I have been tutoring since my early college days some 25+ years ago. I started tutoring as a means for me to study and assure myself I understood the material for my subjects. My early tutoring was just that tutoring in the subject I was taking.

I have always enjoyed math, and as a parent of 4 school age children over the past several years, I have had my share of experience in the tutoring mode for Grade school through High School math classes. With having my degree in Chemistry and minor in Math as well as my love for math, I tend to be the one my children come to most for help with their math and or science classes.

Out side of the home, I have also enjoy working with youth in 6th Grade math through Pre-Calculus in High School as well as every course in between. Over the past couple years, I have helped many students get caught up, stay caught up, and pass their math classes.

As a tutor, my philosophy is if someone can explain it, they most likely understand it, and with this mentality, I work to get students to explain to me what they are doing and why, so I know they can do it when they are on their own. I tend to guide students into discovering the right way to solve problems instead of telling them how to do something. I am also willing to allow students to try their way and discover why it doesn't work. I feel this builds confidence as well as helps in memory retention.

I work diligently on avoiding the straight memorization of equations, facts, or processes... I seek to have students understand what they are doing. If they don't understand it, they are liable to forget it come final exam time or in future courses.

If you have any questions, please don't hesitate to contact me...

ACT Math

When choosing between the ACT and SAT, be aware that the ACT is more widely used in the Midwestern, Rocky Mountain, and Southern United States, while the SAT is more popular on the East and West coasts. Recently, however, the ACT is being used more on the East Coast. Use of the ACT by colleges has risen as a result of various criticisms of the effectiveness and fairness of the SAT.

In preparing for the Math section of the ACT be aware section is the 60-minute, 60-question mathematics test and contains:

- 14 covering pre-algebra
- 10 elementary algebra
- 9 intermediate algebra
- 14 plane geometry
- 9 coordinate geometry
-4 elementary trigonometry

Calculators are permitted in this section only. The calculator requirements are stricter than the SAT's in that computer algebra systems are not allowed; however, the ACT permits calculators with paper tapes, that make noise (but must be disabled), or that have power cords with certain "modifications" (i.e., disabling the mentioned features), which the SAT does not allow. Also, this is the only section that has five instead of four answer choices.

ACT Science

Choosing between the ACT and SAT, be aware that the The ACT is more widely used in the Midwestern, Rocky Mountain, and Southern United States, while the SAT is more popular on the East and West coasts. Recently, however, the ACT is being used more on the East Coast. Use of the ACT by colleges has risen as a result of various criticisms of the effectiveness and fairness of the SAT.

The science reasoning test is a 35-minute, 40-question test. There are:

- seven passages each followed by five to seven questions.
- three Data Representation passages with 5 questions following each passage
- 3 Research Summary passage with six questions each
- one Conflicting Viewpoints passage with 7 questions.


Chemistry, a branch of physical science, is the study of the composition, properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds.

Chemistry is also concerned with the interactions between atoms (or groups of atoms) and various forms of energy (e.g. photochemical reactions, changes in phases of matter, separation of mixtures, properties of polymers, etc.).

A high school and/or college General Chemistry Course would typically include an over view of the basic principles (or disciplines study within chemistry).

These principles would include:

- Theoretical Chemistry
- Computational Chemistry
- Inorganic Chemistry
- Organic Chemistry
- Analytical Chemistry
- Electro Chemistry
- Nuclear (or radio isotope) chemistry
- Physical Chemistry
- Bio Chemistry

Typically, a General Chemistry course would focus on the first 5 principles and briefly touch on the remaining 4.

Elementary (K-6th)

Tutoring Elementary age children requires much more than teaching math, reading, writing, and/or social studies.

It is my firm believe that the vast majority of the time is and should be spend on building up confidence and self esteem. It is the confidence in ones self that motivates students to try more, to do more, and to achieve more.

My experience in tutoring younger children comes primarily from working with my own kids. I've helped with Spelling, Social Studies, Math, Science, and English. I have also assisted with 4H projects, Bible Studies, and Science Fair projects.

