Meet The Team
Owner & DVM
Dr. Katie Rein
I grew up on a ranch west of Melville, MT that has been in my family since 1893. After leaving home, I continued my education with college at Montana State University, veterinary school at Washington State University and an internship in Large Animal Medicine at Texas A&M University. After that I worked at Harlowton Veterinary Clinic for two years before starting Crazy Mountain Veterinary Service. It has been a joy for me to see Crazy Mountain Veterinary Service grow from me doing all the jobs to having a team of capable co-workers at various locations working together. Dividing the work among us all gives me time to do other things that I love: helping my husband, Jason Loose, on his ranch in Hobson; taking my boat to the lake; working on getting my private pilot’s license; an actual vacation now and then instead of just to go to conferences to get continuing education; working with the Montana Vet Med Association with a group called Power of Ten; and a governor appointed member of the Board of Veterinary Medicine.
Dr. Mandy Britt
I was born and raised in southwest Virginia. I have two brothers, one sister and twelve nieces and nephews. My faith and my family are very important to me. Throughout my childhood I was very involved in sports, 4-H, and church activities. I earned a B.S. in Biology at Winthrop University in South Carolina on a basketball scholarship and then continued my education at Virginia Tech earning my DVM in 2003. I’ve worked as a veterinarian in North Dakota, Virginia, and now Montana. Earlier in my career, I was fortunate enough to travel abroad with Christian Veterinary Mission, spending several weeks in Tanzania, Mongolia and Haiti and Zambia. I joined the CMVS team in 2016, and I’m so glad I did! It’s so refreshing to work with Dr. Katie and Dr. Becca and our wonderful support staff. Working as a mixed animal veterinarian has always been enjoyable to me and this practice gives me a chance to build on my previous experiences and keeps me challenged and always learning. There are no better people to work with than the awesome ranchers and pet owners that I get to serve. I love all the fun and rewarding opportunities I am able to be involved in here in WSS, including serving as coach of the Junior High Girl’s Basketball team and working with the Youth at the CMA Church. I recently became a new adoptive mom to my beautiful daughter Maxine. That journey has truly been life changing and enriching. In my time off I enjoy hanging out with my daughter, hiking, camping and just exploring all the cool things this area has to offer. Thanks so much for giving me the opportunity to serve!
Dr. Rebecca Gibbs
Becca Gibbs, DVM grew up in Three Forks MT on a commercial cow/calf operation. She graduated from Montana State University with a Bachelor’s in Animal and Range Sciences with a focus on livestock management. After attending Montana State, Dr. Gibbs attended Colorado State University College of Veterinary Medicine and graduated in 2019. Dr. Gibbs and Ruger, the guard dog to her vet mobile, joined CMVS in July of 2019. At CMVS Becca is a mixed animal practitioner and loves large animal emergency calls, especially a sheep call. Becca enjoys leather working, riding horses, doing all the ranch things and taste testing all the delectable food prepared by ranch wives. She feels blessed to be a part of an awesome team. She is also excited to continue serving the patients and clients at CMVS.
My name is Laurie and I am the practice manager for Crazy Mountain Vet Service. I started in 2015 as a part time vet assistant in White Sulphur Springs and worked through a couple different positions, eventually settling in my current job, working at both clinics, as well as remotely. I love my job, and the wide variety of responsibilities it holds. In a single day I can be taking vaccine orders, getting a workout on an equine lameness evaluation, or traveling to check in on either of the clinics.
When I started at CMVS, I was working on a degree in Early Childhood Education, and simply looking for a paying gig in White Sulphur Springs where I had followed my future husband to a new ranch job. Veterinary medicine had never crossed my mind as a career path, but am so thankful this is the one I stumbled on.
I grew up on ranches outside of Springdale, and moved to Big Timber when I was in high school. My family currently lives outside of Deer Lodge, on the beautiful Rock Creek Cattle Company Ranch, where my husband works. My family consists of myself, my husband Justin, our wild little girl, Ellie Ray, and our sweet son Tate. I have a lot of interests and hobbies, none of which I am particularly good at, but enjoy none the less. My main goal in life is to live in a way that would make my family proud, and have a good time while doing it!!
Born and raised in Judith Basin County Angela Green was very active in 4-H. She is a graduate of Stanford, high school that is! She earned her bachelor’s degree in finance at Montana State University-Billings. In 2014 she moved to Melville where she and her husband Neal operate Green Cattle Company, LLC and run yearlings through the summer.
