Greetings! My name is Carlie. +
I am a neurology activist, researcher, and entrepreneur building
Possibilities.

The mission of Possibilities is to advance understanding and access to neuroplasticity therapies for people with brain injuries. And to provide these therapies in environments that are conducive to healing – in nature, within community, and alongside somatic practices that align the mind and body. More coming soon.
My email is carlie@brainpossibilities.org.
I'm open for brain injury research collaboration, industry opinion, coaching, or a good NYC bagel.
Be in touch! I am obsessed with this stuff.
How I got here +
Growing up in Wisconsin, my home was chaotic so I oriented myself around achievements. I won cattle shows and dance competitions. I went to Wharton to study finance while working in Wall Street and software startups.
My ego was then destroyed when I sustained a severe traumatic brain injury in 2019, hit by a car as a pedestrian. Maybe 10-15% of my brain died. After just four months of rehab, I was discharged for "plateauing" and told to accept how my life would be different now (now that I was disabled, for good). I was at the functional level of a kindergartener and that was considered good enough. I had no idea who I was or what to do. The resulting standard of care was symptom-whacking medications that I would be on likely for the rest of my life. Absolute despair and hopelessness.
Gratefully, I found my way to therapies that enhanced my brain's neuroplasticity for my functional deficits, symptoms, and trauma. These included somatic exercises, psychedelics, and neuromodulation technologies. I found them in alternative and international clinics, mostly. And I no longer live with chronic symptoms of photosensitivity, vertigo, migraine, fatigue, or insomnia. I humbly admit that my mental health is an ongoing and evolving project, and I'm grateful for my tools. I'm also graetful to say I take no medications! The brain and can indeed heal. The lost soul can be uncovered.
I couldn't forget that many of my allopathic clinicians along the way claimed ignorance to the idea of healing - it was either an unknown void, impossible, or worst of all: passive.
Bewildered that hopelessness and symptom-whacking was the state of Medicine, I went back to school for pre-medicine coursework at the University of Wisconsin. I was preparing to become a neurologist who could redefine what was possible after brain trauma. With the Vemuganti Lab of Neurosurgery, we researched mouse models of brain injury and neurodegeneration. With Parkython, Concussion & CTE Foundation, & LoveYourBrain Foundation, I began advocacy and peer mentoring.
Instead of medical school, I'm building in the neurology neuroplasticity revolution. My organization is called Possibilities, and it is a nature and community based neuroplasticity center for people with brain injuries. I'm seeking to learn from and collaborate with neurologists, neuropsychiatrists, neuroscientists, clinic operators, psychelelic-assisted and EMDR-trained therapists, and other natural practitioners who are on the same endeavor.
We can all be excited about this research on emerging therapies +
Evidence on ibogaine

It's important to find a clinic that has safe medical practices and a brain injury-accessible enivronment and programming. The risk of attending an ibogaine clinic that's not disability-conscious is
medical traumatization which...we'd like to avoid right?
