Life would lead him back to the beautiful San Joaquin Valley, however, and to the City of Shafter which he now calls home. Nick has been a resident in Kern County for nine years, where he found his calling in the Animal Control field.
In November of 2009, he accepted a position as an Animal Control Officer for the County of Kern.

This program consisted of public outreach to promote the importance of licensing and vaccinating pets as well as responsible pet ownership.
With a successful tenure as the “PEET” Officer, Nick ventured into field services which entailed responding to a variety of animal related issues. It was not until he began responding to reports of Animal Cruelty and seeing firsthand the kinds of terror that can be inflicted upon animals that he realized he had a golden opportunity to effect change, hold people accountable for their actions, and save lives. He carries this creed to whatever situation life presents and is steadfast in upholding these values for the citizens of this community.
In 2013, Nick accepted the position of Animal Control Manager for the City of Shafter, bringing with him the experience and understanding of community involvement and participation. This has resulted in an increase adoption levels and rescue live release rates of animals, while steadily maintaining increased animal intake numbers and calls for service.

This multi-pronged approach is accomplished partially with increased live release rates, carefully vetted rescue partners, and a thriving volunteer program.
