At The Mission Within, we are dedicated to not only creating a future free of veteran suicide, but a better world in which our heroes and their families find purpose, healing and growth through community.

The Mission Within offers:

  • Transformational psychedelic medicine retreat options.
  • Personalized psychedelic coaching sessions.
  • Expertly trained therapists and support staff that specialize in trauma.
  • Ongoing opportunities to connect with others on the healing path.
  • Unique opportunities for education and training in the psychedelic-assisted therapy space.

Since 2017, we have successfully provided treatment for PTSD and mTBI to hundreds of special operations veterans and their spouses. Many of which present with complex cases of mTBI, PTSD, depression & anxiety. Both participants and their therapists report significant improvement in their condition, with as many as 80% no longer meeting the diagnostic criteria for PTSD.

In addition to providing high-quality psychedelic medicine retreats, we are also actively engaged in changing the veteran narrative around psychedelic treatment. In an effort to make these powerful healing modalities more accessible to veterans, so that they can achieve the peace and healing that they deserve, we are actively engaged in innovative, cutting-edge clinical research. We’ve developed strategic partnerships with thought leaders and scientists from across the country with the shared goal of healing our veterans and their families. We won’t stop until Ibogaine, 5-MeO-DMT and Psilocybin are tools that are readily available to front-line providers entrenched in the veteran mental health crisis.

What Makes Our Approach Unique:

There is often so much shame in the participants coming to the program – these are alpha men and women who were programmed to carry the world’s weight on their shoulders. For them to admit there are mental health issues or challenges is difficult. That so many of our staff, therapists, and coaches are fellow veterans who have gone through the program themselves makes a vital difference. You are not alone, and with The Mission Within, you can be sure you are with your brothers and sisters on your healing journey.

Our goal is to create a better world in which veterans and their family members find healing, growth, and purpose through community. These psychedelic medicines have been healing communities across the globe for thousands of years. We are dedicated to bringing these powerful healing catalysts to as many veterans, spouses, and adult children as possible. Together, we will create a more beautiful world.

We understand that to create this world, we need to do more than deliver transformational psychedelic medicine retreats. So we are partnering with academic universities, scientists, and medical professionals to bring scientific rigor into this sacred space. Together, we will breathe life into a new medical paradigm. One in which our veterans and their families have timely access to psychedelic medicines and psychedelic-assisted therapies.


I’m sure everyone says this, but I think the people Dr. Martín Polanco has pulled together at The Mission Within are the most amazing people who could be in a program like this. Even the people preparing the food, the nurses and cardiologists, are just a fantastic crew. They prep you and keep in touch with you - they do an amazing job keeping in touch with you - it’s an amazing program.

Enrollment Guide

Erland was born and raised in Santa Barbara, California. At 18, he joined the Army and deployed for the invasion of Iraq as a young infantryman. Following that tour, he attended the Special Forces Assessment and Selection, and was selected for training as a SF Medic.

He was just struggling. Then he was introduced to Dr Polanco and attended an Ibogaine and 5-MEO-DMT retreat in Mexico. That weekend was the start of an upswing in his life. He has since completed a chemistry degree from UC Santa Barbara, has found work within the special operations community he finds very satisfying, he is much better with personal relationships, and just wakes up happy every day.
