About
Most fitness coaches will hand you a meal plan and a workout program and call it coaching. I do something different.
I'm an NASM certified personal trainer and nutrition coach, and my entire approach is built around one thing — giving you the actual evidence behind what works, not the trends, the supplements, or the quick fixes that the fitness industry profits from.
If you've tried diets that worked until they didn't, followed programs that made no sense, or gotten conflicting advice from every direction and have no idea what to believe anymore — that's exactly who I work with.
What I do: personalized nutrition coaching and strength training programs built around your actual life. Your schedule, your food preferences, your goals. Not a template with your name on it.
What I don't do: sell you supplements, put you on a 1,200 calorie diet, or promise a transformation in 30 days.
What you get: a coach who explains the reasoning behind everything, adjusts the plan when life gets in the way, and holds you accountable without shaming you for being human.
If you want to lose fat, build muscle, and finally understand why something is working so you can keep it working long after coaching ends — I'd love to talk.

I was initially skeptical about hiring a fitness coach online, but Josh was a delight to work with! He was great in making sure my concerns were heard and he helped me lose the 15 pounds that I had been trying to lose for 6 months before working with him.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
I offer three coaching options depending on your goals and what level of support makes sense for your situation.
Comprehensive coaching — personalized nutrition and training program, weekly check-ins, and direct access to me — is $250 per month.
Nutrition coaching only is $150 per month.
Personal training programming only is $150 per month.
All coaching is month to month with no long-term contracts. I occasionally offer reduced rates for case study clients in exchange for permission to document and share their progress. If budget is a concern, reach out and we can talk through what makes sense.
What is your typical process for working with a new customer?
It starts with a short application so I can understand your goals, your current situation, and what you've already tried. From there we get on a 15 to 20 minute call — no pitch, just a real conversation to make sure we're a good fit and I can actually help you.
If we move forward, I build your program around your specific schedule, food preferences, training access, and experience level. We do weekly check-ins so I can see what's working, what isn't, and adjust accordingly. You have direct access to me between check-ins for questions, form feedback, or anything that comes up.
The goal is never just to give you a plan. It's to help you understand why the plan works so you can keep the results long after coaching ends.
What education and/or training do you have that relates to your work?
I'm a certified personal trainer and certified nutrition coach through NASM — the National Academy of Sports Medicine. My approach is evidence-based, meaning everything I recommend is grounded in peer-reviewed research rather than fitness trends or personal opinion.
I've been training clients for the last 3 years and have spent years studying the gap between what the fitness industry tells people and what the science actually supports. That gap is exactly what I built my coaching practice around.
