What is The Mend Wellness?
The Mend Wellness is a boutique Functional Medicine Practice serving patients throughout New York and Connecticut. Founded by Kristin Brien, FNP-BC, FMCP-M™—a board-certified Functional Medicine Family Nurse Practitioner trained at NYU and Mount Sinai—The Mend Wellness was created for people who are ready to look beyond symptom management and explore the deeper factors affecting their health.
Health is more than the absence of disease. It is having the energy to engage with your life, a nervous system that feels safe enough to rest and repair, and space for joy, connection, meaning, and purpose. Physical, mental, emotional, and energetic well-being are deeply interconnected—and lasting healing requires caring for the whole person.
Many chronic patterns — hormonal shifts, stubborn changes in weight and metabolism, disrupted sleep, anxiety, fatigue that doesn't resolve with rest — are shaped by modifiable factors like nutrition, movement, stress, and environmental exposures. But health is never defined by lifestyle alone. Genetics, life experience, relationships, and your body's own history all shape what's happening beneath the surface, which is why hormonal patterns like perimenopause, menopause, andropause, and low testosterone, along with painful periods and PMDD — and metabolic ones like PCOS (now also recognized as PMOS), insulin resistance, type 2 diabetes, and thyroid imbalance — deserve real investigation rather than a standard checklist.
At The Mend Wellness, we combine functional medicine, comprehensive laboratory testing, and whole-person care to investigate the underlying contributors that may be keeping you from feeling your best. Together, we create a personalized, evidence-informed plan designed to address the root cause of your symptoms based on your health history and goals—so you can move beyond simply functioning and feel fully connected to yourself and your life.

Functional Medicine Services
Your health story deserves more than a quick visit or a one-size-fits-all fix. During your comprehensive consultation, we explore your symptoms, history, lifestyle, environment, and goals to understand what's really driving your health — then build a personalized plan with nutrition, lifestyle strategies, supplements, medication, and nervous-system support as needed, guided by testing when appropriate.
Because even the best recommendations only work when they fit your life, we help you turn them into sustainable daily practices. Personalized coaching and compassionate accountability help you adapt when life becomes stressful, routines shift, or circumstances don't go according to plan — without losing sight of your health or feeling as though you have to start over.

Nervous System Reset
Healing that reaches beyond the surface. Chronic stress can leave your body feeling stuck in survival mode — wired, exhausted, overwhelmed, or unable to fully rest. Through breathwork, guided meditation, EFT tapping, and other personalized regulation practices, we help you create a greater sense of calm, safety, and connection within your body.
Distance Reiki may also be woven in as a gentle, non-invasive complementary energy practice designed to support relaxation, restore a sense of balance, and create space for deeper rest. Together, these practices offer meaningful support for your physical, mental, emotional, and energetic well-being — helping you reconnect with yourself, your joy, and the life you want to create.
