    Sherilyn Allen

    Sherilyn Allen, VMD, U of PA Vet 1974, founded Ironstone Veterinary Hospital in 1982. An equine practitioner for many years before establishing small animal veterinary hospitals in Lansdale, PA and then Boyertown, Dr. Allen also raised three children and engaged in breeding and showing of Neapolitan Mastiffs, and other dogs, horses, various farm animals species, and exotic birds, while managing and maintaining Ironstone Farm.

    Now that her children are grown and gone, when Dr. Allen is not in the clinic consulting and treating patients with allopathic or holistic methods, or doing specialty surgeries on the Mastiff breed dogs, she can usually be found on the back of a horse.

    Theresa Esbach
    Technician/Office Manager

    I have been a technician for over 15 years when I eagerly chose to make Ironstone Veterinary Hospital my home in 2004. I all enjoy all facets of this profession but I am truly passionate about dentistry and cold laser therapy. Working with a great team makes my job that much more enjoyable. When I am not at work I spend my free time taking my Doberman, Terra, for hikes, soaking up the sun or just snuggling on the sofa.

These are some pictures of the cows and goats that call Ironstone their home. They roam in the vast fields around the veterinary hospital.
