I became a CCFM patient about 2 years ago given unexplained chronic symptoms which can not be diagnosed and addressed by conventional medicine. After onboarding, I went through a lot of tests over the next few months to check abnormalities in GI, autoimmune, hormone, metabolism, mold and mycotoxins exposure. The test uncovered major issues such as gluten sensitivity, mold and mycotoxin burden. Tracey O’Shea, who has been my care provider in CCFM since onboarding, explained to me all the test results and discussed next steps and answered any questions I have at each video appointment, and wrote me detailed encounter history from the appointment and instructions to follow post each visit. The treatment plan is an holistic approach which includes adding supplements to address root cause of the issue, diet and life style change. The treatment requires dedication and discipline, but the result is definitely rewarding. I started to see subtle improvements in my energy level and my symptoms are becoming less and less noticeable over time. I have been with CCFM for almost 2 years now. The partnership with my care team is getting stronger over time. I truly appreciated the thoughtful care and support from my care team in CCFM who showed me there is a way to be healed from the chronic illness and to live a healthier life. I also gained valuable knowledge about nutrition and its connection to our body. I think joining CCFM’s patient program is one of the best decisions and investments I made for myself. The positive and sustainable results I see on myself is motivating and rewarding. Although there are still issues to be addressed, I am generally feeling better, and thinking more positive these days. CCFM, thanks for everything.

I came to CCFM after a two year journey with my internist and an integrative doctor (along with a lot deep diving on my own.) CCFM welcomed me with a smile and made me feel like I could breath. They analyzed all my previous tests and blood work. They listened to me and didn't put all my symptoms on the back burner. Best of all, they made sure I felt heard. I would say the word that describes my experience thus far is SUPPORT. Every month (if not more), I am communicating with someone on my health team and any question is only a message away. I look forward to the positive changes I see in my health as I continue working with CCFM.

I spent years bouncing between different doctors and practitioners. Traditional, natural, you name it. No one was able to figure out what was going on with me. I knew something was off but kept hitting dead ends. Working with CCFM was a total game changer. They actually listened, cared, and never tried to push a one-size-fits-all plan. It felt collaborative from the start. They were open to my input and we worked together to figure things out. They looked at everything—not just labs and supplements, but also my diet, lifestyle, mood, stress, and more. They ran the most in-depth testing I’ve ever had and uncovered things no other doctor ever did. Honestly, if I hadn’t found them, I don’t know where I’d be right now. I’m really grateful for their support and would recommend them to anyone who feels stuck or like they’ve been searching for answers.
