About Katie Johnstone

After more than a decade behind the pharmacy counter, I kept seeing the same pattern: people picking up more and more prescriptions for conditions that were rooted in lifestyle, nutrition, and hormonal imbalance. The conventional care model was treating symptoms — but rarely asking why.That pattern, combined with my own personal wellness journey, sparked a mission.I\'m Dr. Katie Johnstone — Wellness Pharmacist, Certified Health Coach, personal trainer, and nutritionist based in Portland, Maine. I now practice at Coastal Pharmacy & Wellness, where I offer one-on-one integrative wellness consultations designed to get to the root of how you feel and build a plan that actually works for your body and your life.My approach combines the clinical rigor of a decade-plus in pharmacy — including extensive experience in compounding and bioidentical hormone therapy (BHRT) — with a food-first, whole-person philosophy rooted in functional nutrition and lifestyle medicine. I studied functional medicine and bring that lens to every client I work with.I specialize in working with women who feel like something is off but can\'t get a straight answer from conventional medicine. Women whose labs come back \"normal\" but who are exhausted, gaining weight, losing their sharpness, and don\'t recognize themselves anymore. Women in perimenopause and menopause who deserve more than a prescription and a pat on the back.What I offer is different. Your initial consult is 60 minutes. We look at your full picture — hormones, thyroid, gut, nutrition, sleep, stress, and lifestyle. We run labs that conventional providers often miss. We build a protocol around your body, not a textbook. And we follow up regularly to adjust as you respond.I believe that the best version of healthcare happens when clinical expertise meets genuine human connection — and that women in their 40s and beyond deserve a practitioner who takes their symptoms seriously and has the tools to actually help.If you\'re a healthcare provider looking to refer patients who need more comprehensive lifestyle and hormonal support, or a colleague interested in the intersection of pharmacy and integrative wellness, I\'d love to connect.
