Emerald Downs to continue to help with the race horses. Working at Emerald Downs, Melissa was a groom and exercise rider where she was able to expand her knowledge base in the race horse industry learning from trainers, veterinarians and farriers alike.   Melissa’s career at Pegasus began in 2010 and she became assistant trainer in the fall of 2013.

Brennan Tweedy

Rehabilitation Manager

Brennan grew up in South Carolina, where she began riding and showing hunter jumpers at the age of five. A love of racehorses developed in 1982 after watching Gato Del Sol win the Kentucky Derby, and she knew that working with horses would be the best career for her. She continued to show horses on the East Coast until 1992 when she moved to the Pacific Northwest with her parents. Here she attended WSU, where she majored in Communications and foreign languages.


In 2002, Brennan received the opportunity to gallop racehorses at Emerald Downs for Aubrey Villyard  and his wife Sue. A great working relationship and friendship started, and together with Brennan’s husband Ben, they all bought eventual California Champion two-year-old Pirate’s Deputy at the Barrett’s Select Yearling Sale. Along with the Villyards at Emerald and Santa Anita, Brennan galloped for Mike Chambers, Frank Lucarelli, Jim Penney, and here at Pegasus. Her time at the track gave her invaluable experience as a groom, exercise rider, assistant trainer, and breaking babies. An injury in 2014 left her unable to ride, so she went to school for equine massage and physical therapy and switched gears to rehabilitation.


Along with her husband Ben, she has a four year old son Jack, a dog named Sherman and her horse Jebrica.
