I would shop around for a doctor in network. Just because your friend had a "good" experience does not mean that you will have one. Tricare is no fun when you go out of network and they do like to drag their feet even on in network.
Things may have changed since I had medical issues with son but they are no fun.
Congratulations and good luck to you.

PS Don't look trouble in the mouth by going outside their system.
