Improving mathematics programs should be fun.

We are a company that enjoys teaching, learning, traveling, and finding a really good math problem to solve. The members of the Callahan Consulting team draw from their own classroom, teaching, and life experiences to help schools and teachers from around the world with issues ranging from assessments, technology, curriculum, instructional practices, and even difficult parents. We work hard, and we don’t forget to have fun in the process.

If you would like to contact a team member directly, please find our emails below, along with a little bit about each of us.

Adam Green

Known to many for his bottomless stomach, Adam has made a habit of enjoying the finer things in life: bucatini al amatriciana, beouf bourguignon, turkey burgers, unagi and anago, pumpkin curry, and the occasional warm chocolate chip cookie. He’ll have to learn to share because Adam and Mrs. Green are expecting their first child in January 2017.

Adam has been teaching math and science in Sonoma County for six years, teaching everything from Algebra 1 through AP Calculus as well as Conceptual and AP Physics. Since 2012, Adam has been experimenting with new ways to present material in the math classroom with an emphasis on exploratory learning and on application of knowledge. Most recently, he led his math department in the creation of a district-wide standards alignment with an associated Standard Based Grading guideline.

Off campus, Adam has been active at the local college Sonoma State University. In the fall of 2012 and the fall of 2013, he brought his exploratory learning and application emphasis to the college classroom, teaching sections of remedial math to incoming freshmen. During the summer of 2015, Adam was part of a team of local teachers to design and implement a weeklong seminar on integrating Math, Science and Language Arts in the classroom through Project-Based Learning.

Additionally, Adam has been coaching high school basketball, track, and golf for the past six years. He has recently given up his position as the jump coach as well as the varsity men’s and women’s golf programs in an effort to concentrate fully on varsity men’s basketball.
