Never knew how much difference allergy shots can help when you suffer from seasonal allergies as bad as I do. Found Colorado Allergy and Asthma Center, and through their guidance, I am 1000% better than I've ever been. Entire staff is professional, caring, and concerned about your health. Wish I'd discovered them years ago. 7/100/2026 - De Tsai is the best ever, every time I have an issue with my allergies or asthma, she fixes it. She is the most caring, capable, and knowledgeable doctor in my large list of various doctors. 10/16/2026 - another follow up with Dr Tsai to go over how well the treatments she has recommended are doing. I slept with the windows open for the first time in years; that’s how it’s going.
