I've taught junior high and high school math, been a computer programmer, professional proofreader, Microsoft Excel expert, and software consultant.

My tutoring methods are individually tailored to the student's interests, needs, level of expertise, inspiration, and goals. I love teaching, and am fun and easy to work with, and receive consistently excellent feedback from my students.

Oh, and I am also an accomplished classical clarinet player and I offer clarinet lessons.

Algebra 1

Algebra is the foundation of just about all modern mathematics (including geometry and calculus) and the physical sciences.

Algebra I is the foundation of Algebra in general.

Plus - it can actually be fun.


After a successful audition, I made 1st clarinet in the New York State All-State band during my senior year of high school. Later on I performed Weber Concerto #1 with my community orchestra after 6 years of private study in which my last teacher told me that I had essentially completed most of a university level clarinet performance major. During this time, during which I was my orchestra's principal clarinet over a 10-year period, I played many (over 50) public performances as part of a woodwind quintet, wind trio, clarinet/flute duet pair, and solo with and without piano accompaniment. I also gave private lessons to a total of 10 junior and senior high school clarinet students during this time.

Computer Science

From 1977 to 1979, I completed the Computer Science undergraduate major requirements from the University of Southern Maine (I had previously earned a master's degree in mathematics and secondary education as well as a bachelor's degree in psychology). I went on to become a professional programmer, systems analyst, project manager, and project management consultant (specializing in software development methodologies, software measurement, and software quality assurance), working in various industries including Utilities, Financial Services, Military Contracting, Educational Contracting, Insurance, Health Sciences, Government Contracting, and Telecommunications. For the past 20 years my specialty has been software measurement, software development methodologies, and Software Quality Assurance.


During my computer science major at the University of Southern Maine, FORTRAN was my most heavily used programming language. I then used FORTRAN professionally over a period of five years in University administration, an electric utility and military contractor.


My favorite course in graduate school was a course in LOGIC. As we know, the most challenging part of a high school geometry class is doing proofs. This is a direct application of logic.


I studied first-order predicate logic in my graduate studies in mathematics leading to my Master of Science in Teaching degree.

Microsoft Outlook

I am currently a Managing Consultant for a small software I have been part of the group for 15 years.

The group is dispersed geographically, and we communicate with both one another and with our clients primarily via email. We have always used Outlook for email, as well as the Calendar, scheduling meetings, and contact management. I also use the Tasks feature and multiple email address management.

Microsoft Windows

In 1983 I began using MS-DOS. I started using Microsoft Windows version 3.1 in 1990, and since have used Windows versions 1995, 1998, 2000, XP, Vista, and Version 7. I use my PC about 10 hours a day and consider myself a power windows user.

Music History

I am an accomplished amateur classical clarinetist. I was principal clarinet in my community orchestra for 10 years, performed Weber Concerto #1 with them, and played in a woodwind quintet, a wind trio, and played extensive duets with a flute player. During the course of this time, I studied Music History informally in order to improve my understanding of the relationship of the music I was playing both among other historic and stylistic forms, plus in relation to the cultural influences of the time and place.


I have always had a fascination for different religions, and have studied them formally and informally throughout my life. I was raised Jewish, and studied Jewish religion in depth. As an undergraduate, i took courses in comparative religion, phenomenology of religion, and other courses in the history and philosophies of Christianity, as well as Islam, Hinduism, and various forms of Buddhism including Tibetan, Vipassana, Zen, and Ch'an. I have also studied (through Anthropology studies) many aboriginal/indigenous religous forms and practices from many cultures.

Visual Basic

I have been using Visual Basic for Applications since 1990 (writing Excel macros). Over the past 15 years, as part of a small consulting group (10 people) for which I am currently a Managing Consultant, I am the only Excel macro programmer in the group, which requires me to frequently write and maintain complex macros for extensive data manipulation and analysis.
