Karen Sleno has been spreading her love of calculus (and all math) with her students as well as teachers around the world since 1994. She received her B.S. in Mathematics Education degree from Saginaw Valley State University and her M.A. in Mathematics from Oakland University. With experience in both parochial and public high schools, she has taught at Flushing (MI) High School for the past 30 years, covering all math subjects from Algebra I through AP Calculus AB and BC. In addition, she serves as the department chair, a role she has fulfilled for the past 26 years. In her free time (!), she is also an adjunct instructor at Mott Community College and at the Center for Talented Youth at Johns Hopkins University. Her experience with AP Calculus AB and BC led her to be a participant at the AP reading for the past 18 years, first as a reader, later in the roles of table leader and then question leader, and most recently as an exam leader. Karen has served as a consultant (for 9 years) and as an AP Mentor for both AP Calculus and AP Precalculus and was part of the review team for the transition of Khan Academy to be a College Board-approved AP Calculus review site. More recently, she has been serving on the AP Calculus Development Committee as well as the Annual AP Conference Steering Committee. Additionally, she is currently working with the Calc Medic team to construct lessons for BC Calculus and activities for AP Precalculus. Her efforts in education and in the AP program earned her recognition as Educator of the Year for her district in 2015, as a Michigan Regional Teacher of the Year in 2022, and as a PAEMST state finalist in 2023.

Brian Shay earned his B.A. and M.A. in Mathematics from SUNY Potsdam and his M.A. T. and M.A. in Mathematics from UC Davis. He began teaching in 2000 and has been teaching AP Calculus AB and BC since 2003. He also teaches all levels of high school mathematics classes, as well as Calculus 3 and Linear Algebra. He has been teaching at Canyon Crest Academy in the San Dieguito Union High School District since 2004. 

Brian has been a reader for the AP Calculus exam since 2010, served as a Table Leader since 2018, and a Question Leader since 2021. In 2020 he became a member of the AP Calculus Test Development Committee. He presents at state, regional, and national conferences. He also has helped to write the Teacher’s Edition of an AP Calculus Textbook. He is an active member and leader of local, state, and national professional mathematics teachers associations. 

Brian has won numerous awards for his teaching and service, including the 2019 Presidential Award for Excellence in Math and Science Teaching, 2012 George Polya Memorial Award, 2020 Edyth May Sliffe Award, and 2009 Teacher of the Year for his school district. In 2008 he was also awarded a Fulbright-Hays Scholarship to study the schools and culture of India. He loves to travel, is an avid foodie, father of an adorable Great Dane, and husband. 

After 30+ years in education, Paul Gruber  still has a love for teaching and has a blast with his students.  His classroom is mixture of  constant work, lots of movement,  vertical learning and  kids always laughing. To that end, he enjoys doing APSI workshops in Calculus (and now PreCalculus) while meeting many wonderful people.  Though newly retired as of June 2023, when giving this workshop, for nearly his entire career, because of his belief in equity, he has taught in urban districts.   For twenty plus years he taught at Elizabeth HS in Elizabeth, NJ.    Several years ago, EHS had only a handful of students take AP Calculus, annually.   One year, no one signed up for the class - the principal was bothered by this and asked the top students what would it take for them to take AP Calc.  They said, "If Mr. G teaches it, we'll take it".  The first year, twelve students signed up.   Within ten years, the program has grown to 150+ students taking AP CalculusAB and BC .  Now his mission is to get as many people as possible to take AP PreCalculus.  Paul has also worked as a Math Supervisor and has taught in NYC for ten years. As for presentations he does not only present the Calculus/PreCalculus, but he believes in creating better teachers.     To that end, he inculcates much of what he knows on Brain-Based Learning and in the importance of changing a paradigm through the proper uses of transfer, discovery learning, primacy-recency theory,   vertical learning, cooperative learning, and closure,  In this workshop, he will share the C.E.D.,  a variety of kinesthetic activities, develop difficult concepts in “baby steps”,  will do specific AP questions while reviewing the grading process, and discussing equity .  Paul has been a teacher for 30+ years, grader of AP Calculus exams for ten years and an APSI facilitator for eight. He was a Question Leader on the 2024 AP PreCalculus Exam.   Paul  earned a BBA from Baruch College, an MA in Math Education from CCNY-NY and was a EdD Candidate at Columbia University / Teachers College in Math Education.  Paul is married for over 38 years, has three children , two grandchildren and a passion for baseball.   As a fun fact, between his freshman and sophomore year in college, in 1976, he traveled and worked with the elephants of  Ringling Brothers and Barnum and Bailey Circus.

Penny Smeltzer began teaching AP Statistics when the course began and quickly created one of the largest programs in the nation in Austin, Texas. Her recognition includes Presidential Award Finalist, O’Donnell AP Teacher of the Year, Intel Teacher of Merit, Texas Exes Outstanding Teacher, the national winner of the Siemen’s Teacher Award, and Toyota International Teacher Award. Her passion for AP Statistics continues with years of experience as an AP Statistics exam grader, grading leader, rubric writer, Test Development Committee member, and Question Leader. Her passion is creating meaningful interdisciplinary lessons with science using topics that matter in the lives of the human population and the planet. Penny presents lively, interactive workshops to teachers in AP Statistics and integrated sessions with Lessons That Matter. On a good day, Penny has her camera, a notepad, and a ridiculous amount of curiosity as she explores the world for new interesting lessons…most recently in Uganda trekking gorillas.
