Jeff Rosenthal, DVM

Chief Executive Officer

2023 marks Jeff’s 23rd year with the Idaho Humane Society. After graduating from Washington State University College of Veterinary Medicine, he practiced as a small animal practitioner in Southern Oregon for 7 years prior to becoming Medical Director for the IHS’s Veterinary Medical Center in 2000. In 2002, he transitioned to become the Chief Executive Officer of IHS.

During his time in leadership, the organization has seen dramatic improvement in the save rate for sheltered pets alongside the creation of innovative programs such as our correctional facility-based dog training program, expansion of spay and neuter efforts, our Pet Food Pantry, and the expansion of full-service low-cost veterinary care for public clients. The number of employees has more than doubled, and he oversaw a successful 16 million dollar Capital Campaign to complete our new Adoption, Veterinary Medical, and Humane Education Centers. He is also credited for significant improvements to Idaho’s animal welfare laws including a crucial law providing for the forfeiture of abused animals from those who treat them with neglect or cruelty, a felony animal fighting statute, and the State’s at-risk and dangerous dog statute.

An unusual feature of his role at the Idaho Humane Society comes from a career-long interest and extensive training in veterinary orthopedic surgery. In addition to fulfilling all the responsibilities of CEO, each and every week Jeff continues to provide advanced orthopedic procedures for shelter and publicly owned pets. This expertise within an animal shelter is unique and allows us to restore pain-free mobility to hundreds of pets each year.

Jeff’s family moved to Boise in 1980, and he was excited to return to our community. His entire immediate family lives in Boise.

Director of Development and Stewardship

Leah Stephens Clark joins the Idaho Humane Society with a background in education, the arts, and nonprofits. A native of Boise, Leah’s fondness for the city she calls home is profound and her love of the community is clear to those who meet her. One of the things she loves about development work is meeting new people and learning how IHS has impacted their lives. There are so many great stories to tell! She is grateful for a work-life balance that allows her to spend time in her 1979 Dodge Transvan (jealous?), teaching dance, and planting in her garden. She has two cats, Benjamin and Mae Mobley, and a dog named Julian who were all adopted from the Idaho Humane Society over the years. Her pets bring her almost as much joy as her children, Rafferty and Matilde.

Idaho Humane Society

Craig Nixon

Animal Control Director

Craig moved to Idaho to attend The College of Idaho to continue his college education and pursue playing collegiate baseball. It did not take long until he realized that this move to Idaho from California would change his outlook on life and his appreciation for what Idaho has to offer.

In April 2023, Craig joined the Idaho Humane Society as the Director of Animal Care and Control. Soon thereafter, Craig retired from the Boise Police Department after serving the Boise community for 25 years. During that time, Craig held several positions within BPD, but ended his career as a Sergeant for the Bike Patrol Unit and as one of the last remaining original members of the Boise Police Honor Guard – two of the most rewarding duties held during his law enforcement career. The transition from the Boise Police Department to the Idaho Humane Society has also been worthwhile, as it has allowed Craig to combine his experience in law enforcement with his love for animals.

Craig has two pets – Kali who was adopted from IHS in 2016, and a cat named Cleo. When not working, Craig enjoys spending time with his wife and family, traveling, and playing golf (even on bad days).

While she recently joined the team at Idaho Humane, she is looking forward to working with such a committed and progressive organization.

Laura loves working with people daily in her role as the Volunteer Manager. It’s especially rewarding for her to see animals connected to their forever homes. She is a big believer in rescue.
