Patient Testimonials
“I can’t say enough how grateful I am to have found Fitzgerald Health. I was struggling with symptoms and no real diagnosis, and she took the time to understand me (far more time than any doctor I’ve ever had), ordered blood and other tests, and we came up with a holistic health plan. I went from being preoccupied with my symptoms to having a partner who genuinely cares about me as a person, is an expert in the latest developments, treats the whole person, and is also reasonably priced. I’d give ten stars if I could.”
"Kirsten was extremely knowledgeable, and her manner was warm, welcoming, and inviting. She put my son at ease."
"Dr. FitzGerald is an incredible APRN, my best care giver ever! She has supported me in getting my thyroid hormones back on track and I am feeling much better!"
"Dr FitzGerald was beyond helpful. She knew exactly where to touch and she explained where my pain was coming from. After months of this I totally trust and feel like I am in the right place."
Functional Medicine in Ridgefield, Connecticut
Traditional medicine provides essential pharmaceutical-based medical care, but it often focuses on managing symptoms rather than addressing the underlying cause of illness. Functional Medicine takes a more comprehensive approach by identifying the root causes of disease through detailed health histories, in-depth consultations, and specialized laboratory testing. This approach allows practitioners to develop targeted, natural, and lifestyle-based treatment strategies that support the body’s ability to heal.
Dr. FitzGerald combines Functional Medicine with conventional medical care to deliver truly personalized and holistic treatment. As a fully licensed clinician, she integrates modern medical science with lifestyle, environmental, and nutritional therapies to support long-term health and disease prevention. This integrative medicine approach helps patients achieve lasting wellness by treating the whole person—not just the symptoms.
What to Expect at Your First Visit
Your initial consultation typically lasts up to two hours, allowing time for meaningful discussion, comprehensive evaluation, and collaborative goal setting. During this visit, Dr. FitzGerald carefully reviews your medical history, past surgeries, current symptoms, and any recent laboratory or imaging results, followed by a physical exam.
Based on this evaluation, a personalized treatment plan is created, which may include:
Routine and specialty laboratory testing
Nutrition and dietary guidance
Body composition analysis
Practitioner-grade nutritional supplements
Personalized exercise and lifestyle recommendations
Stress reduction and mindfulness practices
Homeopathic or natural therapies
Guided meditation or EFT (Emotional Freedom Technique)
When appropriate, pharmaceutical treatment or referrals to specialists and physical therapy
A Root-Cause Approach to Long-Term Wellness
By addressing the underlying drivers of illness, functional medicine can help patients restore balance, improve energy, reduce inflammation, and optimize long-term health.
Dr. FitzGerald’s integrative approach supports patients across Connecticut and the surrounding region in achieving sustainable wellness through preventative care, lifestyle medicine, and personalized treatment plans.
The goal is simple: help patients heal, prevent disease, and experience lasting health and wellbeing.
