Officials haven't said if his departure has anything to do with allegations filed against the shelter in December 2013.
Michael Lausen held the position of executive director for just over a year. The humane society is not commenting whether Lausen resigned or was fired.
A former employee filed a lawsuit late last year, claiming she was fired after refusing to sign a non-disclosure agreement.
The organizations Board of Directors is currently looking for a replacement for Lausen, and say they will continue to provide the best care for animals at the facility.
HSWC released a statement on Monday saying, "Michael Lausen is no longer the executive director of the Humane Society of Washington County, Maryland. We thank him for his services on behalf of the animals and wish him the best of luck on his endeavors.
The board of directors will be in the process of conducting a search for the next Executive Director. In the meantime our Director of Operations Ellen Taylor will be assuming the role of Interim Executive Director.
All of our staff and the board of Director of Humane Society of Washington County are committed to continuing our mission of providing the best care of the animals entrusted to us. We hope that you’ll continue to support us in that mission."
