Caroline perlman

Caroline has had an ingrained passion for horses from the time she could walk. As a junior, Caroline earned her horse time as a groom and exercise rider, progressing through the years to eventually work for Canadian Team rider, Torchy Miller. Her Wall Street career afforded her the ability to purchase her own horses and she competed successfully for over 20 years in the top ranks as an Amateur in both the jumpers and the hunters. She has been privileged to work with many industry professionals and counts Harold Chopping and Brandie Holloway as her principal mentors who continue to guide her since turning professional.
