Who We Are

Colonial Home Care has been established longer than any other privately owned and operated home care company in Orange County.  With a reputation of providing quality and dependable services, Colonial takes pride in being a company with old-fashioned values. Our team truly cares about the well-being of our clients.  And because we care like you do, you can consider us "Next To Family."

Colonial Home Care’s Professional Management Team will make sure everything flows smoothly for you and your family.  This includes: assessing your situation, scheduling according to your needs, ensuring the right Home Care Aide is provided, and making sure things go the way you want and expect.  Our Management Team has over 50 years of combined experience working with Colonial, and over 65 years of combined experience within the home care industry.

Trevor O'Neil President

Trevor has overseen Colonial's business operations since 1994.  With nearly two decades of experience in home care, Trevor is a respected and influential home care advocate in California and across the nation.  He maintains active leadership roles in local, state and national home care associations, and is considered by colleagues and competitors to be an expert in most everything "home care" related.  Additionally, Trevor has provided expert testimony and review in legal matters pertaining to home care.  Trevor is a Certified Care Manager (CMC), and holds a Bachelor's degree in Computer Science.  A Southern California native, Trevor resides in Anaheim Hills with his family and enjoys gardening, hiking, and most outdoor activities.

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.

Sandra Williams Client Services Manager & Community Relations

Sandra, our Client Services Manager and Community Relations Specialist, began her career with Colonial Home Care in 2004. In addition to working with clients and Home Care Aides with their ongoing care and scheduling needs, Sandra develops and maintains Colonial's relationships with area hospitals, nursing homes and community organizations.  Whether in the office or out in the field, Sandra is continually working to enhance the level of service for which Colonial has become known.  Sandra has two sons who keep her busy at home, and with her husband is active with her sons’ sports leagues.

Christine Kasprzak, LVN Field Supervisor


"Chrissy" serves as Colonial's Field Supervisor, helping to ensure that our clients are well-taken-care of and that our Home Care Aides are performing their duties according to clients' needs and company policy.  She regularly visits with our clients to ensure that their care plans are up to date, and she performs on-site staff evaluations.  Chrissy's passion is in helping others, and she considers being a nurse a long-held dream come true.  At home, Chrissy enjoys spending time with family, baking, and bike riding at the beach.
