What People Say About Dr. Patrick Win, MD
RecentMost Helpful
If I could give Dr. Win a 10, I would. I have struggled for 4 years to find someone who would take the time to really listen and offer constructive options that will enable me to get back a quality of life that I have not enjoyed for some time. You need look no further to find one of the best right here at home. I have been to the Mayo Clinic and I would say the caliber of medicine practiced by Dr. Win is every bit equal to that you would obtain at Mayo’s. We are lucky to have him.

Before seeing Dr. Win, I had been making pretty regular doctor visits' to my primary, she had been trying to get me to go an allergist for awhile due to that fact I was in in her office quite a bit for sinus, ear and throat infections. I kept praying that I would get better and wouldn't have to see a specialist but I kept getting worse, my symptoms were more frequent and co-pays were adding up, that was about 5 1/2 years ago. I was able to mow my lawn this year with no problem. Thanks to Dr. Win

We have used Dr. Patrick Win for our child with life-threatening food allergies and asthma since he opened his practice in Shiloh. After trying many STL area allergists, he is the one we trust most with our child's care.
