Meet The Staff

  • Claire Ainsworth
    Veterinarian, Owner

    Dr. Claire Ainsworth grew up in Lamont, Alberta, a small town not unlike Mayerthorpe.  Following in her dad’s footsteps…Claire always knew she would grow up to be a Veterinarian, and that mixed animal practice would be her focus.  She graduated from the Western College of Veterinary Medicine in 2005 and came to practice in Mayerthorpe that year.  It was here that Claire met her now husband Grant, with whom she has two boys, Carson and Jace.  In 2011 she, along with Janelle became owners of the practice. Since then she has strived to bring more advanced veterinary care to our rural community such as TPLO’s and fracture repair.   

  • Janelle Gauthier
    Veterinarian, Owner

    Dr. Janelle Gauthier, a Saskatchewan native from Birch Hills, graduated from the Western College of Veterinary Medicine in Saskatoon in 2006. She moved to Mayerthorpe shortly after and in 2011 became a practice owner along with Claire. She takes great pride in providing exemplary veterinary care to our rural community, whether it be personalized herd level care to our livestock producers, performing advanced orthopedic procedures on dogs and cats, and even integrating new therapies such as acupuncture. If she's not in the clinic, Janelle's probably out gardening or attempting to break the giant pumpkin record with her husband Cory, and two boys, Jack and Charlie. 

  • Sarah Wahlert
    Associate Veterinarian

    Dr. Sarah Wahlert graduated from the University of Minnesota College of Veterinary Medicine in 2013 at which time she moved to Canada to join our practice. Born and raised in Idaho and Montana, Sarah feels right at home in a small community like Mayerthorpe. Her areas of special interest are soft tissue surgery, equine and small animal dentistry, small ruminant herd health, camelid medicine, and even the occasional reptile or pet bird. To recharge, Sarah enjoys camping, paddle boarding, and traveling to new places with her dog, Tucker. 

  • Avril Sinclair
    Associate Veterinarian

    Dr. Avril Sinclair, a 2019 graduate of Western College of Veterinary Medicine, comes to us from Manitoba where she worked as an associate veterinarian at a rural mixed animal clinic. She appreciates the diversity that comes along with being a general practitioner in a small town clinic. Dr. Avril particularly enjoys surgery on both small and large animals, working with small ruminants, and anything 'gross'! She and her husband Wes love fishing, hunting, hiking, and spending time with their dogs Maggie and Thor, and their cats Oliver and Jack. Avril's other hobby is drinking coffee as much as possible which could explain her energetic personality! 

  • Carmen Astle
    Registered Veterinary Technologist

    Carmen Astle is our head RVT and has been a vital part of our team since graduating from NAIT in 2010. Born and raised in Whitecourt, Carmen has a special place in her heart for our clients and their pets. Her knowledge and enthusiasm for patient care and client education elevates the client experience to new levels. It’s rare to find a gem like her. She dedicates herself fully to ensuring that all your questions and concerns are addressed, and that your pet receives the best care possible (even coming into the clinic late at night to ensure your pet is tucked in). When not at work, she is a proud and dedicated aunt to her nephews SeVIIen and Nathan; and mom to her critters Fenton, Jitters, and Muffin.  

  • Madison Morgan
    Registered Veterinary Technologist

    Madison Morgan graduated as an RVT from NAIT in Edmonton in 2019 at which time she joined our team. She grew up in Blue Ridge and now lives in the Anselmo area with her husband Jared and their two dogs, Hades and Drake. Since joining our Hilltop family, Maddy has developed a feral cat obsession and is quickly mastering the art of cat whispering. Maddy’s eye for detail and patient comfort set her apart and make her a valuable asset to our team. 

  • Shanissa Lasher
    Registered Veterinary Technologist

    Shanissa is the newest member of our team and we are lucky to have her. After graduating from Olds College in spring of 2021 as an Animal Health Technologist, she returned home to Mayerthorpe and became part of our Hilltop family. When not busy at work, she enjoys riding horses, camping, gardening, and spending time with her dogs Gemma and Piper, and three-legged cat Elliot. 

  • Karen Disney

    Karen Disney has been part of the veterinary community for many years and joined our team as a receptionist in 2018.  Born and raised in Whitecourt, Karen is the one who seemingly has a connection with every client, even before they step through the doors!  Karen describes herself as someone who likes dry humour and dry wine, along with sunshine and good conversation. She is the proud mom of two kids, Myles and Daryn, and her dog Lynryd. 

  • Stewart The Clinic Cat
    Office Manager

    Stewart found his way to our clinic in 2012 as a stray, orphaned kitten from Fox Creek. Suffering from wounds and frost bite of his feet and tail, Stewart was hospitalized for treatment which included amputation of his tail. Having stolen a piece of our hearts, Stewart became part of our family and has evolved over the years into something like an annoying, grumpy brother. But we love him anyway.
