  • CRYSTAL! She's the best. So friendly, knows what she's doing and has kept all this afloat during a PANDEMIC!

  • Crystal is vibrant and wise! She has been able to meet me exactly where I am - physically and mentally. Her motivational style is very natural and she keeps it real. I highly recommend her training expertise. Crystal has taken extra precautions since COVID-19 and the studio has been great and comfortable to be in. I can't believe it took me so long to engage a personal trainer.
