Meet our Instructors
Emily Sampley
Founder & Instructor
Emily's passion for fitness came from watching her parents' active lifestyle and realizing that fitness is not just a hobby, it's a lifelong commitment. Emily has been teaching group fitness classes since 2019 and is certified in group fitness and yoga sculpt; and her background is in outdoor education. Emily's most important goal at Medley on Main is to make sure everyone feels welcome. It takes courage to show up for a fitness class, and she knows this. Emily is always working to further her fitness knowledge by attending other fitness classes outside of her own studio, and listening to podcasts, and reading books about fitness. "I could not do any of this without the support of my beautiful children and husband who does all the hard work behind the scenes."
