A Litte About Me

At Oak & Stone Wellness & Med Spa, I’m Brandi Terra, NP, and my passion is helping our San Diego community feel confident, vibrant, and truly well—inside and out. With a long history in clinical practice, I bring a strong medical foundation and a detail-driven approach to everything we do, from advanced aesthetics to whole-body wellness. I take pride in delivering results that look natural, feel empowering, and support your long-term health.

My work is also deeply personal. I’ve walked through my own hormone journey with premature menopause, and I know firsthand how frustrating it can be to feel “off” and not like yourself. That experience shaped the heart of Oak & Stone: a place where women are heard, supported, and given real answers—especially when it comes to hormones, energy, mood, weight changes, and overall wellness.

Our space is warm, calming, and intentionally designed with you in mind. When you share your story with me, I want you to feel at home—because this isn’t just about treatments, it’s about building a relationship and creating a plan that fits your life. Whether you’re here for hormone optimization, confidence-boosting aesthetic treatments, or both, my goal is simple: help you feel like the best version of yourself—supported, educated, and beautifully cared for every step of the way.
