Catherina O'Neil Founder

Catherina O'Neil is Trevor's wife, and founded Colonial in 1992.  She has always had a passion for helping seniors and an entrepreneurial spirit, and becoming a provider of in-home care services was a natural fit for her.  The principles on which Catherina began Colonial are very prevalent today - to recruit and retain the best Home Care Aides, provide top-notch customer service, and treat each client as family.  At home, Catherina often volunteers at her sons'  school, and enjoys travel and family gatherings.

Nancy San Miguel Client Services Manager & Personnel Supervisor

Nancy has been with Colonial Home Care since 1999, which is longer than most home care companies have even been in business.  As Colonial's Client Services Manager, she is responsible for general oversight of the service process, managing client schedules, and staffing employees including Home Care Aide recruitment and supervision.  Nancy also performs the initial client assessment and evaluation. Nancy is the proud mother of 3 teenage children, 2 daughters and 1 son.  She and her husband enjoy spending time with their family and helping their children with numerous extra-curricular and volunteer activities.
