I'm so excited about learning about Mountainside fitness and all they have to offer from Chantel Griswold. She took her time explaining what they had to offer and was happy to help. I needed to reschedule my trainer appointment and no problem, she jumped right in and helped. People like Chantel make this a friendly atmosphere and make everyone feel welcome!