In addition to course work, I have also coached soccer for grades 1 through 4, and I have chaired and managed large motor skill activities for VBS.

Along with tutoring general topics, I try to shower with praises and lead them into finding the answers to the questions or problems on their own so that they know they can do it and have the courage to try there best at everything they do.

Elementary Math

Although I do not personally like the current Everyday Math curriculum, I understand that different students need different paths to correctly solve a problem. Not everyone understands one thing the same way.

Because I have see Everyday Math as a curriculum of choice in so many districts, I have taken it upon myself to thoroughly understand it. I have been working with it since my oldest daughter (now 10th grade) was in second grade and first started struggling with her math. I have also worked my 7th grade son through the curriculum and I'm currently working with my 3rd grade daughter.

My own personal success story with elementary math tutoring would be my oldest daughter. Just before we moved to Rochester, she was in a combined 4th grade class. This was a bad situation for her because there were too many students in the class and there was very little one on one or small group interaction with either teacher. My daughter went from struggling with math yet understanding it to having no clue as to what she was supposed to do. Her first year in Rochester she started 5th grade behind and doing poorly in class. I started working with her on a more daily basis, I retaught her what she was supposed to learn in 4th grade, and caught her up in 5th grade. She passed 5th grade math with outstanding marks. She excelled in 6th and 7th grade. At the start of 8th grade, she skipped a class and was moved to an accelerated 9th grade class. She as been accelerated since and is doing great. Math is once again one of her favorite subjects.

Elementary Science

Science in Elementary School is a general overview of a very broad range of topics and experiments. The basic goal through science in elementary school is to teach fundamental techniques in the following:

- abilities necessary to do and understand scientific inquiry

- properties and position of objects and materials

- characteristics of organisms, life cycles, and environments

- properties and objects of earth and sky as well as changes observed

- understanding science .vs. technology and natural .vs. man made objects

- personal health, population, and environments

- how science and technology relate to human endeavor


Geometry is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space.

Topics typically covered:
- Basics of Geometry
- Reasoning and Proofs
- Perpendicular and Parallel Lines
- Congruent Triangles
- Properties of Triangles
- Quadrilaterals
- Transformations
- Similarity
- Right Triangles and Trigonometry
- Circles
- Areas of Polygons and Circles
- Surface Area and Volume


To me, Logic is a specific way of thinking. It is used throughout computer programing as well as electronics.

My training on this thought process comes from both course work as well as hands on work in electronics, computer programing, as well as courses specific to logic.

I am fluent in reading schematics and tracing out the outputs of AND gates, OR gates, NAND, as well as NOR gates. I'm fluent in Binary System Logic and its operations.


As far as photography is concerned, my dad deserves the credit for the start of my passion. He got me started when I was in grade school with a Kodak instant camera, and in junior high with his SLR. He taught me about lighting, selecting the subject, and framing the photos. He taught me that a picture is more than just a picture it is a memory that can last a lifetime. It was through his praises of my good work as well as his honest critiques of my not so good work, which truly got me started with my love for the art of photography. In high school, I took a photography class, and photography has been a hobby and a passion ever since. I have been shooting now for over 30 years.

With the digital era, I find I have as much of a passion for the post-production or photo enhancements as I have always had for the taking of the photo itself. I continue to read to learn more because I love to experiment with various techniques both with the camera as well as the computer.

My primary focus over the past few 6 – 8 years has been in Action Shooting; however, I have recently started to rent studio time and bring my focus into the studio and on portrait shooting.

Though I tend to have a camera with me most of the time, there is life outside of photography. I have been blessed with a loving wife and four great children (three daughters, a 16 yr old, 9 yr old, and 6 yr old; and a 14 yr old son). We moved to Rochester in 2006 and have truly enjoyed making it our home. We spend much of our time at either the Rec. Center Ice Rink with 3 figure skaters, or at the soccer fields with 2 aspiring soccer stars and their coaches.

