Allergist recommendation (MCAS)

Hi hello,
I’m wondering if anyone has recommendations for allergists in the Omaha area who are proficient with diagnosing and treating MCAS and/or other mast cell disorders.

My neurologist wants me to be evaluated for MCAS after a particularly bad reaction to a procedure that doesn’t normally have systemic side effects (and worsening symptoms generally over the last few years).

But with mast cell disorders (and MCAS specifically) being so new and somewhat controversial, I’d like to find a recommendation for a doctor who has familiarity with mast cell disorders.

TIA to anyone who might have some good info :)
