The House of Flowers was begun in the summer of 1949 by Isabel O'Neill and her Aunt Ceil Gillespie. Isabel operated the shop until 1972 when it was purchased by her second cousin Michael O'Neill and his mother Marjorie.

Colleen began her business career operating her own hairdressing business for 26 years. Her lifelong interest in interior design, coupled with working part time in her brother's shop, motivated her to give up her business and dive head first into the floral world.

Since then she has pursued her floral design education with great intensity, studying with several top educators from Germany, California and Vancouver. She also attends the American Institute of Floral Designers National Symposium each year, which is held somewhere different each years. Colleen also volunteers to make designs with left over flowers at the convention with AIFD "Bloom Over" where hundreds of floral designs from the symposium are delivered to hospitals and hospices all over the host city.

Colleen has worked as an assistant with the Philadelphia Flower Show, where she designed for the show. She was co-chairman for the AIFD exhibit at the 2007 show. Colleen will be the chair person for the 2008 AIFD exhibit. Titled "Jazz it Up". She is also the secretary for the Northeast Region of AIFD.
