Our Approach to Stress & Mood Support


We begin with a comprehensive, root-cause–informed conversation focused on how stress shows up in your daily life. This may include exploring emotional patterns, stress responses, sleep quality, energy levels, and how lifestyle factors influence mood and resilience. We focus on understanding patterns and triggers that may be contributing to how you’re feeling.

1. Assess the Root-Cause


2. Support the Body’s Natural Balance

Our approach focuses on supporting the body’s innate ability to adapt and regulate. Instead of targeting symptoms directly, we emphasize foundational lifestyle and nutrition guidance designed to reduce unnecessary stress on the system and support overall balance. Recommendations may include guidance around food choices, daily rhythms, stress support, and the thoughtful use of supplements, herbal remedies, and homeopathic remedies when appropriate.


3. Build Strong, Sustainable Foundations

Many health concerns are interconnected, which is why we prioritize foundational habits that support the whole body. This phase focuses on consistency and sustainability, helping you implement realistic changes that can be maintained long-term.
Education plays a central role, empowering you with a deeper understanding of your body and how everyday choices influence overall well-being.


4. Reclaim Confidence in your Health

Our goal is not short-term symptom management, but long-term confidence and autonomy in your health. Through ongoing education and support, we help you build skills and awareness that apply across changing health goals and life stages.
This approach allows you to feel informed, supported, and capable of caring for your body over time—no matter the condition or focus area.

  • “Absolutely love Dr. Marissa! She has explained so much to me on one visit than all my doctors combined in several years! She was able to tell me things from reading my bloodwork that my doctors did not even pick up. Honestly amazing! She is so sweet, really listens and like I said really explains things! I highly recommend her!"

  • "Dr. (Zach) Main is the best!! He's not only a chiropractor but a true rehab specialist. He’s been so amazing to work with as a runner after an ankle sprain and heel pain. Dr. Main is patient, kind and explains everything along the way!"

  • “If you are looking for a doctor who is compassionate, present, and truly invested in your well-being, Dr. Marissa is an incredible choice. She desires to treat the whole person, not just a list of symptoms and it is why my experience with her set the standard for what health care should look like.”

  • "I cannot recommend Dr. (Zach) Main enough for movement and rehab needs! Knowledgeable and attentive, friendly and accommodating. I've definitely had significant improvement with my pain management under his care, as well as guidance on maintaining joint health through movement and exercise. The addition of dry needling to my treatment has also made a huge difference. So thankful!"
