    We only met Dr. Koenig last week, and last night, we had to call to see if he would do a house-call to help our kitty cross over. Both he and his vet assistant came over, were so kind, and helped our little girl leave this earth in peace, grace and dignity. I can't thank them enough for this help and would highly recommend them for being your regular vet.

    Joy H.

    Nicole is the best. Great feedback and genuine care of her "Patients". Dr. Dave Koenig is a caring vet. Unlike some other vets who suck you dry financially, he provides viable options and let's you be involved in the process. He knows the pet is your "family". Highly recommend.

    Dr Koenig and his staff are great!!! They are caring and genuinely care about your fur babies. Our Ollie “the pooper dog” goes in regular for acupuncture for his back and the follow up and care for him is unsurpassed.❤️❤️
