Ben Donoghue, Canine Behavior Consultant

On May 2, 1977, the soon to be bearded, Benjamin Paul Donoghue took his first breath.  In his younger years, growing up in the small New Hampshire town of Mason, Ben filled his days with exploring the outdoors capturing snakes, frogs, toads, and newts.  The arrivals of a brother(Sam), sister(Rebekah) springer spaniel(Addie) and a long haired white cat(Tuffy one) brought added fun to his outdoor adventures.  After ten years of small town livin the family moved to the big city (pop.100,000) of Manchester N.H.  After completing High School with O.K. grades Ben stayed in the Granite State to complete 5 years at the University of New Hampshire.  While attending this institute of higher education Ben frequented the famed White Mountains and the rocky shores of Maine all the while yearning for canine companionship.

In August of 2001 Ben hit the Long Trail of Vermont for reflection and to find direction.  The next three years of his life were filled with living and working outside with the Montana Conservation Corps and the Appalachian Mountain Club.  The last of these three years is what brought him to the Gallatin Valley and where he adopted his first dog Annay (Alaskan Husky) at the Gallatin Valley Humane Society (now Heart of the Valley Animal Shelter).  After a year or so of measly jobs to get by Ben applied to the organization where he found his beloved dog, for the often forgotten yet very important, position of Kennel Technician.  The benefits of helping animals and people in need has kept Ben hanging around.  “The feeling you get after watching the process of an animal arrive with no hope in their eyes, then begin to trust, and become confident, and then look into that adopters heart to find mutual understanding is priceless.”

Ben is currently 5’11” 175lbs.

He resides with his wife Kristen Wolf, a son Ezekiel Wolf Donoghue, three dogs Oly, Jedi, and Raven and cat Syrius.

Molly Cayer, Feline Technician

Molly has been an animal lover since the day she was born! She grew up in New Hampshire always having at least three animals in her home. She attended a boarding high school in beautiful Maine, then off to college in New Brunswick, Canada, and to another college in Oklahoma. Molly didn’t feel content where she was, so she decided she needed a change. She drove up to Montana to visit her brother, and like so many other Bozeman residents, Molly just couldn’t leave! She was employed by Heart of the Valley and was so excited. “Finally, I can put my love of animals to work!” She worked at the old shelter, trying to make the best of it for the animals in those poor living conditions. “It’s such a relief that now our dogs don’t have to sleep outside in our freezing winter nights.”

What Molly loves about Bozeman is the small town feel, breathtaking views, and all the wonderful hiking trails. She loves working at the shelter because “even though it can be emotionally difficult at times, it’s such a great feeling to see a dog or a cat get adopted into a new loving home.”

When not at work, Molly enjoys hiking, swimming, music, reading, biking, floating, and playing pool.

She resides in Bozeman with her best friend, Bart, a black lab she adopted from Heart of the Valley.

Lauren, Feline Technician

I am a native Montanan, born and raised in Bozeman and am the proud owner of two four-legged animals; Jaxyn a 7 year old female Jack Russell Terrier, and Howie a 2 year old Chihuahua/Jack Russell Terrier mix.  When I am not busy working or taking care of my four-legged animals, I enjoy spending time with family/friends, camping, softball, floating, crafts, and relaxing.

I feel right at home at Heart of the Valley, and truly enjoy making a difference in the lives of the animals each and every day.

Amber Lindner, Canine Technician

Born and raised here in the Gallatin valley I have had a strong bond with animals ever since I was a child. I have spent the last few years of my life traveling and exploring new things. After I graduated from BHS I moved to Minneapolis in 2013 to spend some time with my extended family. After some time there I made my way to Zambia, Africa where I spent three months doing an internship for my uncles organization. Now I am back in Bozeman going to MSU, so far I have been taking general courses but I am planning on declaring a psychology major this fall. I have volunteered at the Heart of the Valley for the past four years and I am so fortunate to now be able to spend my days taking care of animals as my full time job.

Roberta Theriault, Feline Technician

Before I joined the staff at Heart of the Valley, I was a volunteer for almost 2 years. I live in Bozeman and have loved animals all my life. I grew up in Massachusetts with 2 cats and a shepherd mix best friend named Chickee.   One of the first things I did at HOV as a volunteer was to become a foster mom to 4, one month old kittens, 2 of which became permanent kitties in my home living along side Shiloh, my HOV adopted Lab mix. Just this past December I adopted my latest cat, Hurley, now renamed Sammy after fostering him for a whole 2 days. When I’m not removing fur from all my dark clothing, I like to hike, camp, fly fish, eat chocolate and work on 2 children’s books that I am in the process of finishing.
