What is his coaching style?
Calm, exacting, and personal. No yelling, no hype, no bootcamp theatrics. Jonathan builds your plan, writes your nutrition, watches every rep, and checks in with you between sessions. He is caring but stern: he will meet you exactly where you are, and he will not let you quietly disappear when motivation dips. That combination is why client retention here is measured in years, not billing cycles.
Why do women 30+ train with him?
Because he has spent two decades coaching women through the exact body changes most trainers ignore: postpartum recovery, perimenopause weight gain, and lately the muscle loss that comes with GLP-1 medications like Ozempic and Wegovy. The training and nutrition adjust to your hormones and your life instead of fighting them. See the transformations.
“I've worked with 5 personal trainers throughout my life, but Jonathan's the best. There is no one size fits all. He recognizes each client's goals and works with you accordingly.”
