Rooted in Science. Guided by Compassion. Built for You.
Cerulean Health & Wellness is a nurse practitioner-led telehealth practice in Los Angeles specializing in functional medicine for adults who are tired of being told "your labs are normal" when they know something is wrong. We help uncover the root causes of fatigue, gut issues, hormonal imbalances, and chronic stress — so you can finally feel like yourself again.
Our name, inspired by the peaceful cerulean sky, reflects our mission: to restore clarity, energy, and balance — body, mind, and spirit. We are proudly LGBTQIA+-affirming, and all people are welcome here.
Our Mission
To transform lives through personalized, root-cause-focused functional medicine — empowering clients across California to reclaim their energy, balance, and vitality from the inside out.
At Cerulean, we believe that true healing cannot happen in a 7-minute appointment. It requires time, deep listening, and a genuine understanding of each person's unique biology, lifestyle, and goals. That's why we built a direct-pay telehealth practice that puts the client — not the insurance company — at the center of every decision.
David Boyd, DNP, FNP-BC, FMACP
David Boyd is a board-certified Family Nurse Practitioner and Functional Medicine Academy Certified Practitioner with over 20 years of diverse experience in healthcare. His background spans emergency medicine, trauma, ICU, nursing leadership, primary care, and now functional and integrative medicine.
After two decades at the front lines of traditional medicine — including years in emergency rooms and critical care units — David witnessed firsthand the limitations of symptom-based treatment. Too often, patients were prescribed medication after medication without anyone asking the most important question: why?
That experience led David to pursue functional medicine and ultimately to found Cerulean Health & Wellness — a telehealth practice dedicated to uncovering and treating the root drivers of fatigue, gut dysfunction, hormonal imbalance, weight challenges, and chronic stress.
As a member of the LGBTQIA+ community himself, David understands the unique health challenges that queer, transgender, and gender-diverse individuals face — from minority stress and its physiological effects to the difficulty of finding a provider who truly listens without judgment. Cerulean was built to be the practice David wished existed: affirming, thorough, and genuinely invested in each client's wellbeing.
David holds a Doctor of Nursing Practice (DNP) degree and is board-certified as a Family Nurse Practitioner (FNP-BC). He is a certified Functional Medicine Academy Practitioner (FMACP) and currently practices telehealth functional medicine serving clients throughout California from his base in Los Angeles.