I look forward to tutoring you or your student in hopes that you or they can create treasured photos that you will enjoy, as will your children and your children’s children.

Physical Science

Physical science is the study of physics and chemistry of nature. From the materialist and functionalist viewpoints it overlaps the life sciences where ecology studies the evidences of historical facts and evolution. The foundations of the physical sciences rests upon key concepts and theories, each of which explains and/or models a particular aspect of the behavior of nature.

General principles of the physical sciences would include the basic principles of:
- Physics
- Chemistry
- Astronomy
- Earth Sciences


Physics is a natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force.

Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms of other sciences, while opening new avenues of research in areas such as mathematics and philosophy.

Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products which have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.

A general high school Physics Course will cover the basic principles of physics including:

- Motion
- Gravity
- Energy
- Wave and Sound Theory
- Electricity and Magnetism
- Light Theory

SAT Math

In choosing between the SAT and the ACT tests, you should be aware that historically, the SAT has been more popular among colleges on the coasts and the ACT more popular in the Midwest and South. There are some colleges that require the ACT to be taken for college course placement, and a few schools that formerly did not accept the SAT at all. Nearly all colleges accept the test.

The Mathematics section of the SAT is widely known as the Quantitative Section or Calculation Section. The mathematics section consists of three scored sections. There are two 25-minute sections and one 20-minute section, as follows:

- 25-minute sections is entirely multiple choice, with 20 questions.

- 25-minute section contains 8 multiple choice questions and 10 grid-in questions. For grid-in questions, test-takers write the answer inside a grid on the answer sheet. (Unlike multiple choice questions, there is no penalty for incorrect answers on grid-in questions because the test-taker is not limited to a few possible choices)

- 20-minute section is all multiple choice, with 16 questions.

The SAT has done away with quantitative comparison questions on the math section, leaving only questions with symbolic or numerical answers.

New topics include Algebra II and scatter plots. These recent changes have resulted in a shorter, more quantitative exam requiring higher level mathematics courses relative to the previous exam.

Calculator use:

Four-function, scientific, and graphing calculators are permitted on the SAT math section; however, calculators are not permitted on either of the other sections.

Calculators with QWERTY keyboards, cell phone calculators, portable computers, and personal organizers are not permitted.

With the recent changes to the content of the SAT math section, the need to save time while maintaining accuracy of calculations has led some to use calculator programs during the test. These programs allow students to complete problems faster than would normally be possible when making calculations manually.

The use of a graphing calculator is sometimes preferred, especially for geometry problems and questions involving multiple calculations. According to research conducted by the CollegeBoard, performance on the math sections of the exam is associated with the extent of calculator use, with those using calculators on about a third to a half of the items averaging higher scores than those using calculators less frequently. The use of a graphing calculator in mathematics courses, and also becoming familiar with the calculator outside of the classroom, is known to have a positive effect on the performance of students using a graphing calculator during the exam.

Study Skills

Every person is different. People study and learn at different rates, with different styles, and with the use of various aids.

There are key points that need to be addressed to teach someone good study habits, time management skills, as well as organizational skills.

I would consider these to be:
- Keeping all tasks assigned on a list in one location with due dates to aid in prioritizing.
- Determine what is the best location to study.
- Determine how long student can study effectively before a break is needed.
- Getting in the right frame of mind before starting assigned projects.

I have personally struggled with organizational skills, motivation, as well as location in the past. It took me some time to figure out my correct techniques, and I would like to help your student figure out theirs.


Trigonometry is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves.

A Trigonometry Course would likely cover:

- General Overview (including definitions)
- Standard Identities
- Angle Transformation Formulas
- Common Formulas
> Law of Sines
> Law of Cosines
> Law of Tangents
> Euler's Formula

(As a side note, depending on the school district's chosen curriculum, I have seen Trigonometry taught in both Algebra II and PreCalculus instead of having Trigonometry offered as its own course.)
