“Wendy is the type of pharmacist every team hopes to have — meticulous, dependable and deeply dedicated to protecting our patients,” said Amy Warner, RPh, manager, Pharmacy. “Her knowledge and leadership support the team and our goals to keep patient medication safety in focus.”
We sat down with Wendy to learn more about her path into healthcare, what inspires her at work and what she enjoys outside the hospital.
What did you want to be as a kid, and how did you ultimately choose your career?
As a kid, I was fascinated by science and always curious about how things worked, especially the human body. I initially thought I’d become a physician, but over time I realized I was drawn to the precision and problem-solving side of pharmacy. I chose healthcare because I wanted to make a meaningful impact on people’s lives, and pharmacy offered the perfect blend of clinical knowledge, patient care and collaboration.
What is your workday like?
My role as a clinical pharmacist involves ensuring safe and effective medication use across the hospital. A typical day includes reviewing orders, verifying dosages, consulting with physicians and nurses, managing inventory and responding to urgent medication needs.
As the designated pharmacy superuser, I also play a key role in medication safety initiatives and help troubleshoot complex clinical scenarios. No two days are the same, which keeps things engaging.
One memorable experience early in my time here involved a patient who brought in a home medication bottle labeled as methyltestosterone and esterified estrogen. After examining the tablets, I discovered the bottle had actually been incorrectly filled by her local pharmacy with methotrexate, a drug that could have caused serious harm if taken in error. Thankfully, we caught the mistake before that happened. It was a powerful reminder of the importance of vigilance in protecting patient safety..
What is your favorite part of your job, and what is the biggest challenge?
My favorite part is being a trusted resource for the care team, especially when I can help prevent a medication error or offer a solution that improves patient outcomes. Being one of the smaller Texas Health facilities, the sense of teamwork here runs deep. My co-workers feel more like family, and that close-knit environment makes even the toughest days purposeful.
The biggest challenge is balancing the fast pace while staying meticulous and calm under pressure, but that’s also what makes the work so rewarding.
What’s something people would be surprised to know about you?
I’m a travel enthusiast and always looking for my next adventure. This year, I finally checked Greece off my travel bucket list. It absolutely lived up to the hype.
I caught the travel bug early, moving from China to America when I was just 4 years old. Since then, I’ve lived on nearly every edge of North America — Connecticut, California, Canada and now Texas. That constant change planted the seed for my love of exploring.
At home, things are lively with three young kids and two dogs. Fun fact: My husband, brother and sister-in-law are all pharmacists, too. My family is basically a walking pharmacy!
How do you do your life’s best work at Texas Health?
Here at Texas Health, my life’s best work starts and ends with one priority: patient safety. Every decision I make — whether it’s identifying a potential drug interaction, managing medication shortages or reviewing a complex regimen — is driven by the responsibility I feel to protect those in our care. I take that role seriously, knowing that even the smallest action can have a big impact on someone’s health.
