Aspen Pediatrics was founded in May of 1983. After Dr. Patrick Colletti finished his Navy obligation, he had always planned on practicing medicine in Reno, Nevada. He initially had an office by Renown Regional Medical Center (formerly Washoe Medical Center), but being confined in a big stuffy building was neither welcoming nor a conducive environment for himself or his patients. He wanted an office that looked and felt like a home, but would also provide the efficiency needed for a medical practice. Dr. Pat found a lot on Keystone Avenue, which was previously owned by the Audrain family. He hired Alan Ramsey to build this house-like medical office and it was completed in 1986. The layout was designed to have a friendly, non-threatening environment for children. The practice rests on the corner of Jones Street and Keystone Avenue and is a central location to the Greater Northern Nevada area.
