My passion is to help others!  My personal goal, and therefore my fitness business model is to make exercise FUN.  ZK Group fitness was established in 'Uptown Pitman", a small town where I grew up.  I have been married to Dr. Paul Streck for over 22 years.   We live in Pitman with our three daughters and two dogs. I enjoy a balanced lifestyle which includes my passion to help others through fitness.

I live in Pitman with my husband Steve, we have two children, Melissa and Marco.  I have taught Jackie Sorenson Aerobics and I have always enjoyed group fitness and encouraging people to stay fit and healthy

Although I've passed my ACE® exam in 2011, I started as an aerobics instructor 26 years ago in Rumson, NJ and then took a little time off to raise my family and run a business.  Through being a 'soccer mom' and the move back to Pitman (I was raised and schooled in Pitman) I kept my interest in healthy living and exercise.  I'm excited to be a part of the ZK Family and I hope to make a positive impact in the studio.  "When you encourage others you also encourage yourself."

Health and Physical Education / East Carolina University


I have been teaching group fitness for 27 years and focusing on Zumba® for the last 8 years.  I have pursued fitness certifications through AAAI®, AFFA® and Zumba®.  Zumba® is an international dance/fitness class based on Latin rhythms.  Dance and fitness has been a passion in my life since the early age of 3, when I began my dance training.  I was in my local dance schools' company and earned a scholarship program with Alvin Alley Dance Company.  I earned my BS degree in Health and Physical education from East Carolina University in 1992.  I have been teaching middle school in Washington Township for 24 years where I choreograph the dance and fitness units for my school.  I also have presented dance and fitness in-services for the health and physical education department in WT school district.  I have also taught all types of group fitness classes.  I love to share my passion for dance and fitness with all!

Licenced Zumba® Instructor   CPR/AED Certified        

As a lifelong dancer, I am thrilled to be teaching Zumba at ZK Fit.  I have had “dancing feet” since I was two years old.  Since then I have not stopped dancing!  I have done 16 years of formal dance training at the Bowman School of Dance in many styles including ballet with pointe, tap, jazz, and modern.  I also utilized my dance skills to perform in several musicals in high school and college.    I discovered Zumba three years ago and quickly became addicted.  After attending classes from a variety of instructors, I completed a Zumba Instructor training in 2015 and began working at gyms in the area.  I love incorporating various styles of music and dance in my classes.  My favorite Latin style is Merengue, but you may hear anything from a Motown hit and swing to country and hip hop in my class.  I am always open to feedback and take student requests for a songs whenever possible.    In addition to Zumba, I am a 6th grade teacher at Oak Valley Elementary School in Deptford Township.  I have a Masters degree in Education from Fairleigh Dickinson University.  I love to travel whenever possible and have lived abroad in England and France.  I am also fluent in French and a complete Francophile (you may hear French songs in my class!)  I dream of going to the Zumba convention in Florida and perhaps traveling the world teaching Zumba someday.  I look forward to dancing with you!

'Forever Fit' Program Director

BS in Healh and Exercise Science 


I was born and raised in Minnesota and even though we have lived in Pitman for many years, I will always be a Midwesterner. 

As long as I can remember exercise has been a part of my life. I was a national competitive gymnast by the age of 12. As time moved on, I turned to modern dance. Being fascinated with how the body works and moves, I earned a BS degree in Health and Exercise Science with an emphasis in Nutrition and Modern Dance from the University of Minnesota. My husband Peter and I have been married for over 30 years and have raised three incredible girls who are now all young women. When my girls were little and time was scarce, my exercise routine included walking and running religiously. I have run in races that range from 5k fun runs to completing a marathon. Having had a full-time desk job as a Financial Analyst for 30 years, I have had to tackle the difficulties of balancing time and motivation to incorporate movement into my daily routine. 

Being newly retired and starting a new chapter, I have embraced the idea of mindful movements, focusing on the mind body connection. I am thrilled to join the ZK family and am honored to facilitate Kathy’s program, “Forever Fit”. It is time for us to strengthen our minds as well as our bodies. It is time for us to feel empowered with the knowledge that will allow us to make the best choices for ourselves and our bodies. This precious gift will enable us to live forever fit in mind – body – and spirit. I hope to see you in class.
