Bio

I've taught math for more than 25 years at the middle school, high school, and college levels, including almost every math course from 7th grade math through Calculus, Statistics, and Linear Algebra. My career has been focused in teaching, and I really love leading students to uncover the power they have to understand complex ideas that they too often think are beyond them.

I've taught math for more than 25 years at the middle school, high school, and college levels, including almost every math course from 7th grade math through Calculus, Statistics, and Linear Algebra. My career has been focused in teaching, and I really love leading students to uncover the power they have to understand complex ideas that they too often think are beyond them.

In order to have that outcome I focus on learning where the student IS, mathematically. I teach students based on the background they actually have, rather than some ideal of "you should already know this". Connecting to what they know and can do gives the confidence of feeling a solid foundation beneath the new ideas they are confronting, making the math make sense. If there's a gap between homework and test performance, we take an honest look at WHY--is it test anxiety, or overuse of supports like AI and answer checking? Same problem, with two very different causes requiring different strategies to overcome.

If you're a parent hiring me as a tutor for your student, you understandably want to monitor progress. I can send you lesson summaries that cite obstacles we've worked through, give suggestions on what can be done to support your student outside of tutoring sessions, and recommend additional resources as the need surfaces. (If your student is a legal adult, I'll want their explicit permission to share with you--but that's usually not a difficult ask, and every college will require it as well, no matter who is paying the bills!).

Some feedback from my recent secondary students:

"Learning Algebra was super easy because of you!!"

"Thank you for motivating and believing in me. I will cherish that."

"You're one of the best teachers I've ever had!"

"Thank you for teaching me math for the real world."

Approved Subjects

ACT Math

ACT Math

Over my career I've taught and tutored all of the courses on which the ACT math section is based. In addition to the high school courses that the test covers, I've taught most of the college classes that you might take afterward, giving me the perspective of knowing why certain colleges require certain scores. Finally, my own track record on standardized tests is outstanding. I can help you maximize your score by teaching you to be a more strategic, effective test taker.
Algebra 1

Algebra 1

I've taught Developmental Algebra and College Algebra at universities, and Algebra 1 to honors middle school and on-level high school students. My range of tutoring experience in Algebra 1 ranges from working with students struggling to pass their state assessment or meet a general education degree requirement, to supporting middle school students who want to test out of the course through credit-by-examination. Finally, I have worked with students struggling in other classes (e.g. Chemistry, Physics, Business Math) who just need to rebuild their prior proficiency after years away from math.
Algebra 2

Algebra 2

I've taught Algebra from the level of Algebra 1 through Precalculus at the high school level, and on to College Algebra. It's foundational to all math and most science courses. My range of tutoring experience in Algebra 2 ranges from working with students struggling to pass their high school or meet a general education degree requirement, to supporting middle school students who want to test out of the course through credit-by-examination. Finally, I have worked with students struggling in other classes (e.g. Chemistry, Physics, Business Math) who just need to rebuild their prior proficiency after years away from math.
Calculus

Calculus

I've taught the entire calculus sequence many times, in both high school (AP) and university settings. My students have gone on to complete degrees and work in diverse fields, including medicine, finance, education, sciences, and various engineering fields.
Geometry

Geometry

Geometry in 10th grade was, for me, the class that showed me what math could be. It continues to be among my favorite math subjects to teach and tutor. I first taught Geometry to math majors at the college junior level, and later in a much more sophisticated version at the graduate level. Since moving to secondary teaching I have taught high school Geometry several times. It's one of the few math areas where experimentation can lead to real insight, and pictures can serve to lead students to discover the math.
Linear Algebra

Linear Algebra

In graduate school my research area was in an advanced area of Linear Algebra. After grad school I taught Linear Algebra many times, at several universities. Two of my universities had masters degree programs in mathematics, and I taught graduate courses in Linear Algebra in both programs. I have also tutored many students in a variety of majors who needed to understand Linear Algebra, and directed one student in his masters thesis in Linear Algebra-based techniques in Cryptography.
Precalculus

Precalculus

I have taught Precalculus many times at both the high school and university level, tutoring in both settings. Because I've taught the entire university Calculus sequence (and AP Calculus at high school) I am able to address the course topics from the viewpoint of knowing where they lead. My goal is to have Precalculus be the strong bridge from the "toolbox" background of Algebra to the abstract function focus of Calculus.
SAT Math

SAT Math

Over my career I've taught and tutored all of the courses on which the SAT math section is based. In addition to the high school courses that the test covers, I've taught most of the college classes that you might take afterward, giving me the perspective of knowing why certain colleges require certain scores. Finally, my own track record on standardized tests is outstanding. I can help you maximize your score by teaching you to be a more strategic, effective test taker.
Trigonometry

Trigonometry

I've taught Trigonometry as a stand-alone course in college, and also worked in a tutorial program conducting tutoring sessions exclusively for students struggling in Trigonometry. Teaching in both high school and university I have taught Trigonometry as a topic that comprises over a third of the Precalculus course in the Texas curriculum many times. Finally, in my Geometry classes we have usually 1 to 2 units on trigonometry restricted to right triangles.

Kind and engaging tutor

Met me where I was at a explained concepts I had trouble grasping in several ways until it clicked. Also provided so many excellent review and reference documents to help me in my course. Truly excellent tutor!
