My experience with Bella was top tier - she knows more about SIBO than probably anyone else who actually sees clients. I tried many doctors and clinics before I found her clinic and the difference was night and day. Not just with SIBO but with the many connected gut and health issues I had. I got my lift back and would absolutely recommend her to anyone in need of help.
I had to go outside of the general healthcare model when doctors were unable to diagnose or provide treatment for my GI and systemic issues. I decided to go with the Bella Lindemann Clinic because I had read their research on IMO and considered their messaging to be scientifically sound and thoughtfully crafted. When I was paired with Melanie as my practitioner, I couldn’t have been more impressed with her thorough, academic, and extremely caring treatment of my case. The only reason I do not give my experience a 5-star review is because of the cost. However, I was ready to pay the price for a renowned clinic because no other provider in my 5 year journey was able to give me what I needed to recover.
I’m deeply grateful for the work I’ve done with Christina and can’t recommend her highly enough.
We’ve worked together since late 2024 through multiple layers of healing: dysbiosis, candida, hormonal suppression, pathogens, nervous system dysregulation and SIBO. What sets Christina apart is her intelligent sequencing. She never rushed to kill off SIBO and hope for the best (which other practitioners have done and which led to relapse), but instead she understood that in my case SIBO was a nervous system issue first and a gut issue second. She recommended tools for nervous-system regulation alongside gut-focused protocols, which made all the difference.
Thanks to her guidance, my MMC has come back online, my gut health has improved immensely and I'm now free from SIBO. If you’re looking for a practitioner who combines clinical precision with true systems-level understanding, Christina is outstanding.
