The people behind your care
Care that stays connected to your story.
Owner & Lead Provider
Kristin Mrnustik
MSN, APRN, FNP-BC
Kristin's path into healthcare began with rigorous training at Texas A&M, laying the foundation for a career grounded in science and service. She went on to complete her Nurse Practitioner training at Vanderbilt University, sharpening the clinical expertise she now brings to Oak Wellness, her functional and integrative wellness practice in Argyle, Texas.
Beyond her medical career, Kristin is an avid endurance athlete with multiple Ironman triathlon finishes and a Boston Marathon qualifying time to her name. That firsthand experience in endurance sports has shaped her belief that true well-being requires a holistic approach, one that looks at the whole person rather than a single symptom or number.
Kristin is driven by a profound desire to see others thrive in every aspect of their lives, and she leads the Oak Wellness team with that same commitment every day.
Kristin also speaks with groups about the long view of wellness — the bigger picture, not just the symptoms.
