Following a February protest outside of the Hawaiian Humane Society, the organization announced today that CEO Lisa Fowler is resigning immediately “for personal reasons.”

Some of the protesters singled out Fowler at the time and alleged that the Hawaiian Humane Society kills animals that are healthy or suffering from easily treatable conditions; violates standard safety procedures and labor practices; and has created a hostile work environment.

Fowler will remain on the payroll until April 30 to aid in the transition to new leadership, the Humane Society said in its announcement.

In the meantime, board chairman Bob Armstrong will serve as interim CEO.

“As board chair, I will step in as interim CEO while we conduct a national search for a new CEO,” Armstrong said in a statement. “Several board members will also be stepping in to offer support and guidance in key areas of our operations during the transition period.”

Following February’s protest, Armstrong said the organization would bring in a “third party” to assess whether the Humane Society was following euthanasia best practices.

“As announced earlier, while we believe the society has adhered to best practice euthanasia policies and procedures, we have initiated a third party assessment to ensure that we are operating at the highest level with regard to our euthanasia practices,” Armstrong said today. “We will keep you posted on our progress on this front.

On behalf of all you do to support animal welfare, we extend our deepest thanks. We could not fulfill our mission without you, and we are grateful for all that you do.”

Armstrong said there is no evidence of wrongdoing and stands behind the Humane Society’s policies.

Armstrong thanked Fowler for her eight years of service and said, “We appreciate her many contributions to the organization and her knowledge of animal welfare.”

Fowler said in her own statement that “It has been an honor and privilege to lead this great organization and to be part of the amazing welfare professionals who work there.”
