While attending Frederick Community College’s Veterinary Assistant program, Ian learned about A Cat Clinic and came to us to do a clinical internship for the program.  After he completed his internship, he joined our team as a part time Veterinary Assistant. Ian’s passion for cats stems from the time when, as a young boy, his mother surprised him with a little Bengal kitten.  She was wrapped in a pink blanket in a box, and he recalls her being so small and soft.  That was the start of his love for animals!  Currently, with his 2 brothers and 3 sisters, he shares Lila, a Plott Hound, at home.  His hobbies and interests include fantasy and science fiction, novels, video games, and of course, animals!
