Mira is a California-licensed Family Nurse Practitioner specializing in functional and regenerative medicine. As the IV Nurse and Lab Manager at Solcere, she leads with clinical precision and a deep passion for whole-person healing. Having been trained directly by Dr. Sandison, her work centers around root-cause medicine, neuro-optimization, and restoring balance in the body at every stage of life, because brain health and vitality aren’t just for the young, they’re for the lifelong. Originally born in Queens, New York, and raised across continents, Mira’s global perspective is infused into her practice. She earned her BSN in the Philippines and completed her clinical training at Loma Linda University. After years of outpatient surgery, she felt called to dig deeper, beyond surface symptoms, to uncover the true drivers of illness.

Her approach is rooted in the belief that the body is intelligent and capable of profound healing when given the right support. She emphasizes personalized care plans that target inflammation, hormone balance, mitochondrial function, gut-brain connection, and neuro-regeneration, empowering patients to reclaim their vitality, clarity, and resilience. “When we stop chasing symptoms and start listening to the body’s signals, we discover the true art of healing.” – Mira As a dedicated member of the American Holistic Nurses Association, California Association for Nurse Practitioners, and the American Association of Nurse Practitioners, Mira is especially passionate about helping patients enhance cognitive performance, restore emotional balance, and prevent neurodegeneration through evidence-based, holistic care.
