Meet the Staff

The Joshua Wilderness Institute staff absolutely love the Lord, Joshua and investing in the students who attend.

Bob Plouffe


Bob was born and raised in central Massachusetts, just east of our Hume New England campus. Immediately following high school graduation, he left for the United States Air Force where he ended up serving a 25-year career spanning many states and career opportunities. After retiring from military life, Bob sensed a calling into full-time ministry. This calling brought him and his family to Hume Lake where he joined the team in the summer of 2003. Over the span of his Hume Lake career, Bob held such positions as Grant Writer, Development Manager, Marketing Director, and finally Human Resources Director where he's served since 2008. Associated with the Joshua Wilderness Institute (JWI) just a few years after its inception, Bob has become very familiar with the JWI program and its underpinnings. He understands and respects the roots of the program and supports its ideologies. The Plouffe family supported the JWI mentor program as "Pause" parents for eight years. Additionally, Bob accompanied the Joshua team on an Israel trip in 2010. In 2011, his son, Calen (now 25), graduated from JWI in the class of 2011. After graduation, Calen majored in Kinesiology at California Baptist University graduating in 2014. He is now a firefighter for Pasadena, CA. Calen is married to Kamee Clevenger, a school teacher, and they reside in Rancho Cucamonga, CA. Bob's wife, Debbie, is the 1st - 2nd Grade teacher for the Hume Lake Charter School and has been since their arrival in 2003. Bob and Debbie also have a daughter, Kayla (22), who also graduated from California Baptist University with a degree in Graphic Design and Photography. Kayla travels the globe shooting for different companies as a free-lance photographer. She resides in Newport Beach, CA. When Bob’s not driving a desk, you’ll find him outside either hiking, cycling, sketching, painting or reading stretched out in his hammock!
