I was born and raised in New Orleans and have lived in Indiana since 1998. I spent six years working as a pediatrician in suburban Chicago, and during this time I developed an interest in allergy and immunology and decided to pursue training in the field.

After spending two years working in South Bend, I moved to Indianapolis in 2000 and joined a multi-physician allergy group. In 2006, I opened my own practice on the south side of Indianapolis. In 2015 we relocated to our current location in Greenwood.

I enjoy the specialty of Allergy and Immunology not only because of the intellectual challenges but also because of the opportunity to help people who have allergic and immunologic disorders. It is a blessing to take care of people of all ages and help them to live full, active lives, and we are grateful that so many of our patients refer their family members and friends to our practice.

In my spare time, I enjoy cooking, especially my Louisiana favorites such as gumbo, red beans and rice, jambalaya, and beignets. I exercise regularly so I can continue enjoying my comfort foods. I also enjoy spending time with family and outdoors, watching all of the wildlife in our backyard.
