Guthrie educator Sharrell Sincere

A future in healthcare can take many forms. 🩺 SBISD Health Science teacher Sharrell Sincere helps students discover careers they may never have considered and see how their strengths could make a difference in someone’s life.


Students often ask when they will use what they learn in class. For Health Science teacher Sharrell Sincere, the answer comes from experience.

With 18 years in medical imaging and more than a decade teaching in higher education, she connects classroom lessons to the care patients receive every day. Now in her fourth year in Spring Branch ISD (SBISD), she helps students explore healthcare careers and understand the steps they can take to pursue them.

“Teaching Health Science as part of SBISD's Career and Technical Education (CTE) program at Memorial High School (MHS) allows me to introduce students to healthcare careers while helping them build a foundation for their futures,” Ms. Sincere said.

Her career began as a registered radiologic technologist specializing in radiography and computed tomography, or CT. Along the way, she discovered that educating others was one of the most rewarding parts of her work. Whether explaining a procedure to a patient, mentoring a student or training a future healthcare professional, she enjoyed helping people understand something new.

Looking under the microscope

Teaching high school offered an opportunity to share that experience with students as they begin considering their futures.

In her classroom, students study medical terminology, anatomy, disease processes and healthcare practices. Case studies, hands-on activities and laboratory experiences help them apply that knowledge to situations healthcare professionals encounter.

“Through case studies, hands-on activities, laboratory experiences, and discussions about real clinical situations, I encourage students to think critically, communicate effectively, and develop professional skills,” she said.

Students also learn how broad the healthcare field is. Beyond medicine and nursing, they explore medical imaging, laboratory science, respiratory therapy, rehabilitation and healthcare administration. Guest speakers and participation in HOSA offer opportunities to learn from professionals, develop leadership skills and understand workplace expectations.

For Ms. Sincere, some of the most rewarding moments happen when a student becomes excited about a specialty they had never considered.

“Sometimes, introducing a student to a career they never knew existed is the first step toward helping them find their purpose,” she said.

That discovery supports SBISD’s T-2-4 vision.

Sincere's goal is to help students make informed decisions before committing to a college major or career path. She encourages students to recognize their strengths and understand the different routes into healthcare, including technical certifications, associate degrees, bachelor’s degrees and advanced professional education

As SBISD celebrates its 80th anniversary, Ms. Sincere is proud to help prepare the next generation of professionals who could one day care for their communities.

“Knowing my students might one day become the nurses, physicians, radiologic technologists, therapists, and other healthcare professionals serving our communities makes my work meaningful,” she said.

Asked what is possible in SBISD, her answer reflects that hope: “Inspiring today’s students to become tomorrow’s healthcare professionals.”


SBISD will celebrate T-2-4 Week Nov. 16–20, highlighting opportunities beyond high school through technical training, two-year and four-year colleges, military service and careers.

Educators like Ms. Sincere bring that vision to life by helping students connect their interests to opportunities and prepare for what comes next.
