About Sierra Botanica & Collaborative Medicine

What does Collaborative Medicine mean?

Collaborative is a departure from a hierarchy, where the patient is at the center and gets to decide who is at the table, and everyone at the table is allowed to bring the full glory of their particular toolbox to the table ultimately for the patient to decide what is best for their particular situation.  Not only is it effective, but it’s fun.

Collaborative is an invitation.  

Since healing always happens in community, we invite patients to be in connection and harmonious communion with their inner Divine Healing God(s), their inner microbial community, their external social community, and take an active role at the head of the table with their professional team of clinicians. 

We invite the patient to connect and collaborate as well as every other member of the team (Physicians, PCP’s, therapists, clergy, etc.) which may or may not be geographically located at our clinic. 

Just like with any successful musical collaboration, listening is a key part of the process and different viewpoints, backgrounds, instruments, and styles often produce beautiful results when there is symbiotic connection and open honest collaboration.
