Center Director/OwnerDan Gehlbach, Center Director/Owner

 

*Mathnasium Master Certified*

Thanks for visiting our website! My name is Dan Gehlbach and I serve as the Center Director as well as own the West Des Moines Mathnasium location. Please don’t hesitate to call me or fill out the form above to find out more about how we can help your child. And learn how to try us out for FREE!

I am a native of Urbandale and graduated from UHS. I have lived all over the world but settled back in “new” Urbandale in 2006. Before opening our center in West Des Moines in early 2011, I was in the auditing field and a Certified Internal Auditor. I have an undergraduate degree from the University of Kansas and a MBA from Arizona State University. I have worked as a high school teacher overseas, a corporate auditor for the big casinos in Las Vegas, and in the insurance and healthcare industry.

I have a wonderful wife, Staci, and 2 fantastic daughters. My oldest is now a 3rd grader in the Waukee School District as well as a proud Mathnasium student. My youngest is 6 and is in kindergarten. She can be seen around the center grabbing as many Smarties candies as she can.

After learning more about Mathnasium and seeing what it offers kids, I took the risk and started Mathnasium of West Des Moines 6 years ago. It has been tremendously rewarding to help kids in our community and see them reach their potential. We have hundreds of amazing success stories as a result of our Passionate Instructors, the Inspiring Learning Environment, Teaching Style and Curriculum at Mathnasium! Let Mathnasium help your student! 


MartinekLarry Martinek,

Chief Instructional Officer, Developer of Mathnasium Program. 

Larry has spent his entire career finding a better way to teach math. From inner city to public schools, to acclaimed magnet schools, to leading private and parochial schools, Larry has served as both a classroom teacher and as an educational consultant. He has designed curriculum, teaching strategies, and teaching materials designed to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting student’s ability to “do” math, thereby increasing student’s math scores and feeling of self-worth. Larry is the developer of Mathnasium’s educational program – one of the most comprehensive and innovative curriculums ever produced for teaching math.

While Larry is not an Instructor at our Center, He is a valuable asset we can call on to ask about specific students scenarios for guidance and advice. This has helped to make visits more productive and enjoyable for many of our students.

Lead InstructorGreg Turnbow, Assistant Center Director

 I love working at Mathnasium because of the kids. Seeing their eyes light up when they get a new concept or raise their grades gives me satisfaction and joy. Math is just a problem to be solved, it's a matter of finding the solution. 

Favorite Number: 42 - due to Jackie Robinson and Hitchhiker's Guide to the Galaxy

 

 

Lead InstructorWill Thornton, Lead Instructor

Favorite Number: 3 - Because the School House Rock song for the number 3 has been stuck in my head since I can remember. Also, the rule for divisibility by 3 still blows my mind - its simple yet easy to apply to large numbers.

Lead InstructorJuliana Varner, Instructor

I am currently a senior at Drake University with an Actuarial Science/Finance major. I like Mathnasium because I want kids to see that math isn't as hard as they might think. My favorite part is when a kid goes from saying "I can't do this" to "Oh that's it? That's easy!"

Favorite Number: 37 - Because it is a prime number made up of 2 two other prime numbers. 


Lead InstructorMichael Bellinghausen, Instructor

I love working at Mathnasium because helping kids with math is something I have done and enjoyed. Seeing kids understand how math problems work and have confidence to do them gives me great pride. 

Favorite Number: 4 - Because my first clear memory is my 4th Christmas. That has always stuck with me and I still have the present I got.  


Lead InstructorMichael Stanfa, Instructor

I am a Drake graduate currently working in technology at Principal. In my free time I like running, camping, and spending time with friends. 

Favorite Number: 19 - Because it is a prime number and a number I used to wear in sports. 


Lead InstructorKelsey Einertson, Instructor

Favorite Number: 19 - Because it is Jonathan Toews' jersey number and it's a prime number.

Favorite Number: 2 - Because it is the first even number.  


Lead InstructorHenry Parker, Instructor

I am a currently studying physics and computer science at Drake. Sounds fun, I know, but it is!

Favorite Number: 20 - Because I am a big fan of even numbers. I always like the radio volume or car temperature on an even number - weird, I know! Also, when I was younger, everything was the number twenty: my bus number, my cubby number in elementary school, and my soccer jersey number. 


Lead InstructorNichole Greseth, Instructor

I am a former middle school and high school math teacher with a degree in math education. I am currently a nursing student at DMACC. In addition to Mathnasium, I also work at Blank Childrens Hospital. In my free time I like to go on bike rides with my dog, Zazu .

Lead InstructorBernice Yeoh, Instructor

I am a senior at Drake University majoring in Actuarial Science and Data Analytics. Math has always been my favorite subject ever since I was little. Getting to work with kids and teach them math is my greatest pleasure

Lead InstructorLauren Walker, Instructor

I graduated from Iowa State University with a degree in Meteorology but then went on to work in the insurance industry. Math has always been my favorite subject and I couldn't think of anything better than helping kids find the fun in math! 

 

Favorite Number: 0 - Because it is simple yet powerful. Zero by itself is nothing, but it can have such a profound impact on other numbers by making them much bigger or much smaller.
