“My brother had severe asthma as a child and young adult, and that inspired me to choose medicine because it was a field in which I could apply my interest in science in a way that could directly help people. I always enjoy caring for asthma and allergy patients because we make people feel better and improve their quality of life. I believe it is important to get to the root of the patient’s problem and to not only treat symptoms. To deliver quality, personalized healthcare, I’ve become a better, more careful listener. In training, there is a precise ‘right way’ to approach every patient. In my practice, I’ve embraced the philosophy that care must be individualized.”

“Allergies are so prevalent and impact many people on a regular basis. As someone with allergic rhinitis, myself, I know how severely it can affect a person’s day to day living. I am lucky to have found a specialty where there is a lot we can offer patients and improve their quality of life. I enjoy treating patients of all ages and am interested in all aspects of allergy and immunology, including eczema, hives, asthma, food allergy and immunodeficiency.”

I wanted to feel better, but I didn’t want to give up my pets. A few weeks after Day 1 allergy relief, I can breathe again.

As a busy mother with young children, I didn’t have time for traditional allergy shots. But when I found out I could get better after just one half-day allergy therapy, I was sold. My stuffiness has gone away, and my eyes aren’t puffy. I recommend this to all my friends.

Allison K.

I had a miserable spring last year, but this year, after Day 1 allergy relief therapy, I was able to go outside again to bicycle and run. This is great!

John V.

I suffered from allergies for years, but I always thought allergy shots took too long to work. But now, one week after Day 1 allergy relief, I feel great. I should have done this years ago.
