DESCRIPTION OF SERVICES

  • There will be two medicine journeys administered during this one day retreat. The first one utilizing ketamine lozenges for a deepening into your Spirit nature. The second medicine journey will be with intramuscular ketamine, administered by Dr. Teismann and monitored throughout the journey.

  • Dr. Teismann and Tiffany Allen will guide you into a deep meditation to bring you to a centered and grounded place before entering into medicine space.

  • Yin Yoga is a modern yoga practice that is focused on going deep within oneself to bring healing both internally and also to the fascia, connective tissues and ligaments. This form of yoga involves holding postures for an extended period of 3-4 minutes while in a meditative state to bring you into deep connection with yourself.

  • Utilizing crystal bowls, chimes, bells, drums and other natural instruments, Tiffany will guide you on a musical journey to bring full relaxation and awareness to your entire body.

  • While this practice is much about connecting with your internal world, journaling assists you in writing down for yourself what matters most for the medicine journey and also to record any insights that you had after your journey.

  • The Om Kara is one of the most widely used mantras and one of the most powerful. Mantra means “Mind Protection”, so prior to going into the medicine journeys, we will collectively clear and purify the mind, while protecting it with this beautiful mantra.

  • Using a shamanic medicine drum, we will connect deeper with ourselves and each other through rhythmic sound. You will feel the ancient medicine during this profound time with your drum. We recommend that you bring your own drum, but if you don’t have one we have ones for use here at the Center.

  • During your medicine journey, you will receive profound insights that you come to feel as a “Knowing”. However, once we re-enter our regular life and our typical brain wave state, those Knowings can be forgotten before they are fully integrated into your life’s practices.

    For this reason, we will follow up the retreat with a one-hour Integration call where Tiffany will go over your insights and awarenesses from the journey, and guide you on how best to work them into your practical every day life.

    Additional Integration sessions are available at an addiitonal fee.

TESTIMONIALS

  • My three sessions to date have been nothing short of transformational. The conversations and connections that precede the medicine portion of the sessions paved the way for a life-changing experience that I would strongly recommend to anyone, if not everyone on the planet.

    Scott K, San Diego

  • I've done two sessions at Tree of Life to date—one on my own, and one with my partner. Both were profound experiences that will be with me for many years to come. There is still much work to be done individually, but these sessions helped me see a door that I hadn't realized was there, or perhaps had forgotten. Nathan and Tiffany both exude love and compassion, and are driven by a genuine desire to help other humans realize their own innate capacities and truths. This is a process we ultimately work through on our own, but I feel it has really helped to have the direction of an experienced and compassionate guide.

  • Nathan and Tiffany are grounded practitioners who are committed to creating a wellness space that honors the whole person. I will definitely be back for more of their offerings!

    Nicole S., San Francisco, CA

  • I cannot recommend Dr. Teismann and ketamine-assisted therapy enough to anyone working with mental health issues from childhood, or even if you're just stuck or going through a life challenge. I have been in therapy for over 35 years, and this work was the stepping stone into my deepest healing work on myself ever. If I had to choose one mode of healing for the rest of my life, it would be this one. And to have a medical professional, who is so deeply gifted in energetic and spiritual awareness is the most profound way to heal. Do yourself a favor and give yourself this gift.
