Tina Rasmussen, PhD, Founder, Guiding Teacher, and Executive Director

Tina’s warm style, bright clarity and supportive presence helps students recognize their deeper nature, both on the cushion and in daily life. She has a decades-long commitment to cultivating her own and others’ deep spiritual unfoldment and human potential while functioning in an embodied, worldly life.

Dr. Rasmussen learned to meditate in 1976, at age 13. In 2003, after many years of practice in Buddhist and modern non-dual traditions, she was drawn to undertake an intensive year-long solo retreat during which a profound awakening to a deeper reality occurred. In 2004, Tina took refuge with Tibetan Dzogchen teacher Tsoknyi Rinpoche, and was initiated into the Nyingma lineage. In 2005, Tina attended a 2-month retreat with Burmese meditation master Ven. Pa Auk Sayadaw, who ordained her as a Buddhist nun and gave her the dharma name “Ayya Pesala.” During the retreat, Tina became the first Western woman to complete the entire detailed Samatha path in this lineage.

As an offering of gratitude to the dharma, Tina (along with Stephen Snyder) wrote the book, Practicing the Jhanas, which was later published by Shambhala Publications. In 2007, Tina became the first Western woman authorized by Ven. Pa Auk Sayadaw to teach.

After these life-changing experiences, at first Tina felt a strong pull to become a “cave yogi” and turn away from householder life to abide in the peace of Truth. However, over time, the possibility functioning from realization while living in the dynamism of the modern world became a more compelling life’s path. Tina then began participating in the Diamond Approach, a contemporary wisdom path designed for householders, that integrates the psychological and the spiritual into one continuum for living “in the world but not of it.” Tina has been studied by Yale Neuroscience Lab for research on the effects of meditation on consciousness and the brain, has been featured in “Awakening Women,” Non-duality Magazine, Conscious TV, Buddha at the Gas Pump, Buddhist Geeks, GuruViking, After Awakening, the Imperfect Buddha, Rick Hanson’s Wednesday Meditation, Deconstructing Yourself, and others.

Dr. Rasmussen now leads retreats and offers spiritual guidance and mentoring to practitioners worldwide. She has a PhD in human and organizational development, and worked as an executive coach and consultant in the business world for more than 25 years. She is also the author of several published books on humanistic business practices.


Mimi Maduro, MS, Assistant Teacher

Mimi feels rooted and at home in both the Theravadan and Vajrayana Buddhist traditions.  She began to formally meditate while traveling in Asia in 1987 connecting to Ajhan Chah and the Thai Forest tradition.  Vipassana meditation and hatha yoga were her daily practices in the years establishing her career in management and leadership for workforce and post-secondary education organizations.

In 2005 after meeting her root teacher, A.dzom Paylo Rinpoche, she took Bodhisattva vows immersing herself in the Vajrayana path including ngandro preliminaries, deity yoga, drupchens, tsa lung, tummo and Dzogchen. At this time she and her husband moved from an urban neighborhood to land outside a small rural community in Oregon which cultivated a love of silence, walking in the woods, and a steadfast commitment to awakening and meditation as a way of being.

Each year Mimi was able to spend weeks in group or solo retreat allowing her practice continued to deepen while working full-time, writing poetry and volunteering. Passionate about learning she certified as a professional coach focused on embodiment practices while continuing to work with her own personality material.

After retiring in 2015 silence and stillness guided her to Samatha and Trekcho meditation, Qi Gong and Focusing as her primary practices. In her ongoing quest to integrate realizations on and off the cushion, she began exploring consciousness, non-duality and neuroscience. She is certified as a Unified Mindfulness (UM) Level 2 coach, a secular meditation program developed by Shinzen Young and Julianna Raye.

Several years ago she gravitated to practicing Samatha and the jhanas as if completing a circle.  She discovered Tina’s teachings and book, and began training with her in retreat and in spiritual guidance sessions.

in retreat.  As a Luminous Mind Sangha assistant teacher, Mimi’s primary role is in assisting Tina with in-person retreats at Cloud Mountain Retreat Center. She also co-designed and offers the LMS Meditation Jumpstart program, and provides guidance to people on “Retreats-in-a-Box” and solo retreats.

Per Jobs, MFA, Teacher-in-Training

Per was born in Sweden and started his career as a performer and composer of jazz music, completing a Master of Fine Arts at the Royal University College of Music in Stockholm. After some time in this field, his love of nature drove him into nature-based, sustainable tourism. Per operates several lodges in remote areas of the Swedish Lapland mountain range, and acts as a coach and lecturer on eco-tourism and sustainable destination development. This line of work allows Per to spend a lot of time in the outdoors, which has been nurturing and dear to him all his life. Per also loves to grow things permaculture style in his large countryside garden on the Swedish island of Gotland, and works towards being more self-sufficient. He navigates a busy lay life, providing for a family, managing a business etc., while trying to live as ethically as possible.

After some spontaneous spiritual experiences prior to meditating, once Per started meditating he rapidly made practice a big part of his life, in terms of retreats, studies, and daily practice. He has an unbroken practice of several hours per day since 2015, in which Samatha practice has played a central role. In dedicated Samatha retreats with Tina, his practice has progressed to include many attainments. He has also spent several retreats focusing on heart-based and open monitoring practices.

Per finds inquiring into personal patterning, integrating realizations, and merging practice and its fruits into lay life, to be a great adventure. Per is training under the guidance of Tina Rasmussen, PhD, for authorization in the lineage of renowned scholar and meditation master Ven. Pa Auk Sayadaw of Myanmar. His focus of Teacher Training will be on offering dharma talks and daylongs, especially for practitioners in Europe.

