Wright, who has over 60 caps for Leinster, was recently voted the Unsung Hero by his fellow players at the IRUPA awards.
Alan Barron, Director of Rugby at the Suttonians, described the appointment as 'an illustration of the club's desire to develop the talents of young players who are coming through the ranks of the club's vast underage structure.'
Barron added: "Not only will the presence of Stan benefit existing players within the club, but, it will also attract new players, particularly forwards, which will no doubt improve and expand the game in our area."
Wright will be responsible not only for the coaching of the club's first team forwards, but also for developing the coaching structures in place for forwards from the minis and youths to the club's junior squads.
At present, Suttonians RFC field four senior age teams, an Under-20 side and also cater for players from under-6 to under-19.
