Hello, we're the Gehman Family!


Isaac Gehman, Center Director (Right)

Isaac is a 2016 graduate of Rose-Hulman Institute of Technology (BS, Civil Engineering).  Prior to Mathnasium, Isaac worked in Anchorage, AK as an engineer with a global construction firm.  While there, he enjoyed rock-climbing, skiing, and salmon fishing - things not commonly available in the Hoosier state.  After opening Mathnasium of Brownsburg in 2018, the Gehmans worked with Ron Smith (below) to help Ron transition to retirement and to keep Mathnasium of Zionsville going strong!  Isaac began working full-time as owner/operator at Zionsville in Fall of 2019.

Wendy Gehman, Education Director (Left)

Wendy is the Education Director at Mathnasium of Brownsburg.  Prior to Mathnasium of Brownsburg, Wendy was an elementary teacher for Vigo County School Corporation where she taught a combined 4th/5th Grade, gifted and talented class at Sugar Grove Elementary School.  Besides the hundreds of children she's educated in her classroom over the years, she is the proud mother of two boys.  Samuel (youngest), a 2019 Notre Dame graduate, lives in Chicago and works in corporate finance.  Isaac (oldest) joins Wendy as a co-owner at Mathnasium, and you can read more about him below!  During the school day, you can find Wendy teaching 4th grade in Zionsville's Eagle Elementary School.

Drew Gehman, Co-Owner (Middle)

Drew is proud to work alongside his family as Center Director at Mathnasium of Brownsburg and co-owner at Mathnasiums of Brownsburg and Zionsville.  A 1985 graduate of Rose-Hulman Institute of Technology (BS, Electrical Engineering), Drew brings a rich blend of education, technical expertise, and community involvement.

Ronald Smith, Owner Emeritus

Ron is the owner Mathnasium of Zionsville

When you’ve got 17 grandkids – that’s right, 17!  – you get a real sense of how kids tick: what makes them happy, what motivates them, what helps them succeed. When Ron's granddaughters enrolled in Mathnasium of Carmel, he expected just another tutoring service – until the day he told them they wouldn’t be able to make it in for a learning session. They were so disappointed, they made Ron PROMISE to make it up by taking them to extra sessions! Ron was so inspired by Mathnasium's work, he started Mathnasium of Zionsville.

In 2019, Ron felt a calling to spend more time with those same 17 grandkids, and chose to sell the center to the Gehman family (above), owners of Mathnasium of Brownsburg.  You can still spot Ron from time to time, dropping off his granddaughter for a session or in the Carmel/Zionsville area doing whatever Ron does!

Abby Fitzwater, Assistant Center Director 

Abby is a private math tutor

Who understands difficulties with math in school better than someone in school? I am a senior at Butler University studying secondary math education, mathematics, and math is my favorite subject! That doesn't mean it has always been easy. But getting successfully through the tough problems is really what it's all about. I love being at Mathnasium because I can provide the help our students need, even if all they need is support from someone who isn't their parent. I hope to see you soon!


Zachary Brown, Lead Instructor 

I'm Zach. I was a wrestler at Ashland University and graduated with a degree in Computer Science and a minor in math. I work at Zionsville Middle School as an Instructional Assistant and an assistant wrestling coach. When I was growing up, math wasn’t the easiest subject and some of the topics were rather confusing, but because of great teachers who really love to help students understand how to do the hard problems I was able to make that a part of my degree. Now I’m working to be just like those helpful teachers and hope that students can have an even better experience than I did!





Jim Eggleston, Lead Instructor 

 I spent 12 years in the US Air Force after graduating as an engineer from Purdue University way back in 1982. Then I worked for a couple of government contractors for 15 years helping provide fighter aircraft and combat radios to our armed forces.  Then, I lost my job as our company downsized during the recession, and at 50 years old I was having difficulty finding an engineering job in the Fort Wayne area.  So I decided to transition to teaching as many in STEM jobs have done, and after finishing my certification program at Indiana-Purdue Fort Wayne, I found a middle school math teaching position at a small, parochial school.  However, after only two years of teaching there and I moved here in the Carmel/Indy area.  Although I enjoyed teaching in a classroom, it was a bit exhausting, so I decided to try helping kids with math in a different environment – after school.  I saw a newspaper article a few years ago about Ron’s decision to start a Mathnasium in Zionsville.  I read some more about Mathnasium and it sounded great, and as they say, the rest is history.  I always did okay in math through college, but I did have other college courses where I struggled a lot, so I know what it feels like to not understand something someone is trying to teach you.  Now I can really enjoy helping kids who are struggling to understand math or help them to know more.  Hopefully I can help you! 


Abby O'Meara, Instructor 

Hi I’m Abby and I’m majoring in Math at IUPUI. I genuinely love helping kids learn and connect things together until they really “get it.” Because of that, I know teaching math is as much about knowing how to teach as it is about actually knowing math. I have had a lot of experience with math being frustrating, even though I’m a math major.  I know that kids think different, and I have had years of experience with adjusting material to make sense on an individual basis. I understand that not everyone loves math, but as I’ve grown up I’ve learned how useful math can be in real life. I hope I can help you enjoy math as much as I do.
