Jackie Wise,
Always Active/Fall Prevention Instructor

Jackie was born and raised in sunny San Diego and relocated to Sacramento after living in San Francisco for 27 years. At 40, she realized that life isn’t about perfection; it’s about progress. The progress of growing and turning challenges into learning opportunities and being empowered by what one does. For her, this progress was rekindled when she resumed an active lifestyle. She began her second act, working at a women’s fitness center in my Outer Sunset neighborhood in San Francisco, CA. Before long, she was teaching circuit classes and managing the gym. She discovered Zumba Fitness in 2007 and was hooked. She instantly fell in love with the music and knew this is what she was looking for.
