🎓 PhD Biochemistry
🧪 25 years Clinical Research
📚 Archival Researcher – Netflix “Arnold” Series
🏆 Host, Mr America Competition

I aim to bring a completely new premium level of online coaching to my clients.

This means that I will respond to you ASAP (and always within 24 hours, guaranteed) about any questions you have throughout the process of your program.

My clients are encouraged to message me via email on demand; any time they have a question or want my opinion on any of their diet and training.

From sending me a video of your exercise form to critique, to sending me pictures of particular food labels to see if they contain any "devitalizing agents", you will always have access to me as your coach to guide you to your goals.

That is what being your coach means to me.
