Dr. Rosengren is an allergist and much, much more. I only made it through half of my allergy test with all the pricking and the poking and the glaven, but had I continued, I’m sure I would have found out what I was allergic to and my life would have improved way back in 1993 instead of waiting until 2005 to get on Nasacort. Don’t waster 12 years like I did; go see Hal today.
