Russ Ferrante, Anvil Health
Why I put my name on this
I'm Russ Ferrante. I'm 51, I live at 8,000 feet, and I'm in the best health of my life. I hunt, I fish, I'm on the mountain most days. I stay active so that I can stay active, and that only works if the machine underneath you is running right.
Anvil Health is how I point people to the team that helps me keep it running. Drs. Mark & Michele Sherwood at Functional Medical Institute build your plan from comprehensive blood work instead of guesswork: bioidentical hormones, third-party tested peptides, and someone who actually sits down and explains what your numbers mean.
An anvil doesn't wear out. Built right, it outlasts everything you put on it. That's what I want for your health.
