About William

I am an extremely talented and creative scientist who is now semi-retired from a 40+ year career as an analytical chemist, x-ray spectroscopist and electron microscopist. Though my degree is in chemistry, I feel equally adept at physics and mathematics. I am also the only person I know who speaks and writes grammatically perfect English. I am also the sort of person who never reads a book without also having a dictionary close at hand. If I encounter an unfamiliar word, I look it up immediately, and write the definition in the margin of the page on which I encountered it.

My tutoring "style" is to drop subtle hints to the student thereby bringing him or her into the discovery process. Giving the student the opportunity of having a "Eureka" moment is, I believe, a great way to boost his or her confidence, and also to turn him or her into a "lifelong learner" by choice.

In my brief career as a tutor, I have had students anywhere from Grade 2 to college seniors. All have responded well to me as a tutor and as a human being.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

Algebra 1

Well qualified to teach the techniques of expressing one variable in terms of another (or others), the graphing of functions, etc.

Algebra 2

It is conceivable that a person can take many courses in calculus, and never use it again (unless he or she is a physicist or engineer). I dare say, however, that a person will use algebra in one form or another every day of his or her life. Yes, it's that important!

American History

I am a serious student of American History, especially of the Civil War period. I am willing to criticize US presidents, senators and/or supreme court justices when they make decisions that are bone-headed (such as the Dred Scott decision).


I have helped many students not only pass, but excel in the ASVAB test.

Bible Studies

As a life-long Christian the Bible is something with which I am well acquainted. I do, however, realize that the Bible is an ancient document and that many of the sources on which modern translations are created do not agree with one another. Through my in-depth studies on the university level I realize that there is a discernible chain of thought in the Prophets, for example, that improves with passing generations, from Amos to Trito-Isaiah. My goal, therefore, would not be to proselytize potential students but to emphasize the fact that the Bible is a document, worthy of study and, on occasion, worthy of criticism.


General chemistry including, but not limited to, organic nomenclature, acid-base reactions, concentration calculations, phase transformations, etc.

Elementary (K-6th)

I have been substitute teaching K through 12 in the Aliquippa and Hopewell Area school districts since November, 2011. It's something I know how to do!

Elementary Math

Without that solid foundation laid in elementary math (basically arithmetic) the ability to advance into algebra, trigonometry and calculus would be rather difficult. Once, however, those most basic of concepts are conquered, that transition is easy. At least that's been my experience.


One of my former colleagues told me that I have the largest vocabulary of anyone he knows. This is not something I necessarily tried to achieve on purpose but I must have a particularly good memory and have retained all of that information they taught us in English grammar classes.


Teaching a person to speak English has got to be one of the headiest thrills a tutor can have. English is not an easy language. The tutor must be a person of infinite patience, a quality I do possess.


Helping people achieve their GED is the proudest part of my work up till now. In this society the HS diploma (or successfully completed GED exam) is the gateway to college and beyond. I am prouder, perhaps, of my GED students than any other group because so many of them were convinced they were stupid, or losers, and I showed them otherwise.

General Computer

I gained my computer skills on the job during the 1990s. Since then I have had the opportunity to instruct many people, young and old alike, in "all things computer" and especially in MS Word and Excel.

All the students I've ever had in this subject are now as computer literate as anyone you are likely to encounter.


We live in what appears to be a three-dimensional universe. The ability to analyze mathematically the shapes found in nature, for example, is a profound gift. Helping young people do this is something in which I am experienced and from which I derive much pleasure. Watching each student having his or her "eureka" moment, when some concept that seemed so difficult the day before all of a sudden becomes clear is an experience like no other.


Parts of speech, good sentence structure, active and passive voices, when to use "complement" instead of "compliment", etc.


The ability to create and appreciate literature is one of those things that separates us, homo sapiens, from the other beasts with whom we share this planet. "Huckleberry Finn", "A Christmas Carol", "Crime and Punishment", "Don Quixote", etc. have the ability to deeply touch the reader and take him (her) to places he or she never knew existed.

Microsoft Excel

Microsoft Excel is the greatest computer program ever and I have used it to track inventory, track completed chemical analyses, track my bank accounts. And I have taught other people to do the same.

Microsoft Word

Microsoft Word (and similar products such as the Open Office suite) is a powerful word processing program that allows the user to create "professional" looking documents at his or her own computer. It is absolutely necessary for anyone planning on doing any writing to master this wonderful program.

Music History

Music is, perhaps, the greatest of all my passions. I have been a serious student since age 12. I have played the violin (until I broke my elbow), and have attended the University of Miami's summer band and orchestra camp where I received a prize in recognition of how far my understanding of music theory progressed during those weeks. In my own collection I have recordings of music by Hildegard von Bingen all the way through to Igor Stravinsky, and I love it all.

Organic Chemistry

My bachelor's degree in chemistry included having to successfully pass 5 quarters of organic chemistry and a laboratory sessions associated with the classes.


Physics is arguably the most important subject of all. The fate of the universe itself will likely be ascertained by physicists. Everything from the motion of planets around stars to the nature of images in concave and convex mirrors, to the wonderful sounds of stretched strings in musical instruments can be explained by the mathematics of physics.

And I love it all!


The math portion of the Praxis is that sort of stuff which will come in handy every day of your life. But you need to know the concepts first. I can help.


The transition from arithmetic to algebra can be a scary one for young people. I have helped many students make this transition successfully, both in one-on-one tutoring sessions and in front of the classroom.


The transition from linear algebra (for example) can often be very difficult for young people to grasp. My aim is to make it as easy as I know how.


In my previous life as an analytical chemist, I was called upon to write procedures, SOPs, STMs and similar documents. I also had the opportunity to proofread items submitted by my colleagues. I'm good at it.


In and of itself, the ability to read is not as important as reading with understanding (underline "with understanding"). The role of the tutor has to be making certain that the person being tutored has read with understanding.

SAT Math

The sort of math skills emphasized on the SAT exam are those which one will likely encounter every day of his or her life. Mastering these skills will enable the student to succeed in any field of endeavor.

SAT Reading

Reading with understanding is something that will serve anyone well, whether his (her) goal is passing the SAT with a high score or being a valuable employee in industry or academia.

SAT Writing

The SAT test specializes in that type of writing where everything, including the order of sentences in a paragraph, follows a logical progression. It aims, above all things, to ascertain whether the test taker has a sense of how things ought to "flow." It is the sort of writing to which we all aspire.

Special Needs

In my career as a substitute teacher, I was often assigned to special needs classes. In many ways, I enjoyed being with them more than I did with the young people who had no such needs. There is something about my personality and theirs that created a situation where everything "clicked," and we always had a good time.


Teaching people how to read and write English is one of the most important things we can do to show our good manners. I have helped any number of people pass the TOEFL and their gratitude is is payment enough.


A good grasp of trigonometry is essential to understanding the physics of motion and the resolving of vectors into their components. These are the sorts of things I would love to introduce to young people.


I'm the type of person who never reads a book or magazine without having a dictionary handy. If I encounter a word I've never seen before I look up its definition and add it to the margin of whichever book or magazine I happen to be reading. In this way my vocabulary has become very impressive over the years.

World History

For good or ill, we are the end product of societal forces that arose in the Nile, Indus and other flood planes thousands of years ago. I want to understand not only what has happened over the last five millenia or so, but why things happened the way they did.


It is always a pleasure to encounter good writing. I have read many fiction and non-fiction books that would never have been published if I had been the person to whom the manuscript had originally been sent. It drives me up a wall when people write "complimentary" when they really mean "complementary."
