  • “I was a patient of Dr. Marissa for nearly two years, and she was my very first naturopathic doctor. From the beginning, working with Dr. Marissa transformed my life. She embodies compassion. She cared so deeply and genuinely about my medical concerns, and from day one treated me as though she truly knew me. Over time, our doctor-patient relationship grew into a space of deep trust and I felt safe bringing her everything including my frustrations, my fears, my health struggles. I felt this way because I knew that I would be met with honesty, warmth, and unwavering care and support. On a consistent basis, she went above and beyond to ensure that I felt comfortable, heard, and supported.”

  • “I was under the care of Dr. Marissa for about a year, and from the very beginning I felt completely comfortable with her. She was truly invested in helping me and always took the time to explain anything I needed more information on. Dr. Marissa genuinely listened to and understood my concerns, which is something that feels rare these days. I’m very grateful for the care she provided throughout my time as her patient. I highly recommend Dr. Marissa!"

  • "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!"
