It's virtually impossible to list the best doctors for concussions. Every concussion presents differently. Plus, there is no one treatment for concussion. You treat each symptoms individually. If there are vestibular problems, a vestibular specialist would be good.

There are plenty of concussion clinics. They are set up to treat sports concussions. Most are more about comprehensive insurance company billings that true specialists. Most are followers of the ImPACT or other Computerized Neurocognitive Testing systems.

What are your worst or most problematic symptoms right now ? What have you been doing to help with recovery ?

What advise have you been getting for your doctors and others ?

A multi-vitamin and 1000 mcgs of B-12 is far less than what a recovering brain needs. A single multi is usually only good at preventing malnutrition, not supporting best health.
