Greylock Federal Credit Union CEO Angelo Stracuzzi has resigned, weeks after the credit union’s board learned of his misdemeanor assault conviction.

The credit union said Marilyn Sperling, a 25-year veteran of the Greylock, will serve as interim president and CEO.

Stracuzzi was arrested in 2004 and convicted of assault and criminal mischief in 2005 following an incident involving a minor, Banker & Tradesman reported this week. The credit union’s board of directors learned about Stracuzzi’s conviction in late May and initiated an "evaluation", according to a statement.

Sperling has been Greylock’s senior vice president for the past seven years.

Here is Greylock’s full statement on the matter:

"We have accepted the resignation of President and CEO Angelo Stracuzzi. This concludes a full evaluation that began in late May 2010 when this Board of Directors first learned of Angelo Stracuzzi’s 2005 misdemeanor conviction."

"In accordance with our established succession plan, the Greylock Directors convened a special Board meeting and appointed long time executive Marilyn Sperling as Interim President and CEO.    Marilyn has 35 years of banking experience including 25 years here at Greylock.  Marilyn and the other members of Greylock’s senior management team have taken all steps needed to ensure a seamless transition with no disruption of service."

"Marilyn built our mortgage practice from a small department on Kellogg Street to the premiere real estate lending team in Western Massachusetts.  She has also shaped the most successful sales and service culture of any financial institution in Berkshire County.  In addition, for the past seven years as Senior Vice President, she has been responsible for our entire branch network. We have full confidence in Marilyn Sperling’s ability to lead this senior management team and all of our employees in maintaining Greylock’s standards of excellence."

Board Chairperson Sheila LaBarbera added: "Our established succession plan called for Marilyn Sperling to step in as interim President and CEO, and she is well prepared for the position.  During her 25-year career with Greylock, she has played a leadership role in nearly every facet of our business. She is strongly supported by an outstanding senior management team which collectively offers more than 300 years of banking experience.

Chairperson LaBarbera added: "In tendering his resignation, Angelo stated that he felt this was in the best interest of the credit union. We’ll always appreciate the achievements of the credit union under his leadership."
