Q&A with Kristina Diaz ’03

Why did you choose the U of A? 

Honestly, it felt like U of A chose me. The Honors College reached out during my senior year of high school, and I attended a summer session that made me feel instantly at home. The campus was welcoming, with endless opportunities for someone still exploring their path. Looking back, everything aligned perfectly. 

What is your favorite memory from attending the U of A? 

It’s hard to choose, but some of my favorite memories are cheering at Arizona football, basketball, and softball games. The energy, the crowd, and the school spirit were unforgettable. Those moments created a deep sense of community and pride. I can only hope my children experience that same excitement and connection at their future universities.

What was your favorite spot on campus?

I loved studying in the peaceful downstairs area of Old Main because I was able to enjoy Tucson’s beautiful weather while staying focused. For fun, nothing beat grabbing a bite at Frog & Firkin or Bison Witches with friends. Those spots, along with the entire campus, made everyday moments feel special. 

What are three words you would use to describe the U of A? 

Supportive, excellence and vibrant. U of A fostered a community where I felt encouraged to grow, challenged to excel, and was surrounded by energy and opportunity. Those three words truly capture the spirit of my experience. 

What extracurricular activities did you participate in? 

I was part of the Honors Society in my first two years and played Ice Hockey during my junior and senior years. Balancing academics and athletics was challenging but incredibly rewarding. Those experiences shaped my discipline and gave me lifelong friendships — some of my most meaningful college memories came from both the classroom and the rink. 

What was your favorite class? 

Surprisingly, my favorite class was Egyptian Papyrus. Though unrelated to my career, it fulfilled a humanities requirement and left a lasting impression. Analyzing a single letter to uncover cultural and historical insights was eye-opening. It deepened my appreciation for archaeology and sparked a lifelong fascination with ancient Egyptian civilization. 

What’s one lesson you learned during college that you still apply today? 

One lasting lesson from college was the discipline of academic writing. That foundation supports my work today, whether I’m submitting national presentations, leading quality improvement initiatives or publishing in academic journals. I’ve held national academic leadership roles, and looking back, it all began with the writing rigor I developed at U of A.

What’s one piece of advice you’d give an incoming freshman? 

Be proactive and stay organized. At the start of each class, add all due dates to a calendar and break tasks into manageable steps. Studying a little each day beats last-minute cramming. And don’t underestimate office hours — they’re a great way to connect with professors and stay on track. 

In addition to staying on top of your coursework, take time to explore. Try lots of things — even those outside your comfort zone. College is a unique opportunity to explore interests you may not get to pursue later. That could mean taking a class that isn’t directly tied to your career goals, joining new activities, meeting people with different interests or uncovering hidden talents. And be sure to find a mentor, someone who can offer guidance, encouragement, and perspective along the way. 

How has your degree helped in your career? 

My Business Administration degree laid a strong foundation that became invaluable later in my career. After medical school and residency, I began as a family physician — but as I stepped into leadership roles, my business background proved essential. I never imagined how seamlessly those two paths would align, but together, they’ve shaped a well-rounded and fulfilling career. 

What’s one thing you wish more people knew about your career? 

Though I started business, medicine became my calling. One opportunity led to another: teaching residents, becoming a program director, Chief Academic Officer, Designated Institutional Official and President of the Medical Group. I’ve learned that saying yes, even when it’s scary, can open doors you never imagined. Sometimes, the most unexpected paths lead exactly where you’re meant to be.
