Our Staff

Carissa "C-Ram, Bing Bong" Ramseier

Certified Veterinary Technician/Food Guru/Flamingo

Carissa is originally from Augusta, WI.  After graduating from MATC (Madison Area Technical College) in 1996, she has worked as certified veterinary technician ever since.  Her favorite aspect of veterinary medicine is client education because she says she's getting to old to be a tech. She has been working up front in reception often as well, again, too old to tech. (#almost50) Carissa currently lives in Cadott, WI on a dairy farm with her husband and her three boys.  She shares her home with her dogs, Odette, and Elody as well as four cats, one rabbit, and like ten thousand chickens. 

You can easily find her by following the sound of the whistle, her laugh explosion, or by looking for the Royal Canin food order. 

Sue "Sue-Ba-Lou" Kohlhepp

Professional Groomer

Sue is originally from Eau Claire, WI.  She started grooming at the age of 14, volunteering 2 years to learn the trade.  She groomed in Rice Lake starting out and then was self employed for many years working out of her home.  In 1990 she moved to an Eau Claire veterinary clinic as their staff groomer.  She offers hand scissoring, stripping, working with hard to handle dogs and educating owners how to care for their pets at home.   Sue lives with her husband Chuck and her golden retrievers Crosby and Cheer.  They raise golden retrievers for conformation, showing, obedience, rally and AKC hunt testing.

Her favorite things to do outside of work include hiking, thrifting, and rewatching sitcoms.

She enjoys making questionable comments and running to the treatment room to crylaugh. Frequently asked to repeat the comments for maximum comedic effect.

CPDT-KA, Fear Free Certified, Certified Family Dog Mediator

Britni lives in Eau Claire with her dog Ruth. They enjoy taking walks and exploring their new digs. She also works part time at emBARK as a training assistant doing puppy classes, cooperative care, and enrichment activities. In the little bit of free time she has between dog stuff and more dog stuff, she enjoys loading Ruth into the car for a day trip hiking. 

She calls herself a social media manager (no one said so but no one specifically told her not to call herself that ). Pretends to do IT work with this website (haa). Probably grumpy. 

She's probably throwing snacks at someone. Or under the door.

Laurie graduated from MATC and became a CVT in 1999. She recently moved back to the area with her husband, Troy. She loves spending time with her horses, cats, dogs, family, and friends. She also enjoys starting horses and fostering kittens. She enjoys several outdoor activities, but also enjoys indoor activities such as cooking. She has special interests in dental procedures, lab work, and behavioral concerns in cats. Let's be honest. No one knows "Laurie," they know "Lawrence." Gives off big meow vibes.
