I have been involved in education, through IBM (as an editor, author, or consultant), or through teaching (five years in NY and seven years in SC as a teacher of mathematics, department chairperson of mathematics, or k-12 mathematics supervisor), for a total of over 30 years. I have a BA in mathematics (UNH), a MS in mathematics (Fordham University), a PhD in mathematics education (Northwestern U), and an executive MBA from (IBM/Harvard U). Additionally, I have taken courses in education, educational technology, or mathematics from IIT, LIU, Adelphi U, Coastal Carolina U, Worcester Polytechnic Institute, Francis Marion U, USC, and Furman U.

I love teaching and especially tutoring (for the opportunity of one-on-one teaching). Additionally, I love mathematics. In that regard, I have edited, authored, or produced mathematics education materials; done years of statistical analysis, and applied mathematics in every job I have had. I endeavor to give each student the benefit of this background in mathematics and education.

My teaching style is to dig into each students difficulties, help each one understand his/her problems, help them eliminate the problems, and to push on with success.

I always try for results as exhibited by the following:

"I thought you would like to know I just completed my MSN and MHA. I couldn't have succeed without your help. Patrick and I still speak of you and our time together. I will be eternally grateful." - former student

Elementary Education:
Elementary Math

Algebra 1

I have taught Algebra 1, Algebra 2, Pre-calculus, Analytic Geometry, and Calculus for many years.

Algebra 2

I studied Algebra at the HS, college, & graduate levels.
I applied Algebra in retail, manufacturing, technology, insurance, and military.
I taught Algebra to students ranging from 6th grade to graduate school.
I tutored students in 6th grade to graduate school in all levels of Algebra.

Discrete Math

I have a BA in mathematics from UNH, an MST in Mathematics from Fordham U, a PhD in Mathematics Education from Northwestern U, and an Executive MBA from Harvard. Additionally I took many courses in technology and business and programming while I worked for IBM for 26 years.


I love Geometry and especially its interplay with Algebra. I have been very involved with Geometry in HS; in my Undergraduate Studies; in my Master's Degree work with linear Algebra, Topology, and the various Mathematics Curriculum groups; and in my Doctoral Work where my very main focus was on how children learn geometry.


I have taught and tutored students pre-Algebra, Algebra, and (the next step) Geometry for many years. I have both undergraduate and graduate degrees in Mathematics. I have practiced Mathematics in a variety of industries.

SAT Math

I taught hundreds of students how to do a better job on the mathematics portion of the SAT. I continued doing so as a tutor. In both instances I had an excellent success rate.


I studied statistics at both the Masters and PhD level
I worked as a statistical analyst for 5 years
I taught statistics and AP statistics for 7 years
I tutored statistics at HS, college, and graduate level for 12 years


My first experiences with trigonometry were in HS Geometry and Advanced Algebra with trigonometry.
I started college with a pre-calculus course that emphasized trig.
Calculus and Analysis in my undergraduate and graduate programs also used a great deal of trig.
Finally, I have taught advanced algebra and trig, pre-calculus, and elementary functions all of which involve a great deal of work with periodic functions.

Exceptional I am pleased to take this opportunity to write a glowing referral for Dr. C. He is a true teaching professional. His willingness to work with my son was greatly appreciated, especially since my mathematical abilities have severely diminished. Over the past summer, Mr. C. tutored my 16 year old in advanced Trig and Pre Calculus. He immediately identified my son’s weaknesses and put together an e ...
