Meet Dr. Marissa Hanna
Dr. Marissa has called the Upstate of South Carolina home for more than twelve years, though she originally grew up in Upstate New York. Her path to chiropractic has always been guided by curiosity about the human body and a deep respect for the body’s ability to adapt and heal when given the right support.
Before beginning her chiropractic career, Dr. Marissa spent two years owning and operating a restaurant. That experience shaped the way she approaches patient care today—with an understanding that people need healthcare that fits into their lives, not something that adds more stress to it.
After completing chiropractic school, she spent several years working in a thriving pediatric and prenatal chiropractic office, where she developed a deep passion for supporting mothers, babies, and growing families. During that time she saw how much mothers carry—physically, emotionally, and mentally—and how powerful it can be when families receive the right support during seasons of transition.
She is Webster Certified and has trained in several gentle chiropractic techniques that focus on supporting the nervous system and helping the body adapt more efficiently to stress. She is constantly pursuing additional training and coursework to deepen her knowledge and improve the care experience for her patients.
Dr. Marissa approaches every family she works with with deep respect for the responsibility of caring for children and supporting parents. Her goal is to create a space where families feel heard, supported, and cared for during some of the most important seasons of their lives.
Outside of practice, she enjoys traveling, going to concerts, camping, hiking, and spending time outdoors with her dogs.
Life is made up of thresholds—moments where we step from one stage of life into another.
Becoming a parent.
Welcoming a new baby.
Watching your child grow and develop.
Learning to carry the responsibilities of caring for others while still caring for yourself.
At Threshold Chiropractic, I believe these transitions deserve support.
The nervous system plays a central role in how the body adapts to the physical and emotional demands of life. When the nervous system becomes overwhelmed by stress, the body can struggle to regulate, heal, and function optimally.
Through gentle, nervous-system focused chiropractic care, we work to restore balance within the body by reducing stress patterns within the spine and nervous system.
By supporting the nervous system, we help individuals and families build the capacity to move through life’s transitions with greater ease.
Because health is not static—it grows and evolves as we do.
And every stage of life offers a new threshold to cross.
Why Threshold
My approach is rooted in a subluxation-based model of care — adjustments are aimed at correcting the underlying misalignments and restrictions in the spine, and nervous system regulation follows as the natural result of that correction. I hold a strong belief in the body's innate ability to heal and function well when it's free of interference, and that philosophy shapes how I care for expecting mothers, newborns, and children alike.
Within that model, my approach is primarily tonal rather than structural. A structural approach tends to focus on correcting specific misalignments through more forceful, biomechanically driven adjustments — treating the spine somewhat like a structure to be realigned piece by piece. A tonal approach is different: it's centered on the overall tone and adaptability of the nervous system itself, using gentle, specific input to help the nervous system find its own balance and self-correct from there. Rather than forcing a bone into place, a tonal adjustment is about communicating with the nervous system in a way that restores its natural ability to regulate the whole body.
This distinction matters most for the families I work with. Pregnant bodies and newborn spines aren't built for forceful correction — they respond to precision and gentleness. A tonal approach honors that. It also reflects something I believe deeply: that the body isn't a machine to be fixed, but a system that knows how to heal when it's given the right support. My job isn't to force change — it's to remove interference and let the nervous system do what it already knows how to do.
I also bring a holistic, attachment-focused lens to this work. I know that the early months and years with a baby are about so much more than milestones — they're about connection, trust, and the foundation you're building as a family. My hope is that every visit supports that, not just physically, but as part of the bigger picture of how you're raising your child.
