Genny Pinzon, Health Promotion Program Manager at Always Active

“Better light a candle than complain about the darkness” ― Ajahn Brahm

I began my career as an instructor in 2010. I started by teaching Zumba Gold to older adults and felt in love with the possibility I had to impact their lives through movement.
Now that I lead the Always Active program, I have the opportunity to incorporate movement, strength, cardio and flexibility in one class. It is rewarding and powerful to see participants who could not move well, regain their independence, build a community and continue to live their lives to their full capacity. I invite you to try a free class! Please visit:

Luz Villaneuva, Always Active Program Specialist and Instructor

Luz has been involved in sports her whole life. She began her career in Nutrition, graduating from the California Culinary Academy in 2004, before transitioning into Fitness. At 19, Luz suffered a spinal injury and spent five years recovering. During that time, she worked in the first multi-disciplinary wellness center in the country; where participants integrated nutrition, yoga, medical lectures and art classes into their comprehensive physical therapy. Aiding her own recovery, Luz studied to become a yoga teacher while working. In 2012, she received her first fitness certification from Yoga To The People SF, which is a donation-based school.  From there, making wellness programs accessible to everyone became her primary focus. She began teaching all levels- from fit to frail. Eventually, her ability to modify exercises became her specialty. She returned to San Francisco and found that Always Active was the perfect fit. She enjoys teaching classes bilingually and for all abilities.

“San Francisco is my hometown and I am honored to be able to serve its communities. “

Kevin Cordero, instructor and Always Active health promotion program assistant 

“The moment you stop learning is the moment you start dying.” – Albert Einstein

I graduated as a Kinesiology major focused on therapeutic studies.  As a student, I began working with older adults as part of my internship to educate them on fall prevention methods and help them strengthen their bodies in order to maintain their independence.  Throughout the time I spent training older adults, I witnessed all the progress they achieved not just physically, but also their emotional and social health which overall improved their self-confidence. Working with this population challenges me to think outside the box and consider how the body works as we age and how I can help them adapt to the needs that comes with age. Every day is different when it comes to working with older adults.  Each has their own capabilities and piece of knowledge to share which is something I can take with me in life.

Certifications: BS Kinesiology, NASM, CPR/First Aid/AED, ASFA, FAI

Sue Mittelman, Always Active regional coordinator and instructor

I wanted to work with seniors around fitness and active aging after watching my mother struggle with severe osteoporosis in her final years.  Fortunately, I discovered the Always Active program was looking for volunteers and willing to train.  The timing was perfect.  Dr. Christian Thompson (USF) and Jim Spinelli trained me to lead general group strength and flexibility classes.  I received additional training to lead Fall Prevention classes. That was nine years ago.  For the past 7 years I have been on the staff of the Aquatic Park Senior Center and the Always Active Program as a regional coordinator and exercise leader. 

Certifications: I am certified through the American Senior Fitness Association and the Functional Aging Institute.
