Mark was formerly strength and fitness coach with Wasps but made the trip north this summer to take up a new challenge at Glasgow.
In this month's copy of Rugby World, Mark talks to Richard Bath about the 'fantastic challenge' that brought him north.
"Glasgow have a group of players who are tremendously dedicated and desperate to know what they've got to do to succeed," says Mark.
Mark has been impressed with the work ethic of the Glasgow players but adds: "It'll be interesting to see whether that's sustained when the rain is lashing down in January."
Mark is 25 and originally from Wigan. For one so young, he has some impressive names on his CV. Prior to his time with Wasps he worked with Bolton Wanderers, the English lacrosse team, Superbowl winners Tampa Bay Buccaneers and the Olympic Medical Centre.
When asked what differences there are between the players at Wasps and his new charges at Glasgow, Mark says: "The lads at Glasgow are all what I'd call 'running fit'. But the challenge lies in getting their physicality and collision skills up to the sort of levels you would find at Wasps.
"It's not something that happens overnight because getting on the weights is something you need a full pre-season to do and I arrived halfway through the summer. But we'll work on it and get there because it's the vital area.
"The game is getting increasingly confrontational and if your side is a little bit smaller than some, you've got to punch your weight."
Mark is currently using drills based around tackling pads, bodysuits and shields to work on collision based skills as well as a range of wrestling contests.
Mark believes that in young forwards like Euan Murray, John Beattie and John Barclay, and backs like Sean Lamont and Graeme Morrison, who he described as a 'monster', among others, he believes he has players to match their southern counterparts.
Mark's arrival will mean a lot of hard work for the Glasgow players, but we look forward to seeing the fruits of his, and their labour.
