Gillian Wainwright was born in London and lived in Italy and Belgium before moving to the United States. She became interested in painting in her teen-age years and went on to go to undergraduate school at the California College of Arts and Crafts. Later Gillian got her Masters degree in painting at the School of the Art Institute in Chicago, and since then has exhibited in numerous shows in New York City.

Having had cats all her life Gillian got her first dog, Henry, a French Bulldog with adorable green eyes (very rare), with her husband David. As a Christmas present to David she painted a portrait of Henry for him, which he treasures. The portrait holds a prominent place in their living room. This became the very first NYC Pet Portrait!

Since then, Gillian has created many more pet portraits to the delight of pet owners around the world. Gillian has a unique ability to capture the most beautiful moments for pet owners everywhere.
