Mark Griffith

Instructor
Hello, my name is Mark! I graduated from Clemson University with degrees in biochemistry & genetics and from the University of South Carolina with a degree in Russian. As a math tutor at many different times in my life, I greatly value the relief & confidence students experience when they actually understand what they are doing! In my free time, I enjoy literature, writing & continuing my Russian studies. I look forward to meeting you at Mathnasium soon!

Marsha Cantrell

Education Director
My name is Marsha Cantrell & I hope to see you soon at Mathnasium. I love teaching numbers. I have taught students from grades 4 through college. Although I have taught for over 35 years, math is always interesting & I learn something new everyday. I would love to help you develop strong math skills and improve confidence in math. Come join us and see how numbers can work for you!

Lindsey Siegel

Training Director
I'm Lindsey - it's nice to meet you! I taught math at Jefferson County High School for 5 years. Friends, family and even strangers cannot believe that anybody would actually want to teach math, especially to high-schoolers, but I think that is because they remember not doing well in math themselves. Even the most difficult problem can be broken down to a simple problem if you look at the core meaning; and that works for anything, not just for math. I believe anybody at any age can learn the skills of thinking that come with knowing how to "do math", but each person does that at their own pace. I am thrilled I get to help students make math make sense at MATHNASIUM!

Jeff Rucker

Owner
Jeff LOVES forecasting success for your child's future! Before opening the first area Mathnasium (in 2011), Jeff was the Chief Meteorologist at NBC Augusta for 12 years. His decision to bring Mathnasium to the CSRA is a logical follow-on to all his previous work as a Navy and broadcast meteorologist. Jeff often jokes that meteorology is 70% math, 20% science and 10% art. “I think I took more math classes in college and grad school than I did weather classes.” Since beginning his broadcast meteorology career back in 1996, Jeff has made school visits and weather education outreach a top priority. From pre-K to high school, Jeff has spoken to hundreds of classrooms all over the CSRA. Anyone who has ever seen one of Jeff’s weather talks (or weathercasts) knows that Jeff loves to teach. Besides making regular visits to area classrooms, Jeff teaches elementary kids at his church, Stevens Creek, and college students at Augusta State. Mathnasium affords Jeff the wonderful opportunity to expand his gift of teaching. “Now I can be in my own classroom all day!” Jeff also believes that math and science expos and fairs are critical to helping all kids understand how important and fun math can be. Jeff has played critical roles in the Middle School State Science Olympiad, SRS Technology Days, and Science Education and Enrichment Day at USC Aiken. “If kids can learn how to think, they will gain confidence to solve problems. Mathnasium is all about building a rock-solid mathematical foundation – we call it number-sense – that leads to confidence and accomplishment in all areas of life, not just in math!” Jeff holds a B.S. in Physics from the U.S. Naval Academy and an M.S. in Meteorology and Physical Oceanography from the Naval Postgraduate School, Monterey, CA. Jeff’s love for math started early! He even earned his high school varsity letter on the math team!

Christine Rucker

Owner + Marketing Director
Christine, Jeff's wife, is his biggest cheerleader and is so excited to be involved with MATHNASIUM here in the CSRA! She is the behind-the-scenes staple that keeps it all together. Christine holds a B.S. in Communications from Old Dominion University. She has worked as a news producer at NBC and CBS in Norfolk VA and at NBC here in Augusta. Her experience line producing local news helps her juggle all the ins and outs of the Centers. As a mother to two college students, Christine knows how to make kids feel comfortable, encouraged and welcomed! She's excited to see you at the center very soon.

Harrison Rucker

Instructor
Nice to meet you, I'm Harrison! I am a Senior at Westminster Schools of Augusta. I am excited to help the Mathnasium students grow stronger and become more confident in math. Nobody should be scared of math and I hope I can help them if they are! Outside of work and school - I love to swim and play basketball. I also love to follow my teams - GA Bulldogs, Chicago Cubs and the Arizona Cardinals. I look forward to meeting you soon.

Jack Tabb

Instructor
Hi, my name is Jack! I attend Westminster Schools of Augusta and I'm so excited to be a part of the Mathnasium team. I don't think math should be scary and I'm here to help our students understand that they've got nothing to fear when it comes to math! In my free time, I love going on walks and playing music. I also love watching sports and am a huge fan of all the major Atlanta sports team and the South Carolina Gamecocks. I can't wait to see you around the Center very soon!

Catherine Newman

Instructor
Hello, my name is Catherine! I'm a student at North Augusta High School. I have always enjoyed math and can't wait to share my passion with the students at Mathnasium. I actually was a student at Mathnasium myself for about a year. I attended to help prepare and practice for the SAT. It's a great place and I'm excited to help your son or daughter! In my free time, I love hanging out with friends and going to the beach.

Colleen Salazar

Instructor
Hello! My name is Colleen Salazar, and I am a graduate from UCLA with a bachelor's degree in Applied Mathematics. I have been a part of Mathnasium for many years - recently, my husband and I moved back home - I'm excited to still be involved with Mathnasium (using our at home platform)!

Our Mathnasium Mission

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
