Precision Medicine. Personal Care.

Michael Santiago, MSN, AGACNP-BC

At RevitaLine, your care is guided by a highly trained Nurse Practitioner with nearly a decade of experience in critical care and cardiovascular medicine. With an extensive background managing complex cardiac and medically fragile patients, your provider brings a deep understanding of physiology, hormone balance, metabolic health, and preventative medicine to every treatment plan.

Years spent in high-acuity hospital settings have shaped a meticulous, safety-first approach grounded in evidence-based medicine. This experience translates into thoughtful diagnostics, personalized treatment strategies, and careful monitoring designed to optimize long-term health — not just deliver short-term results.

Beyond the clinical setting, a lifelong passion for health, fitness, and performance fuels a holistic philosophy of care. RevitaLine blends medical precision with wellness optimization, empowering patients to improve vitality, restore confidence, enhance appearance, and perform at their highest level.

This unique combination of critical care expertise and wellness innovation ensures that every client receives care that is comprehensive, strategic, and tailored to support living life at its fullest potential.

Tintu Chiramel, DO

From a young age, Dr. Chiramel was drawn to two pursuits — medicine and art — and her work in aesthetics is where they finally meet. After more than a decade practicing internal medicine, she found a path where clinical precision and artistry reinforce one another. With formal training as a makeup artist alongside advanced expertise in injectables, she brings an artist’s eye and a physician’s judgment to every treatment, enhancing each client’s natural features with balance and restraint rather than reinvention.

Her medical background grounds the aesthetic work in safety and sound clinical reasoning, while her love of the arts shapes how she approaches the craft — reading proportion, symmetry, and the small details that make a result look natural rather than done. Through her practice, Glow Medical Aesthetics, she partners with RevitaLine Health to offer aesthetic treatments that help clients look and feel their best with confidence, elegance, and care.

Dr. Chiramel also serves as collaborating physician for Santiago Acute Care NP Services PLLC (RevitaLine Health), supporting the practice with physician collaboration.

Why We Built This.

RevitaLine was founded from nearly a decade of frontline experience in critical care and cardiovascular medicine. As a Registered Nurse and now Nurse Practitioner, I cared for patients facing advanced heart disease, metabolic disorders, and complex chronic illness — often at the most critical stages of their health journey.

While that work was deeply impactful, it revealed a powerful reality: by the time many individuals reached the ICU, their health had been declining silently for years. Hormonal imbalances, metabolic dysfunction, inflammation, poor recovery, and lifestyle stressors had compounded long before symptoms became severe.

RevitaLine was created to intervene earlier — to shift healthcare from crisis management to proactive optimization.

By combining advanced clinical training with evidence-based preventative strategies, we focus on hormone balance, metabolic health, targeted nutrition, performance optimization, and regenerative therapies designed to enhance vitality and reduce long-term disease risk. Our mission is not simply to treat symptoms, but to strategically support the systems of the body that drive energy, strength, confidence, and longevity.

At RevitaLine, prevention is powerful. Optimization is intentional. And living with strength is the standard.
