David Gomprecht, PhD, graduated from Wesleyan University, where he majored in mathematics and physics, and then went on to receive a Ph.D. in mathematics from the University of California at Berkeley. After working as a research mathematician for a few years, David returned to his hometown of New York City, where he has now been a math specialist and private tutor for over twenty years. His work with students has spanned a wide range of ages from third grade through college.

In recent years, David has become increasingly interested in enrichment mathematics, at a variety of levels. At the competitive independent school where he works, he enjoys running the fifth and sixth grade math club and coaching the high school math team. David is also a long time instructor at the New York Math Circle, where he teaches the most advanced middle school class and the most advanced high school class. In addition, David very much enjoys creating math problems, and is proud to have had problems on the American Invitational Mathematics Exam (AIME) in both 2017 and 2018. In 2017 David also spoke at the Berkeley Math Circle about geometry, one of his favorite topics.

In addition to enrichment work, David has honed his craft over the last twenty plus years by teaching a broad variety of mathematics classes, including algebra, geometry, precalculus, calculus, multivariable calculus, and linear algebra. He has taught precalculus and geometry each year for the last twenty years, and is currently putting the finishing touches on a precalculus textbook that he has written. David also has been a student advisor and a grade dean, and he has been a member of curriculum committees at his school and at the Hunter College Elementary School. Additionally, with the support of the school where he teaches David has fostered relationships with math departments in India, China, and Turkey, and he has taught math classes in Delhi and Beijing.

When David isn’t teaching, he spends his time cooking dinner for his wife and three children, helping his kids with their homework, and pursuing his interests, which include reading, running, cooking, and playing the sitar.

Ilanit Helfand

Ilanit Helfand has always loved math. She graduated summa cum laude from Barnard College with a degree in math, and then she went on to complete her Ph.D. in Mathematics from Northeastern University.

In graduate school, Ilanit started teaching math and realized that she loved teaching as much as she loved to study math. She taught courses to undergraduate students and started to privately tutor students as well both for course work and test preparation. In 2011, she moved from Boston to Tel Aviv, Israel, and began to teach online courses. After moving back to the United States, she continued to teach online. She currently serves on the online teaching faculty at a number of universities including Northeastern University, Southern New Hampshire University, Embry-Riddle Aeronautical University and the University of New Haven. She has also been involved in course design at these schools, creating written and recorded material which has been used by over 10,000 students.

At Northeastern University, Ilanit was nominated for the Excellence in Teaching award. At Southern New Hampshire University, Ilanit was nominated for an award for Commitment to Student Success, and she is the winner of the 2017 Award for Outstanding Instruction in STEM.

Over her years teaching math, Ilanit has focused on improving students’ relationships with mathematics. Many students come in with a fear of math or believing that they are not “math people.” Ilanit’s goal is to give students confidence in their ability to do math by exercising a growth mindset so that the benefits of the tutoring long outlast the time spent with the tutor.

Charlie Pfaff

Charlie Pfaff is a private tutor specializing in mathematics, physics, chemistry, biology, and test preparation, including the ACT, SAT, SAT subject tests, and AP exams. From a young age, Charlie always enjoyed helping his peers succeed. Years of assisting his classmates with their studies culminated in his service both as a tutor as well as a steering committee member for his high school’s extensive student-to-student tutoring service in his native Winnetka, Illinois.

Charlie received his Bachelor of Arts in Economics from Brown University in Providence, Rhode Island. This field of study afforded him the opportunity to explore his affinity for math and penchant for problem-solving as well as his love for communicating ideas. He spent time in courses that valued both numbers-based thinking as well as clear and concise written essays. As a result, he has vast experience to draw on when helping students in both quantitative and qualitative subjects.

At Brown, Charlie also served as a senior staff member for the school’s satirical newspaper, The Noser. As a senior staff member, he worked one-on-one with writers to improve the planning and execution of their articles. He’s well-versed in the tools and tactics to help writers hone and expand their ideas and vocabulary, catch errors, and eliminate needless verbiage.

Most recently, Charlie worked as a strategist and analyst for award-winning international advertising agency DigitasLBi, followed by a rapidly-growing Brooklyn-based startup called RUNA. In these positions, he used mathematical principles to improve the efficiency of marketing and sales. These roles regularly included breaking down mathematical concepts for easy understanding by his coworkers, in much the same way that he had done as a tutor in high school.

In each role, Charlie continued to teach himself new concepts, both out of necessity as well as a lifelong love of learning. In fact, his fascination with his own learning process led to him taking an online course from UC San Diego entitled Learning How to Learn. This course helped him solidify the intuitions about learning and instruction that he had gained as a tutor and an analyst. He has also spent time in the classroom, participating in an outreach program to teach community principles and business concepts to young students in Manhattan.

When not tutoring, Charlie enjoys watching Jeopardy!, playing guitar, and exploring Brooklyn.

Angela Krontiris Lowery

December 25, 2016

As a young child, Angela Krontiris Lowery found herself creating and solving self-assigned numerical and geometrical puzzles. From summer evenings spent predicting the schedules of the railroad trains near her house, to winter weekends spent sequencing similar sidewalk contours on her pocket map of Brooklyn, Angela’s detective-like curiosity led her to indulge in an education filled with mathematical lucidity and certainty.
Angela graduated with honors from Fordham University with a BA in mathematics and business. While attending Fordham, Angela successfully tutored many students in the HEOP (Higher Education Opportunity Program); because of her highly regarded teaching style, she now serves as a professor for HEOP at Fordham University. Angela is also an instructor at the Mathnasium Learning Center in Park Slope where she brings her engaging and interactive lessons to the table. She is known to build her tutoring sessions around meaningful examples relevant to her students’ passions, hobbies, and intrigues.

Pre-Algebra, Algebra 1 & 2, Geometry, Trigonometry, Pre-Calculus, College Algebra, Statistics, and Calculus are all subjects Angela is ready to tackle with her students. In addition to elementary and middle school math topics, concepts and skills, Angela also tutors for the math and science sections of standardized tests, including ISEE and ACT.

Aside from her love for mathematics, she plays softball in a women’s league in Brooklyn. She enjoys the fall and going to New Paltz and the Fingerlakes to see the fall foliage.
