@parkin41 Seeing that you mentioned living in Oakland, that is Alameda County. Here is the website for their senior services. https://www.alamedacountysocialservices.org/our-services/Seniors-and-Disabled/Area-Agency-on-Aging/Area-agency-on-aging

I have found very valuable and timely information when using the AAA sources! An ombudsman is going to be able to help you find a good insurance broker, and offer ideas for getting your dad and mom settled in. As others have mentioned, check with your friends and acquaintances, they might give you names from their parents, also! A cross-country move can be quite intimidating for all involved, and I applaud you in taking this on.
