Recommendations for concierge health/preventative health specialists?

I’m pretty into my health and really would like to up my monitoring/take protective measures to live long and healthy.

This said, healthcare in general — and certainly in the good ole US of A — is more about maintenance and less about prevention.

I was wondering who you might recommend given my goal of prevention? I.e. happy to pay for a CAC scan out of pocket, but you might need a referral… most docs wouldn’t. Others would recommend even if I didn’t ask them to (this is the type of doc I’d like to see)
