Dr. Vanessa Teresi

Dr. Teresi was born in Chicago, Illinois, and spent considerable amount of her youth split between Chicago and Argentina.

For her education, she attended college at the University of Massachusetts in Amherst, and then returned to the University of Illinois in Urbana to receive her Doctor of Veterinary Medicine degree. She has been in practice since 2004 and is internship trained.

Dr. Teresi enjoys treating dogs and cats with all conditions, but her special interests include: chronic skin and ear diseases, weight management, and striving for overall health and well-being.

Dr. Robert Merlo
Nov 7th, 1941 - Aug 14th, 2015

It is with great pride that I can say my father, Dr. Robert Merlo, has been my inspiration personally and professionally. His warmth and compassion for people and animals radiated from him. His ability to connect with people was immediate and powerful.

Most people who knew him would agree he was very infectious with his humor and his charismatic ways. He gave me the strength to be the woman I am today and I am so blessed to have shared our passion of veterinary medicine.

I am so grateful and honored that in the winter of his life, he helped establish my vision of Old Town Veterinary Hospital. It wouldn't have been the same without him. He touched the hearts of so many and inspire us all. I feel very fortunate that our team and many of our clients had the chance to get to know him and help keep the memories of him alive.
