Tristan lives and trains in Norfolk under Olympic carriage driver, John Parker. He is currently looking after 24 horses, and has been driving carriages since he was eleven. He also makes and mends harnesses and is qualified to teach children how to ride.
Until he found a job which allowed him to work with horses, Tristan wanted to be an Air Force pilot. He is still a part time Air Force Cadet. His parents live in Germany and his father works in off-shore oil.
Tristan has driven a variety of horse-drawn vehicles and is knowledgeable
about the landau, the brougham, the wagonette and the dog cart that are housed
at Manderston and that he uses to transport the Olliff-Coopers on their social
round. His role also involves teaching Master Guy and Mr Jonathan equestrian skills.
The Rule Book states: "As the Coachman/Groom you are the only outdoor member of
Staff on the estate, and as such you will not live in the main house, but
have accommodation above the stables. You will however take your meals in
the Servants' Hall with the other House Servants. You have sole charge of
three horses and a pony and an assortment of carriages. Although your duties
do not fall into their departments, you answer to the butler and housekeeper and should expect to take orders from them.