Henry Garcia, MS, Teacher-in-Training

Henry was introduced to his spiritual path when he learned subtle energy work (similar to Reiki) towards the end of high school. With a love of philosophy, psychology and science, he headed off to college where he completed a bachelor’s degree in computer science and physics with a minor in mathematics from California State University, Sacramento. With a fascination and curiosity about how the universe works, Henry entered U.C. Berkeley to pursue a PhD in physics. He spent three years doing research in nanotechnology and nanodevices resulting in numerous publications, including being featured in Scientific American for helping to create a functioning nanoscale radio.

Before completing his PhD, Henry left U.C. Berkeley with a master’s degree to begin a career at Pixar Animation Studios. Since 2008 he has been working as an Effects and Simulation artist on roughly 20 films and shorts including Up, Toy Story 3 and 4, Brave, Inside Out and Luca. Henry is currently a supervisor at Pixar where he finds great joy in bringing to life stories that touch the hearts and minds of the world.

Henry was introduced to mediation and yoga (asana) practice through classes that were offered at Pixar. Observing first-hand the benefits of his practice and reading the research in neuroscience and psychology inspired Henry to go further. He dove headfirst into mediation starting with a 2-day Samatha retreat at Spirit Rock with Tina. Shortly after, he attended a 5-day Vipassana retreat, during which he had his first awakening experience, causing the priorities in his life to shift and his daily meditation practice to begin. He later attended Tina’s 2-week Samatha retreat, at which time his deeper spiritual path began to unfold. He has attended numerous retreats on different practices since then, which have rounded out his practice path.

With a big open heart and deep gratitude for the Brahmaviharas, Henry brings love and joy to the teachings. He is interested in the pursuit of awakening usinga balanced approach to insight, serenity and the jhanas, the heart practices, and western scientific approaches in a way that resonates with the western culture he lives in. He enjoys reading the latest scientific research on meditation and incorporating it into his teachings.

With his wife, three children, two cats, dog and demanding career, Henry has a busy householder life, but he still finds time to have a robust meditation practice in addition to attending several meditation retreats each year. Henry’s Teacher Training will begin with dharma talks, daylongs, and assisting Tina with retreats–especially focused on neuroscience research into meditation, as well as the Bramaviharas.

Marisa Mohrer, LMSW, MPH, Professional Affiliate

Marisa (she/her) sat down to formally meditate in the midst of an overfilled graduate school schedule. As a therapist trainee in community mental health committed to reducing human suffering, she first learned about the psychotherapeutic applications of mindfulness to support her clients. Marisa was surprised when she began to experience meditation firsthand, and noticed the potent effects of focused-attention and heart-based practices. After completing a dual Master of Clinical Social Work and Public Health degree at the University of Pennsylvania, she undertook a period of intensive silent meditation training. Through the engagement of meditative practices, she gradually began to peel back the layers of ingrained concepts that overlay a unified reality. At that point, the infinite nature of mind and reality opened up, powerfully shifting her identity and her perception of all that exists. Her book, Songs of Awakening, now available for purchase at https://www.marisamohrer.com, describes the integration of this experience. Marisa’s time spent in silent retreat galvanized her unwavering commitment to meditation, not only as a practice, but as a way of life.

After years of extensive study with Tina Rasmussen, Marisa now serves as a Professional Affiliate for Luminous Mind Sangha. As a Licensed Clinical Social Worker, she is dedicated to the daily, deepening embodiment of what she has experienced through meditation. She combines this commitment with her passion for evidence-based trauma therapy modalities (including Eye Movement Desensitization and Reprocessing or EMDR). Marisa completed a year-long postgraduate fellowship at The Trauma Institute in Northampton, MA, where she worked as an Intensive Trauma Therapist. She is now in private practice, specializing in working with meditation practitioners who are integrating nondual and awakening experiences, and seeking to heal trauma. She offers half and full day trauma therapy intensives, as well as ongoing therapy, serving the states of Massachusetts and Maine. To learn more, visit https://www.marisamohrer.com.

Jennifer Wheeler, MA, Spiritual Friend Emeritus

For many years, Jennifer helped students of Luminous Mind Sangha through offering 1:1 sessions individually and through the Mentoring Program, as well as offering solo retreat guidance via “Retreats-in-a-box.” She also taught the Meditation Jumpstart program with Mimi Maduro.  Jennifer brought to her work with others the understanding derived from her spiritual experience and from her formal and academic training, as well as a sincere curiosity in and heartfelt appreciation for the unique way in which spirituality unfolds in each individual. Jennifer also was a tremendous help in establishing Luminous Mind Sangha behind-the-scenes for many years, and we are forever grateful.

Jennifer began meditating in 1998 and received her first formal instruction in 2001 at a Japanese Zen temple. She practiced subsequently in the Vietnamese Zen tradition, in which she was authorized as a lay Dharma teacher and then took ordination as a monastic for several years. During that period, she also received a master’s degree in Buddhist Studies. She attended many retreats with Tina and Stephen and other lay and monastic Buddhist teachers over the course of many years.

After finding that not all her experience could be contained within Buddhism, Jennifer explored other paths including Advaita Vedanta and the Diamond Approach, practicing many forms of meditation including Samatha, open awareness, the Brahmaviharas, chanting and recitation, movement meditations, and Diamond Approach meditations, among others. Jennifer has now devoted herself to her own practice, residing in her home in a small town in South Carolina, where she stays close to the land and enjoys her neighbors, family, and the animals with whom she shares her life.
