Cellular Harmony: Inside the Healing World of Jessica Jacobson and Immortelle Integrative Health 

Within the Four Seasons Hotel Los Angeles at Beverly Hills, a new kind of healing is taking place—one that’s rooted in science, elevated by spirit, and curated with intention. Jessica Jacobson, is a trailblazing adult gerontology nurse practitioner and functional medicine specialist whose approach to wellness is transforming lives from the inside out.

Jessica is not your traditional healthcare provider. At Immortelle Integrative Health, she and her team are redefining the patient experience by merging the latest in genetic science, quantum healing, and lifestyle medicine—all within an oasis of calm and luxury.

“We’re not just looking at symptoms,” Jessica explains, her voice soft yet resolute. “We’re looking at cellular injury—what’s really going on beneath the surface. Stress isn’t just a feeling. It’s a biological event. It’s imprinted into the cells.”

A Calling Discovered by Living It

Jessica didn’t set out to become a pioneer in functional medicine. In fact, she stumbled into it—not by accident, but by instinct.

“I’ve been studying this my whole life without knowing it,” she says with a knowing smile. “I grew up in a chaotic home, all women, very little emotional regulation. I started exploring how smells, silence, and food affected me. That was my first exposure to integrative medicine. It was a coping mechanism that turned into a calling.”

Her path took her through traditional nurse practitioner training, but it was her extracurricular curiosity—exploring energetic therapies, light and sound healing, and holistic nutrition—that brought her true fulfillment. “I wanted to know how we could support the body naturally. That’s what led me into functional and quantum medicine.”

Living the Lifestyle

Jessica doesn’t just practice this work—she lives it. Her home life mirrors her clinical philosophy: conscious, intentional, and deeply attuned.

“We don’t drink alcohol, we’re mindful of noise and frequencies, even how we structure our water,” she shares. “Everything we consume—food, sound, energy—is a choice. People say it sounds restrictive. I think it’s expansive.”

That level of awareness—down to the vibration of the tea she drinks—is what makes her approach so unique. “We’re not chasing quick fixes. We’re creating harmony in the body.”

Precision Meets Personalization

At Immortelle, the journey begins with an intricate understanding of the individual. Patients often arrive frustrated, having been told by traditional doctors that their lab results are “normal”—despite lingering symptoms of fatigue, bloating, or burnout.

“We dive deep,” says Jessica. “From genetic and neurotransmitter testing to analyzing micronutrients and amino acids. We even tailor light and frequency therapies based on the individual’s energy signature. It’s not a one-size-fits-all model. Even identical twins have different treatment plans.”

“Some people are ready to go all in: no alcohol, clean nutrition, mindful routines. Others just want relief for a presentation or trip,” she says. “There’s no judgment. We meet you where you are, and we tailor everything—from your supplements to your energy frequencies—based on your needs, your DNA, and your goals.”

Jessica’s approach is a mosaic of old and new—reflexology and acupuncture paired with cutting-edge frequency technology and detox protocols.

“Technology is only as good as the practitioner behind it,” she notes. “We’ve moved beyond red light therapy to more precise methods—adjusting hertz frequency to target specific outcomes. That’s the art of what we do.”

Healing in a Challenging Environment

Jessica has seen firsthand how external environments can create internal damage. “After the LA fires, we had a significant increase in cases of what I now call ‘cellular injury’—not just stress. These environmental toxins were disrupting people’s health on a deep level.”

“We immediately look at toxicology and environmental toxin levels—what you’re breathing in and how it’s impacting detox centers like the liver, lungs, skin, and kidneys. Then we focus on nutraceutical interventions, oxygenation, and air purification to remove oxidative damage and relieve symptoms.”

“Our interventions can be incredibly affordable. A high-quality air purifier can take an enormous load off your lungs. And there’s a company we love that has simplified supplement protocols—what used to be 14 pills is now down to two or three. It’s easy, affordable, and realistic.”

A Global Footprint from a Single Sanctuary

Although Immortelle is based in Los Angeles, its impact is global. Clients from around the world—often guests at the Four Seasons—find themselves drawn into Jessica’s sphere, often unexpectedly.

“They come for the spa, and next thing you know, we’re talking about their health. We test, consult, and then support them wherever they are via telehealth. You don’t need to live here to heal here.”

While many encourage them to expand internationally, Jessica prefers the intimacy of their singular curated space. “We love what we do. We want people to come to us because this space is sacred.”

Wellness as a Way of Being

Jessica’s passion is not just healing—but teaching. Her ultimate goal is empowerment.

“We don’t want patients to rely on us forever. We want them to live. To learn. To thrive. A few small, high-impact changes can transform their lives.”

And the response from the traditional medical world?

“Surprisingly open,” she says. “Energy is physics. It’s not mystical—it’s measurable. And when doctors understand that, they become allies in our work.”

From Biohacking to Bioharmony

While she attends cutting-edge wellness conferences around the country, Jessica is selective in what she adopts. “There’s a lot of noise out there. People are biohacking themselves into oblivion. What we’re after is bioharmony—bringing the body into balance.”

She avoids labels and rigid protocols. Her approach is more fluid—based on resonance, intuition, and data.

“Homeostasis is the goal. Harmony with self, surroundings, and the greater energetic field.”

A Sacred Role

Despite the science, despite the luxury, despite the innovation—at its core, Jessica’s work is profoundly human.

“This is sacred work. It’s humbling. You’re helping someone rewrite the trajectory of their life. Every day I show up with grace, knowing the weight of that responsibility—and the beauty of it.”

When most race toward the next breakthrough, Jessica Jacobson reminds us that true wellness begins with stillness, intention, and a deep respect for the body’s innate intelligence. At Immortelle, healing is not just a protocol—it’s an experience. A journey inward. A return to balance.
