What is the most rewarding thing about serving the eye care industry?

My career in ophthalmology started when I was hired as a technician in a single-physician general ophthalmology practice after college. Patients would come in with many different problems, but they all had one thing in common; they were afraid they’d lose their eyesight. Eyesight is the one sense that people generally fear losing the most, and this doctor helped alleviate that fear and gave them hope. I learned so much from him. Years later when I worked for a small corneal device company, we developed an artificial cornea that was implanted in patients that were legally blind but had some visual potential. We treated an older patient who had been blinded due to bilateral chemical burns when young. This patient had never seen the faces of their spouse or children. After surgery, for the first time in this patient’s life, they were able to see the faces of family members, the home they lived in, and the garden where they would sit and listen to the birds. These are things many people take for granted. This patient said they never gave up hope that someday they would be able to see again.

For me, the most rewarding thing about working in eye care, especially research, is the ability to give hope and help preserve/improve vision.

Hobby: I love traveling to faraway lands (or not-so-distant places) to feed my wanderlust and to learn about new/different cultures. My next big pleasure trip will be to Costa Rica for a holistic retreat and scuba diving. When my schedule doesn’t allow for travel, I spend time outside and gardening, trying to prevent my dog from killing the plants, listening to live music at small venues, and exploring open spaces close to home. When the weather warms up, I look forward to giving overlanding a try.

Birth Month: September (Virgo)

Favorite Movie: I Origins is the first film that comes to mind; its science, suspense, and supernatural all rolled into one. The “windows to the soul” play a key part of this film.

Favorite Food: Oh, there’s so many… this Midwest girl likes to eat and try new things. Out of respect for the state I currently live in (Idaho), I’ll say my favorite food is potatoes. They are super versatile and served breakfast, lunch, dinner, and happy hour. What more could you want?!?

Favorite Precision Vision manufactured product?: ETDRS (Early Treatment Diabetic Retinopathy Study) charts and illuminator cabinets! These cabinets and charts have been an integral part of my life for the past 2 decades.

My first experience with ETDRS equipment was when I was certified as a BCVA visual acuity examiner and researcher at Southeast Clinical Research in Charlotte, NC. The cabinets and charts became an even bigger part of my life when I worked as a BCVA trainer and certifier for Emmes OPTYM for nearly a decade. These charts and cabinets have been a constant reminder of quality regardless of where I was in the world.

What is your favorite Precision Vision core value?:
“Driven to make a difference” aligns with my personal mission in life: to leave the world a better place than when I was brought into it.
