Is it best to roll over funds to a new account when starting a new job? I worry about whether the new job will have fully vested contributions and whether that will affect my funds.

You should talk to a rollover specialist. Generally it's a good idea to rollover, but you want to check first.

I wasn't aware there were such people as rollover specialists. Would that be within the companies who currently have the funds and/or the company to which I would be rolling over the funds or an independent agent?

I would look to your new company first, the old company second and then go ind if neither of them have one.

Thanks for the advice. I checked with the new company and they have a specialist with whom I am going to meet. What a relief!

So how did it go? It's be nice if you posted the ins and outs. It might help someone else in the future. I have a broker who handles these matters so I do't have the inside scoop.
