About Us

Our primary mission at Interim Healthcare is to Improve People's Lives, while keeping them out of the Hospital. That is what we do every day.

Patrick Chamberlain - Owner/Administrator

Patrick and his wife Pam have lived in Orange County for over 30 years.  He began a 25 year career supporting the Cardiovascular Medicine community in 1992 at Applied Cardiac Systems, which at the time was located in Laguna Hills, about half a mile from the Interim Healthcare office. He frequented Polly’s Pies and other local businesses and became fond of Laguna Hills and the seniors that call the area home. Pam, an accountant, earned her CPA License, and became a Partner at a local accounting firm. Patrick and Pam were married in 1988, and raised two children. Both are graduates of El Toro High School in Lake Forest and both have since gone on to obtain Bacholors Degrees at National Universities.

As empty nesters the Chamberlain’s began to search for a way to give back to the community that had contributed to such a rich environment for raising a family.  They found a way to do just that in partnering with Interim HealthCare and a fabulous group of local Caregivers. 

Vivian Villalobos - Director of Care Services

At age 13 Vivian began a lifetime of service to the elderly working as a candy striper in the ICU and Labor / delivery units at Harbor UCLA Medical Center in Torrance, CA. At age 15, after moving to Long Beach, she volunteered at a local lockdown Alzheimer’s / Dementia unit. In high school she finished the ROP and clinical training to become a Certified Nursing Assistant (CNA). Since she was not legally permitted to work as a CNA until the age of 18 Vivian volunteered at a Skilled Nursing facility and completed the hours needed for her CNA as a minor. 

In 1995 Vivian began her professional career as a Caregiver with Interim Healthcare in Long Beach, CA. She was quick to accept the tougher cases where her skill set and experience allowed her to shine. Within 6 months, and still 18 years old, she promoted to a supervisory role (still 18 years old).

 22 years later Interim Healthcare of Orange County was delighted when Vivian accepted the position of “Director of Care Services”.
A quote from Patrick Chamberlain: “Our clients, and the residents of Orange County, will be hard pressed to find anyone that has more experience providing in-home care than Vivian. She consistently goes above and beyond to ensure all of our clients receive the care they need, exactly when they need it.”

When it matters most, count on us. Interim Healthcare.

I want to express my appreciation and gratitude for your help with my Mom. She has grown very close to a couple of your care givers. Everyone is prompt and considerate of her needs. It’s comforting to know I have people who I can count on.
