Schuck and the board of Eastside Boxing deny the allegations.
"The recent events have been precipitated by the malicious actions of a select few who — in the wake of failed attempts to further their own interests — are attempting to destroy a gym with a longstanding history of excellence, perseverance, diversity and generosity," they responded in a 31-page written statement emailed to CBC News .
The document includes nearly 50 statements of support for Schuck and the club from male and female members, coaches and staff.
Schuck and the club's board have labelled Jaime Ward-Yassin, a former manager, coach and board member, as the ringleader behind the accusations. Ward-Yassin, a former pro boxer, was the head of the women's programs at Eastside Boxing. She is also Schuck's ex-wife.
