Tessa H.

Tessa H. is a lifelong learner who became a teacher so she could grow personally and professionally. She loves meeting new people and sharing her interests with students while they solve problems together.

Tessa has taught everything from swim lessons for young children to college-level Geology labs to reading and math to elementary students with learning disabilities.

As an undergraduate at the University of Binghamton in New York, Tessa discovered her passion for science and the environment, which led to two bachelor’s degrees: one in Geology and one in Environmental Studies.

After graduating, her first “real job” was teaching reading and math to children with autism and other learning disabilities. Tessa enjoyed seeing her students grow so much that she stayed in that job for more than 7 years.

“Pairing with each student and learning how to integrate their interests into my lesson plans has helped me become a better teacher and made learning more fun for everyone.”

Tessa recently moved from New York to Colorado to pursue a career in science. Tutoring gives her the opportunity to continue her love of teaching and her passion for giving back to the community.

When she’s not teaching or tutoring, Tessa loves getting out into nature, going for a hike, or going on a picnic. I also love learning new skills — anything from knitting to breadmaking.

Chris R.

Chris R. is research scientist in the Biochemistry Department at the University of Colorado Boulder, where he studies gene regulation and teaches biochemistry.

As a teacher/tutor, Chris enjoys creating a dynamic learning environment and mentoring students through examples of chemistry and biochemistry in the real world.

Chris’s interest in science started in high school biology, where he became fascinated with the molecules that make up life and how they all work together (to the point of asking for a microscope for Christmas).

He went on to pursue this interest at Boston College where he earned a B.S. in Biochemistry. While in Boston, Chris did cancer research at Harvard Medical School and had his work published.

After graduating, Chris pursued his passion for teaching at Cristo Rey College Prep High School in Fort Worth, Texas — where he taught Chemistry and AP Chemistry. Concurrently, Chris received his M.Ed. from the University of Notre Dame in Secondary Science Education.

While teaching, Chris decided to take his passion for science to the next level by pursuing a Ph.D. in Biochemistry.

Outside of work and school, Chris likes to play golf, ski, fish, play guitar, and make the most of the outdoor recreation available in Boulder!

Dr. Michelina N-O.

Dr. Michelina Nelson-Olivieri developed a lifelong love of reading and writing as a child growing up in rural East Texas. Her favorite writers include Jeanette Winterson, Emily Austin, and Joy Harjo.

She received her B.A. and M.A. in English from Sam Houston State University, and her Ph.D. in English from the University of Denver. During her time at DU, she taught several English courses and tutored in after-school programs and at the University Writing Center.

Michelina’s passion is helping students of all ages find their written voices and learn to understand the world around them through other literary voices.

When she is not helping students learn to read and write with confidence and ease, you can find Michelina hiking with her family on trails all over the Front Range.

Travis McG.

Travis McGinnis has a bachelor’s degree in Elementary Education from Regis University, with endorsements in both Gifted and Talented Education and Social Studies. With 15 years of classroom experience in the Adams 12 and Jeffco School Districts, Travis is an expert at guiding students through Reading, Writing, and Math using goal-setting and arts-integrated methods.

In 2017, Travis was awarded the Talented Teacher Award by the Jeffco School District, and recognized for “100% student achievement,” as all his students met or exceeded their goals in Reading, Writing, and Math. In 2016, he also contributed to Devinney Elementary School winning the National Blue Ribbon Award.

Outside the classroom, Travis enjoys playing soccer, boardgames, baking sourdough bread, and writing fantasy and science fiction novels. When he’s not writing, gaming, or baking masterpieces in the kitchen, he enjoys quality time with his wife, four children, and their mini-goldendoodle puppy.

Travis’s experience as an educator, his enthusiasm for learning, and zest for life make him an ideal “smart friend” for elementary and middle-school students who could use a little inspiration to overcome challenges and master the learning process.

McCall D.

McCall D. is exceptional at helping students grasp concepts and gain confidence in Middle-School Math, Trigonometry, Pre-Calculus, and English Composition.

McCall enjoys helping students learn how to bridge the gap between big-picture mathematical concepts and solving specific problems using those concepts.

Her goal is to help students gain confidence, improve their understanding, and realize, “Hey, wait a minute. I’m actually good at math!”

As a graduating honor-roll senior at Silver Creek High School in Longmont, McCall will be attending Colorado State University in the fall, where she plans to major in Biomedical Engineering and Biochemistry.

In her spare time, McCall works with a local equine veterinarian and spends time with her friends, family, and her three dogs: Anzu, Zeke, and ZuZu.
