Jennifer Westendorf

Jen’s fitness career began early on as a recreational participant in both school and community programs. Over the years, the benefits of fitness always were at the forefront even as she transitioned into the work force. So much so that Jen merged her passion for health and wellness into a career over the last 10 years while living in Los Angeles, as the Assistant Director for Fitness & Wellness at Loyola Marymount University.  Initially receiving her Mad Dogg (Spinning) and Barre Physique certifications in 2008, she also holds certifications in Schwinn Indoor Cycling, AFAA Group Exercise, TRX, and is a 200 hour RYT.

Holly Visser

Corporate Yoga Instructor

Holly was exposed to yoga when a fellow athlete recommended it for recovery from a knee injury.  She was soon balancing her biking, running, and swimming, with yoga as well. In time, she has improved her skills in  discipline as well as staying mostly injury free. In addition, she benefits from a greater sense of calm, and feels as though she makes more thoughtful life decisions from the time invested on her mat.

Holly received her training through Holy Yoga International and is certified as an H-RYT at the 200 level. She has her ACE group fitness certification and Yogalates Specialty Certification. It is her priority to put safety and proper alignment first in each class setting, but to also include elements of creativity and playfulness to enlighten the beginner as well as lighten the spirit of each in attendance. You will hear the phrase “lots of grace” in class often. Whether new to the many styles of yoga or experienced…Holly  knows that we all bring something different to the mat every time we practice.

Monica Reyna

After experiencing life at 240lbs I decided to shift my behavior and join a gym. Participating in group fitness classes had such an impact on my life that stepping into an instructor role was a natural “next step”. Fast forward 20 years and two beautiful daughters later, and Fitness and whole human wellness is an incredible lifestyle and continued journey! Knee deep in healing techniques, meditation, Tai Chi, vibration shifting, personal training and feeling good, my life is amazing and continues to unfold perfectly! So appreciate Allegro Coaching for welcoming me!

Always being active in sports during his high school years, the two-week trial membership was all it took to reignite his athletic fire. “The team at Allegro empowered me to create long-term change in mind,body, and spirit. I discovered a community of like-minded people and feel blessed to have met them all.”
With the encouragement of staff at Allegro, Henry has worked to attain his Group Exercise Certification through AFAA (Athletics and Fitness Association of America). His hope and goal is to give back to the community that he has come to enjoy so much.
