The Allergy and Immunology Fellowship draws fellows from across the U.S. and around the world. While all of our fellows have a love of learning and a compassionate approach to patient care, they come from diverse backgrounds, family status, and professional and personal interests. Meet our current fellows and learn about their experience in the program.

Residency: Internal Medicine, Mayo Clinic 

What attracted you to allergy/immunology?

I was attracted to allergy, asthma, and immunology because of the variety of patient diagnoses, the option to see a balance of children and adults, my fascination with the human immune system, and the ability to strongly impact a patient’s quality of life.

What makes this program unique?

Our program does a remarkable job of helping each individual fellow achieve their own goals and aspirations. All of the staff are kind, supportive, and available to help. There are plenty of opportunities to sharpen clinical acumen, while also delving into research and education.

Why did you choose Mayo Clinic?

The opportunity to learn from the best. Mayo Clinic and Phoenix Children’s Hospital are the premier teaching institutions in Phoenix so to get the opportunity to learn and grow at these institutions is a blessing.

What do you like about living in Phoenix?

A lot of different things to do in the city. When on tour, most musical acts do a show or two in Phoenix, such as Beyonce, Lizzo, and Usher. Every professional sports team is located in the city so you get a chance to watch the best in their respective sports compete (Go Dodgers!), ASU Gammage theater performs Broadway shows, including The Lion King, Hamilton, and MJ the Musical. There are a lot of great eateries and different cultural foods. I can easily get to Las Vegas, LA, San Diego, or my hometown in southern California, Rancho Cucamonga which is located in the IE (Inland Empire). There is an international airport, so you can get to a lot of different cities on direct flights including Toronto. There's also great weather nine months out of the year!
