Fresh out of high school and looking toward southern Arizona to begin a new chapter of life, Scottsdale resident Stefan Koester aims to make a difference in the lives of others.

The young student might only be 18-years-old, but he radiates with ambition, fueled by the passion to help. Growing up, Mr. Koester’s father advised him to find a career doing something he loved — for Stefan, that will be a career in the medical field.

With a published medical paper and a lifesaving technology application under his belt, Mr. Koester has already begun his journey. Among being awarded the Charros All-City scholarship, and placing in the Arizona state tennis championships, Mr. Koester also was named valedictorian at Chaparral High School, graduating with a 4.93 weighted GPA.

“My goal really is to combine my love for people and my passion for medicine,” said Mr. Koester in a May 30 phone interview.

He is now headed to University of Arizona in Tucson to study pre-med and physiology.

Beginning at a young age the medical field sparked Mr. Koester’s interest — especially after dissecting a frog in middle school.

“I was always interested, since 6th grade, in studying the heart,” said Mr. Koester.

However, as he’s gotten older his interest in the medical field has grown.

“I’m not restricting myself only to cardiology because I love so many fields of medicine, it’s just where my passion lies now,” said Mr. Koester. “Helping people through my passion of medicine is really my ultimate goal.”

At the age of 16, Mr. Koester formed a club on campus called Random Acts of Kindness, to help build a community of helping others at school.

“People could help each other to perform just little small random acts in everyday life,” said Mr. Koester. “Through there we’ve been able to go to shelters and provide food for the homeless.”

Mr. Koester hopes his younger sister Grace will carry on the club at Chaparral.

Recently, the incoming college-freshman designed a smartwatch application that guides users through the steps of CPR. His hopes for the wearable tech piece are that learning CPR becomes more popular on a consumer level, stating a oftentimes users have to pay for a class in order to learn CPR.

The watchfaces are on the app store, with four options available.

“The main goal of getting more people to use them is of course the marketing of these watchfaces. So getting on Reddit and blog platforms, and getting them tailored to certain professions is where I’m at now,” said Mr. Koester.

Although some of the projects he takes on are time consuming, it isn’t about the time, says Mr. Koester.

“I really just love helping people, and I always have,” he said. “It’s just something in your nature.”

In his free time, the teen also enjoys DJing and playing tennis for up to two hours a day. Enjoying life and doing what you love has been instilled in Mr. Koester’s life. His father has taught him the value of enjoying your career.

“He tells me that you have to follow what you love everyday, and spend every day of your life doing it,” said Mr. Koester. “He’s taught me a lot of about faith and a lot about being a true business man and a real person.”
