She is currently working on her certification for the Human Animal Bond. She is a USDA accredited veterinarian. Dr. Hummel has also received certification from Vet Stem in stem cell regenerative medicine. She is excited about the opportunities that integrative veterinary medicine can bring to her canine and feline patients.

When she is not working, she enjoys spending time chasing her daughter Quinn and being surrounded by her pets – especially her 140 lb bloodhound, Duke. She enjoys being active through training with camp gladiator and running terrain races with friends and family. She also enjoys the quieter side of yoga, reading & outdoor activities.
