My ideal client is a woman 35+ dealing with perimenopause or menopause. She’s frustrated by stubborn belly fat, low energy, poor sleep, mood swings, bloating, thinning hair, and skin issues (despite doing “everything right"). She wants real, long-term solutions. Her goal is to feel like herself again (or a better version of herself): leaner, energized, clear-headed, with clearer skin and fuller hair. She’s seeking expert guidance to optimize her metabolism, balance hormones, improve gut health, and get lasting results.

I help women restore energy, lose weight, manage PCOS, blood sugar and optimize fertility through a functional nutrition lens.
You’re probably sick of the bandaid approach by now and want to get to the root-cause of your symptoms like weight gain, blood sugar concerns, PCOS, irregular cycles, or fertility struggles. You’re also probably tired of feeling like your healthcare providers barely listen in the few minutes you get with them (and send you off with a prescription). It’s frustrating to feel like nobody hears your struggle or can provide the support you know deserve. You can be helped and you can feel better - medication and being stuck in this cycle are not your only options! The good news? You’re already on the right track by seeking my help.
