In Denville, one wellness center stands out for a simple reason: it’s run with the heart of a family caring for its own.
In true like-mother, like-daughter fashion, the Natural Care Holistic Health Center in Denville offers holistic, hands-on services to promote natural healing and wellness. Meet owners Tiffany Cuello Siegel and her mother, Mariana Cuello.
As founders of the center, they combine naturopathic and functional medicine to support patients in achieving optimal, long-term health.
"At our practice, patients are treated like family, with thoughtful and compassionate care," Tiffany shared.
Both Tiffany and Mariana’s work is guided by the gut-brain connection and the body’s remarkable ability to heal itself.
Though they collaborate daily, they each bring their own specialty to the practice. Mariana is a naturopathic doctor, colon hydrotherapist, and licensed massage therapist, while Tiffany is a functional nurse practitioner and board-certified colon hydrotherapist.
So, how did this nurse practitioner, colon hydrotherapist, and first-time mom land in business with her own mother?
A Dominican Republic native, Mariana grew up with natural and organic remedies as a way of life. Passing those generational healing traditions to her daughter felt instinctive—and now Tiffany continues that legacy with her own patients.
The practice embraces a whole-body approach rather than addressing symptoms in isolation, with particular emphasis on gut health and overall wellness.
One service they specialize in is colon hydrotherapy (colonic), a safe and effective method of removing toxic waste from the colon without the use of drugs or laxatives.
The center’s philosophy is deeply restorative, centering on bringing the body back into balance. Personalization is also front and center, as each patient is individually assessed and receives a treatment plan tailored to their needs.
That personalization is often based on testing such as blood work, which can reveal imbalances in hormones, vitamins, minerals, and more.
An imbalance of nutrients or hormones can contribute to sluggishness or chronic fatigue, which is why a vitamin panel is often the next step—sometimes leading to a recommendation for IV vitamin therapy. Other instances may call for an immunity-boost infusion consisting of portioned-out ratios of Vitamin C and Zinc.
“It’s a personalized cocktail,” Tiffany explained.
The immune system and detoxification are central tenets that embody a more holistic approach.
In addition to colon hydrotherapy and IV infusions, the center also provides vitamin supplementation and non-GLP1 weight-loss injections.
“We want to empower you with health,” she said. “The body is a temple and you have to take care of it.”
Currently, the patient base at the Natural Care Holistic Health Center is nearly balanced, with a 60-to-40 ratio of women to men.
“Anyone who has a colon, we will treat,” Tiffany joked.
There is a clear commitment to meeting patients where they are and supporting lasting change.
“While holistic modalities produce results, lifestyle changes to accompany them are paramount,” she added.
This includes intentional shifts in diet, regular movement, and time outdoors.
“It’s really a contract in investing into yourself."
As a mother to an 8-month-old daughter, she stays just as active outside the office, also balancing her work as a nursing professor with family life and fitness.
At its core, Natural Care Holistic Health Center is built on a simple belief: caring for your body is one of the greatest acts of love you can offer yourself. Guided by that philosophy, Tiffany and Mariana help patients embrace wellness as an ongoing relationship—one strengthened through awareness, consistency, and genuine self-care.
They continue to carry forward a legacy of compassion, education, and generational wisdom, encouraging individuals to treat their body with the same tenderness they offer to those they love most.
Natural Care Holistic Health Center is located at 35 West Main Street in Denville.
