Dr. Espe got married!! Yep that’s right. She still goes by Dr Espe, but she does answer to Mrs. Hendrickson now too. Dr. Espe has several pets, including an adorable pug named “Teagan Violet Cherry Blossom”. She is the happiest little ball of enthusiasm you ever did meet. “Miss Teagan” enjoys tagging along with Dr. Espe and the hubby in the camper trailer and also hitching a ride on the kayak – of course she has her own spiffy life jacket! When Dr Espe is not busy camping or paddling she is an amazing gardener and the World’s Best Auntie to her awesome nephews and nieces.

Elizabeth Kraft, DVMBio Pic Beth

Elizabeth Kraft, DVM was born near Detroit Michigan. Raised as a city kid, she longed to be a farm kid. She transplanted with her family to North Dakota in 1994 and attended NDSU where she finished her undergraduate work and then moved on to Ames, Iowa to obtain her Doctor of Veterinary Medicine degree in 2000. Then she packed up and headed towards the west coast, where she had many adventures caring for large and small animals in the beautiful mountains of Southwestern Oregon, and married her sweet heart Herb. While in Oregon she started her own business, Kraft Mobile Veterinary Clinic. Twin boys and a little girl arrived soon after, bringing with them a whirlwind of adventure. Dr. Kraft came back to the Midwest in the summer of 2011 to be closer to family still in the central Dakota area. The mobile practice succeeded well in the Bismarck area, but Dr. Kraft felt the pull of family- raising three very active children and running a business was not an ideal situation. So she sold the mobile practice and joined Heart River Animal Hospital in August of 2015.

Dr. Kraft and her family enjoy camping, fishing, gardening and scouting. The family menagerie includes 2 cats (Carrots and Sugar), 1 teacup Coonhound (Libby), and 2 tortoises (Turbo and Milo).
