What I do
Hormones touch everythingfrom energy and sleep to mood, metabolism, cognition, and sexual health. I evaluate and optimize the key players (such as estrogen, progesterone, testosterone, thyroid, and DHEA) and add practical lifestyle strategies plus evidence-guided therapies to help you feel steady, strong, and clear-headed. When appropriate, we may support your plan with peptide therapy, targeted supplements, and treatments that promote healthier hair and skin. I also offer specialized care for women’s sexual health.
And yes, men’s hormones are just as important fewer dials to turn than women’s, but each one matters and deserves precision.
How we’ll work together
- Listen & assess: A detailed history and targeted labs to identify what’s driving your symptoms.
- Personalize: A clear, practical plan hormone optimization (when appropriate), nutrition, movement, sleep, and recovery.
- Optimize: Careful titration and regular check-ins to keep you progressing without overwhelm.
- Maintain: Education and support so results last in real life.

Life outside the clinic
I’m happily outnumbered at home with a big, blended family eight kids, one daughter-in-law, and a loving golden retriever, which all keeps life grounded and lively. They remind me daily that health should give you more time for what you love.
Ready when you are
If you’ve been told your labs are “normal” but you don’t feel that way or you’re simply ready for care that listens and lasts I’m here for you.
