About Us


Scott Moerschbacher is the owner and founder of Left Brains Educational Consulting, LLC. Since 2012, he has worked with students in physics and math in the greater Washington DC metro area. He earned a PhD in physics from The George Washington University and worked as a university professor for eight years before transitioning to the field of private tutoring.  His passion for education led him to start Left Brains.  Scott takes a philosophical approach to education.  His philosophy grew out of his search for an answer to one of the most common questions a teacher of physics and math receives from students:  "When will I ever have to use this?"  In truth, it's really not about the physics and math at all. 

Rather, the reason for taking these classes is to cultivate the skills associated with proficiency in math and physics. Such skills include critical thinking, prioritization, problem solving, organizational skills, discipline to embrace difficult problems, then see them through to completion, and so on. Once acquired, they then can be applied to other disciplines, and indeed to life.  This is representative of Scott's holistic approach to education.

Caitlin Hollowell was born and raised in Derwood, MD. Her philosophy has evolved and matured with every new experience. She believes in creating an environment that is safe for students to make mistakes, one that fosters kindness, and a space where we can discover how to learn to our fullest potential. Her philosophy celebrates helping one another in our educational journey instead of creating a competitive atmosphere full of angst and stress.


As a teacher, Caitlin invites her students to act with compassion by demonstrating it herself. She continually reminds her students that we are a class that takes care of one another, inside and outside the classroom. She strives to be a mentor to her students so that they feel they have a safe haven when they are in our classroom. In addition, Caitlin encourages students to open their hearts and minds to other mentors such as authors like, Ralph Fletcher, who relay positive and meaningful messages. She teachers her students that as humans, we have a responsibility to act respectfully towards one another concerning each other’s race, economic status, ideological differences, religion, and sexual orientation. In her own words, "As an educator, it is my job to act legally and ethically, demonstrating the importance of being a citizen who takes her role seriously as a teacher and societal member."



Mathilde Lambert is a senior at Walt Whitman High School in Bethesda, MD.  She is a native French speaker who tutors students in all levels of French.  Her students describe her as "funny" and "so nice," which contribute to her success as tutor.  Mathilde enjoys math and science classes and is thinking about majoring in Economics in college.  She has been tutoring French at Left Brains since Summer 2020.
Erin Smith fell in love with teaching as a college chemistry tutor. She earned a PhD from Purdue University in inorganic chemistry where she taught and tutored undergraduate and graduate students. Since 2012, Erin has taught high school chemistry and AP chemistry where she strives to challenge her students with creative approaches to fostering scientific curiosity.  Erin is loved by all of her students and has received many glowing recommendations from families whose lives she has touched with her tutoring and academic guidance.



Amy Siegel has worked as a high school tutor and Learning Specialist for the past eight years. Before that, she worked for twelve years as a college, high school, and middle school English teacher and for eight years as a school librarian. She loves working one-on-one with students because of the enormous satisfactions that derive from building a relationship based on a deep understanding of the student's strengths and challenges. Favorite quotation: "If a man does not keep pace with his companion, perhaps it is because he hears a different drummer."
Eric Cotton got his PhD in chemistry from Purdue University studying density functional theory and stochastic simulations modeling molecular compounds.  While pursuing his PhD, Eric founded ECI Wind and Solar, a successful energy company in Indiana.  Since 2013, Eric has been a professor of chemistry at The Community College of Baltimore County, teaching students of all ages and backgrounds. During his time at CCBC, Eric has won several awards for teaching excellence.  In his free time, Eric enjoys playing video games and camping. 








John Tyburski grew up in Northeast Kansas working on farms since the age of 11. He graduated from a small rural high school and earned his BS and PhD degrees in biological sciences from the University of Kansas. An award-winning instructor, John taught extensively on the undergraduate and graduate level during his PhD program. While a Cancer Prevention Fellow with the National Cancer Institute, John earned his Master of Public Health degree from Johns Hopkins University. As a Fellow, John completed four years of mentored research in the NCI's Laboratory of Metabolism where he applied mass spectrometry-based metabolomics to radiation biomarker development. He then joined the faculty of the Department of Biochemistry and Cellular & Molecular Biology at the Georgetown University. During these years, John was recognized multiple times for the quality of his research. His seminal publications in radiation metabolomics research have been cited over 400 times in the peer-reviewed literature.

John's philosophy is based on creating and maintaining a healthy lifestyle of learning. "How we spend our time determines what we are good at. If we spend our time on entertainment, then we will be great at being entertained. But if we spend our time solving problems, then we will become extraordinary problem-solvers." John takes a holistic approach to tutoring by addressing habits and lifestyle as well as academic performance. John always begins a tutoring relationship by learning about his students' habits and lifestyles and offering recommendations for changes. Establishing an optimal lifestyle of learning is foundational to achieving academic excellence.


In his "copious" free time, John enjoys being with his two children (above all else), studying theology and philosophy, volunteering to help the poor, and riding his bicycles and motorcycles. His ultimate mission is to leave a strong legacy of contribution for not only his own kids but all children and adults engaged in the pursuit of knowledge.
