Our approach

What Makes Oneness Different?

No two people heal the same way. Your preparation, your session, and the integration that follows are shaped around your history and your goals, with Oxana beside you the whole way.

One-on-One Relationship-Based Healing

The most meaningful healing happens within a strong therapeutic relationship built on trust, safety, and individualized support. Psychedelic work is deeply personal and intimate; many benefit from the depth, privacy, and attention of one-on-one work. From intake and preparation through the session and ongoing integration, you're supported by the same therapist throughout — continuity that allows a deeper understanding of your story and process.

Root-Cause Healing

Many modern approaches focus on managing symptoms. We look deeper — the underlying causes and patterns. We believe in the body’s natural ability to heal when the right environment is created: nervous-system regulation, trauma-informed approaches, lifestyle practices, and emotional awareness.

Personalized Care

No one-size-fits-all. Every person has a unique story, nervous system, challenges, and goals. Preparation, therapeutic approach, psychedelic protocol, and integration are aligned specifically with you.

One guide, the whole way.

I bring together four fields that rarely meet: law, addiction treatment, wellness, and psychedelic-assisted healing. I built Oneness on one idea, that healing is personal and needs a setting shaped around the individual.

Stories

In their own words

The ceremony she guided was one of the most beautiful and heart-opening experiences of my life. Her calm, grounded energy allowed me to truly let go and trust the process. … I feel like myself again — only stronger.
CADepression
  • I reached a point in my life where I felt there was no effective way to get help for my depression outside of pharmaceutical drugs. … She made the entire process incredible, and I never felt alone on my journey.

    PSSuicidal
  • I have had a truly life altering experience under Oxana's guidance. I have learned the psychedelic journey itself is just the beginning of the change. It takes strong consistent integration to establish our own individual state of healing.

    JPPersonal growth
  • From the very beginning of my session experience to the very end, I felt completely safe and supported by you, Oxana. … I had no fear going into this experience—your expertise and calm presence gave me total confidence that I was in the best possible hands.

    MPPTSD
  • I was initially hesitant about microdosing, worried it might lead to dependency, but after committing to a 60-day experience with Oxana, I noticed profound changes. … Most importantly, I never felt dependent — I learned to intuitively pace my doses.

    ASMicrodosing
  • At 56, I had been struggling with chronic pain for years due to arthritis and inflammation. Since starting the microdosing journey, my pain has almost completely disappeared. I'm finally able to sleep through the night, move my body with ease, and even started exercising again — something I never thought I'd enjoy doing.

    LKChronic pain
  • After losing my wife, I sank into deep grief and depression. I tried therapy, medication, and countless ways to cope, but nothing truly helped me move forward. … Over time, the heaviness began to lift — I started to smile again, to feel calm, and even moments of real happiness.

    CBGrief & loss
  • I'm a veteran who has carried severe trauma for more than forty years — from childhood and from service. … In just one six-hour session, I released emotional weight I had carried my entire life. My relationship with alcohol changed, my sleep improved, and the anxiety and trauma symptoms that once controlled me eased dramatically.
