I know this is a weird recommendation but if anyone ever needs to see an allergist, Dr. Rogers in Fort Worth is absolutely amazing.
He has worked with us, via phone, for about a year now about Mason's egg issue. It is not an allergy and the only specialist for this intolerance is up north (New York, I think).
He blows us away with his kindness and his willingness to help. All of this, again, is outside of his specialty and outside of his office. We are not paying him for the guidance he gives us.
My family is so blessed by this great man. So i recommend anyone, if they ever need his specialization, contact him. He will treat you like a human and he truly cares for his patients.
