Jon Dennis, Esq. is a lawyer and activist in the psychedelics ecosystem and a consultant at the firm, Psychedelics Now. He is the co-host of “Eyes on Oregon,” a podcast by Psychedelics Today exploring the latest developments in Oregon’s legal psilocybin landscape. He serves on the Executive Committee of the Oregon State Bar Practice Section on Cannabis and Psychedelics and is a co-chair of its Psychedelics Subcommittee. He is a member of the Psychedelics Bar Association and sits on its Religious Use Committee.

Jon is the chief architect of the proposed regulatory framework for protecting religious and spiritual communities who operate under Oregon’s new psilocybin program.

Jon has taken the North Star Ethics Pledge and is drawn to this work by the conviction that psychedelics possess the potential to accelerate our individual and collective shifts away from self-destructive paradigms.

Abby Volin is an employment attorney representing individuals in workplace discrimination, harassment, and retaliation matters, and advising employers on policies that uphold the civil rights of all people. She is also a mediator trained in the understanding-based model, which centers self-knowledge and mutual understanding as the foundation for resolving conflict and repairing relationships. 

Abby believes that psychedelic lawyering requires lawyers to do their own inner work, as legal expertise alone is insufficient without integrity, presence, and a commitment to justice that runs deeper than winning. Her mediation practice and civil rights advocacy reflect the same conviction: that process matters as much as result, and that healing, both between parties in conflict and across systems long shaped by inequity, is only possible when we hold ourselves to account. 

She earned her Juris Doctor from Loyola University Chicago School of Law and her Bachelor of Arts from Tufts University.

Taylor Loyden is an attorney, strategist, thought leader, and advocate who sees the law not just as a set of constraints, but as a tool for protection, alignment, and thoughtful innovation. As a psychedelic and plant medicine attorney, she helps clients turn visionary ideas into legally sound, strategically grounded realities. 

Her approach is shaped by a multidisciplinary background and a career that extends well beyond traditional legal practice. Before becoming an attorney, Taylor spent over a decade as a backcountry guide, wilderness therapist, instructor, medic, and naturalist. That work taught her to hold multiple realities at once: the safety of the person in front of her, the conditions of the land, the needs of a group, and the limits of what any system can anticipate, all of which continue to inform her legal practice today.

Taylor’s experience in ethnobotany, mycology, and Indigenous traditions offers further context for her work, supporting conversations that span science, culture, and policy. She brings a relational lens to legal strategy, bridging regulatory requirements with frameworks clients can operate within, defend, and sustain over time. Her interests center on the places where legal systems, Indigenous and ecological knowledge, and community practice meet, and on building frameworks of care that are accountable to each of the worlds they serve.

Taylor is the Principal Attorney at Terrapin Legal PLLC, a member of the Board of Directors of the Psychedelic Bar Association, and sits on various councils that inform psychedelic policy. She holds a Juris Doctor from the University of Idaho College of Law, as well as a degree in Environmental Business and Leadership from the University of North Florida.

Melissa Dean is an Associate Attorney at Minardi Law, where her practice includes
psychedelics, cannabis, religious liberty, civil rights, litigation, personal injury, and criminal defense.

She works with individuals and organizations navigating state and federal questions involving controlled-substances policy, government enforcement, and constitutional protections. Her litigation work includes federal civil-rights and religious-liberty matters arising under the Religious Freedom Restoration Act (RFRA), as well as appellate and amicus advocacy involving entheogenic religions and medical marijuana issues in Florida. Melissa’s plaintiff-side personal injury practice informs her interest in helping shape safer, more ethical, and more accountable practices in emerging psychedelic spaces. She believes lawyers in this field have a responsibility not only to help change the law, but to help build ethical systems around healing that protect cognitive, religious, and civil liberty while also promoting standards of care, accountability, harm reduction, meaningful access. Melissa was drawn to psychedelic and controlled-substances advocacy through early academic work on altered states, trauma, and drug policy, which led her to pursue law as a vehicle for reform. She graduated from Barry University Dwayne O. Andreas School of Law during the pandemic, became a member of The Florida Bar in 2021, and was selected in
2025 to participate in the Psychedelics Bootcamp at Harvard Law School’s Petrie-Flom Center for Health Law Policy, Biotechnology, and Bioethics.

Melissa has been involved with the Psychedelic Bar Association since her first year of practice and now serves on its Board of Directors, where she contributes to its Litigation & Advocacy committee. She also serves in leadership with Decriminalize Nature Florida and previously represented the 19th Judicial Circuit on The Florida Bar Young Lawyers Division Board of Governors.
