Edward Tkacz, Owner/Center Director

Edward graduated from Drexel University in 1981 with a Bachelor of Science degree in Mathematics. During his college days, Ed accepted a position at a government airport base conducting computer-based airport runway noise level studies, and then moved on to the actuarial department at a major insurance company. Over subsequent years, Ed embarked on a variety of successful business ventures in the recreation and restaurant industries, usually functioning in the role of general manager or proprietor. In his spare time, he worked for H&R Block preparing taxes. He even taught high school math for some time. Ed knows that whether it is taking inventories at his restaurants, performing cost-analysis at his bowling center, or grading student papers, it all involves working with numbers! Now, with over 30 years of experience under his belt, Ed can fully appreciate the importance of having a strong foundation in mathematics. Unfortunately, many kids today lack the basic math skills to grasp the principles of algebra and beyond. In 2006, the National Center for Education Statistics found U.S. students placed below average in math and science. Furthermore, the specialized instruction necessary for children who have a particularly difficult time with math is usually unavailable. This is where Mathnasium can help! Independent studies have shown Mathnasium's methods can significantly increase your child's math skills, understanding of math concepts and overall school performance. Ed always had a passion for math and, combined with his enjoyment of working with children, this opportunity seemed like a perfect fit. Winner of Mathnasium's - Best Instructional Miracle Award 2010.

Pamela Tkacz, Owner/Administrator

Pamela has been married to Ed for 32 years. In addition to raising three sons, Pamela has worked in the Medical field for over 30 years, and continues to provide private care for the elderly on a part-time basis. Also very fond of children, Pamela was a regular PTA member and home room mother at her son's elementary schools. She assists Edward with the administrative functions of the business so he can fully dedicate his efforts to teaching. Through their Mathnasium Learning Center, Ed and Pam hope to make a difference in the futures of children for many years to come.
