My employer uses HSA bank which links with TD Ameritrade for the investment side. They are decent otherwise I’d also be at fidelity.
We have a zero fee HSA through Lively, serviced by TD Ameritrade. Apparently they're going through an acquisition by Charles Schwab and are introducing a $24 annual overhead fee. I also haven't been able to see what funds will be available after transition, and what their fees might be.We'll be switching to fidelity if Schwab doesn't have any low fee fund options
