ZumbaStrong Class

Jessica Romero: ZumbaStrong Coach

Jessica Romero is an avid dancer, choreographer, and fitness enthusiast.

Jessica took her first Zumba class at 14, and says her instructor (Brenda Johnson) inspired her to share with others what had been revealed to her that day: “the empowerment that comes from working out, love and passion for fitness in a fun environment.”

By 16 years old, she was coaching her first fitness class.

A class with Jessica means:

  • A proper warm up
  • Strength training
  • Moves to encourage the full range of motion.
  • Killer tunes

She injects her knowledge of effective workouts into her invigorating dance routines.

Jessica works to provide a warm nurturing environment for people to grow and hit their personal fitness goals. “Its exciting to get to work and to be able to spend most of my time moving, walking, standing, bending, lifting, instead of sitting all day… to see the faces of my students light up when they hear their favorite song while exercising or when they conquer a new exercise or workout.” 

In her spare time you’ll find Jessica dancing, taking a dance class, teaching a dance class, or working out. She is currently training for a 10k at her local track.

Smart Fit Director

Mandy Oliekan- Smart Fit Director

Meet Mandy Oliekan, Smart Fit Director and Fitness 101 coach at HLF Fitness. She loves painting and all things outdoors, as well as being a competitive mountain biker. Mandy’s love for fitness training began 10-years ago when she first tried weight training. Her personal training mentor told her, “Fitness isn’t a part-time job. It’s a lifestyle choice and, you have to be passionate about what you do as a trainer.”

Mandy says, “I’m helping people feel better, and that’s the biggest reward you can receive when you spend time sharing and educating people about what you love to do.”

When you attend Fitness 101, she emphasizes proper form and doing things step-by-step. She wants you to lift smartly and safely, while taking simple steps to attain a fitness lifestyle.
“Lifting isn’t a temporary Band-Aid,” Mandy says, “It’s a lifetime commitment to yourself. If you’re willing to invest in yourself, I am willing to invest my knowledge to get you there.”

Mandy recently received a senior fitness certification from ExpertRating Solutions, a highly specialized geriatrics status that will afford her new resources to better serve the senior community. This certification reflects Oliekan’s vast knowledge and superior ability to help people over the age of 65 live a healthy, happy lifestyle.