Angela has been with CMVS for 7 years this June. Working as the the finance manager and inventory manager, she mainly works out of the Harlowton location but can be seen at WSS now and then too. Angela is currently the secretary and treasurer of the Sweet Grass County Farm Bureau Federation. She is also very active with the Crazy Peak Cattle Women supporting the local agriculture industry while helping provide local meat to Big Timber schools. In her free time she enjoys boating, camping, reading, sewing and spoiling her dogs Sadie and Maddy.
White Sulphur Springs Office Manager
I am Catalina, born and raised in Santiago, Chile. Spanish is my first language, so I apologize if I ask too many times to spell last names or words for me. I grew up going with my dad every weekend to ride horses and do Chilean rodeo. I taught horse back riding for 6 years.
Before moving full time to Montana I worked with a professional horse show jumper in Wellington, Florida. I traveled from there to Canada and Europe where I helped him get ready for shows.
I am a lucky to be married to Reed Brewer, and a proud mother of Thomas and Arlo, who hang out sometimes at the WSS office. My husband and I made a deal that when we got married we would get a horse for me and a boat for him. Three years later we have 3 horses and no boat!
In my time off I try to help at my parents-in laws' ranch, I am not much help but I enjoy the ride! Montana winters, especially in Ringling, are rough but the couple days we have sun are totally worth it. At CMVS I do whatever the vets need me to do!
Hi everyone, I am Carly! I grew up in eastern Montana on a registered black angus ranch, we sold out and then bought into commercial cattle. I graduated with an Equine studies degree in 2021 from Miles Community College. When I am not working I am spending time with my family, riding horses, hanging out with my dogs or helping out my boyfriend on his family's ranch. Thanks for giving me this opportunity to serve the community.
Jennifer Martin here, I get work at the WSS branch of CMVS. I work Wednesdays and do a little bit of everything here in Wilsall. I live in the Clyde Park area with my amazing family. My husband and I have two kids, Warren and Sadie. We have two Saint Bernards that we love dearly. We also have cats, chickens, guineas and ducks. I am originally from Washington State, but I am so thankful I moved out here and have been learning how to be a Montanan since 2011.
Hi everyone! I’m Emily--the latest addition to the CMVS team. I grew up in rural central Pennsylvania where I kept myself busy riding horses, raising sheep and goats, and practicing my favorite sport: pole vaulting! I earned a degree in Animal Science from Montana State before graduating from vet school at the University of Pennsylvania in 2020. This spring I married my now husband (Tucker) and moved up to White Sulphur Springs from Caldwell, ID, where I worked in a mixed practice that served the tri-state area of eastern Oregon, western Idaho and northern Nevada. We’re excited to be in the area and can’t wait to get to know everyone and their critters.
Tucker spends his summers in Gardiner, where he owns a fly fishing outfitter. Sometimes I talk him into taking me out on the boat during his time off so I can show him how not to cast a fly rod. I prefer to spend the rest of my free time doing just about anything outside: hiking, skiing, or enjoying some good food and cold beverages in the sunshine! You might see me running or driving around town with my trusty assistant, Clancy, who thinks he’s a tough cow dog but is much better at eating/rolling in their poop. I’m feeling very lucky be part of the CMVS crew and look forward to meeting you all!
Hey there! I am Karena (Robertson) Dale, your Harlo hometown girl. I am a Veterinary Assistant at Crazy Mountain Vet.
I was born in the Wheatland Memorial Hospital and was raised on my family's ranch north of town. It was there that I developed my love for animals. I especially like to take care of the bum lambs and calves.
A little fun fact about me is that I played trumpet in the Montana State University marching band. The band earned a trip to play in the Macy’s Day Parade in New York. While in New York, I was blown away by the aftermath of 9/11. It was November of 2001 and Ground Zero was still on fire. I decided that I needed to do something to help our country, so I joined the Navy. I was an Aviation Electrician on the MH-53E helicopters. I served for five years and then returned home.
I married my high school sweetheart, Fred Dale. Fred works for the Miller Ranch and we are raising cows and sheep on the Robertson ranch. Fred and I are blessed with an amazing family and great friends. My children are the highlight of my life. I absolutely adore them.
