About Us
Meet The Team
We're an internationally experienced team of chiropractors and educators, spanning Europe and North America, dedicated to sharing BioGeometric Integration® with chiropractors around the world. Together, we bring over a century of combined clinical and teaching experience — building bridges between structure, philosophy and human connection, one seminar at a time.
“BGI® is not about teaching chiropractors to imitate someone else's way of adjusting, but about developing awareness, curiosity and mastery so that each chiropractor can more fully discover their own gifts.”
Amy Burke, D.C.Lead Steward, BGI Europe Seminars®
Sue Brown, D.C., was the founder and developer of Bio-Geometric Integration® (BGI®). An extraordinary clinician, devoted to the discovery of how and why things worked, and evolved in her practice, on the table, and in the world around her, Sue developed BGI® as a framework for understanding the body, subluxation and the chiropractic adjustment.
At the core of BGI®, is Sue’s own: Potential Energy Theory of Subluxation. PETS describes subluxation as stored, unintegrated energetic experiences containing potential for learning, healing and evolution. She also mapped out the body’s innate geometry as a way to understand and predict how and where the potential energy of each subluxation could best be accessed and released. Sue’s work is the foundation of Bio-Geometric Integration®.
Building bridges between Tonal, Structural and Postural techniques is the tagline developed over 25 years ago to describe the ethos of BGI®. Embracing and empowering people to express their greatest potential remain at the heart of the work.
Valerie Pennacchio, D.C., is a BGI® Master, educator and longtime leader in chiropractic education whose relationship with BioGeometric Integration® reaches back to its formative years with founder Sue Brown, D.C. Valerie’s heralding of the beauty and importance of the work ensured BGI® had a place in the curriculum of NZCC and McTimoney.
A 1990 graduate of Sherman College of Straight Chiropractic, Valerie went on to an extensive career in chiropractic education, teaching philosophy and imbuing courses that otherwise might have been mechanical at best, mechanistic in all probability, with her incredible skill of weaving philosophy (and BGI®) into every conversation and interaction. Her professional roster includes Sherman, Palmer, Florida, New Zealand College of Chiropractic, and most recently, McTimoney College of Chiropractic where she served as Vice Principal and MChiro Programme Leader.
Valerie also holds a particularly important place in the history of both BGI® and BGI Europe Seminars®. Together with Sue, Amy Burke, D.C., and Holly Hochstadt, she helped craft the Mission and Vision statements for BGI®, giving both structure and purpose to the work. Though Valerie is no longer active in a teaching role, she remains the keel and the anchor to our ship—guiding, steering, and providing her wisdom and vision.
Valerie, aka Velvet Hands, is a mean line dancing machine, and has been known for her generosity in giving out toasters. Her dedication to our profession and her artful ability to bring integrity into a room of chiropractic sharks is unparalleled.
Amy Burke, D.C., is an internationally experienced chiropractor, educator, and Lead Steward and owner of BGI Europe Seminars®. She has been sharing BioGeometric Integration® with chiropractors and chiropractic students for more than two decades.
Amy graduated with high honors and Phi Beta Kappa from the University of California, Berkeley, and received her Doctor of Chiropractic degree from Life Chiropractic College West in 1999. Before becoming a chiropractor, she spent ten years working as a massage therapist—an experience that helped develop the sensitivity to touch, the body, and human connection that continues to inform her work today.
Amy was introduced to BioGeometric Integration® in 1999. When Sue Brown, D.C., founder and developer of BGI®, began expanding the teaching of her work, Amy became part of Sue’s early Staff Training program in 2001–2002 and was specifically trained by Sue to teach BGI®. Her clinical experience enhanced the lives of babies and elders and everyone in between on two continents. Her teaching has helped generations of chiropractors explore the philosophy, geometry and hands-on application of BGI®.
Amy brings a distinctly down-to-earth, playful and experiential quality to her teaching. She believes that BGI® is not about teaching chiropractors to imitate someone else’s way of adjusting, but about developing awareness, curiosity and mastery so that each chiropractor can more fully discover their own gifts. Her particular talent—and what she calls her “superpower”—is connecting people.
Today, Amy continues to practice in Italy while stewarding BGI Europe Seminars® and the growing international community of chiropractors who learn, practice and evolve together through this work. She brings the quirk to the game and loves socks and tacos, maybe not in that order.
Tonya Tyre, D.C., is a BGI® Master, Lead Steward of BGI® Canada, international educator, and developer of the Internal Geometry—work that expands upon the principles and geometric understanding at the heart of BioGeometric Integration®. She has been pushing the boundaries of what is known and understood through her teaching for more than 15 years.
Tonya graduated from Canadian Memorial Chiropractic College in Toronto in 2002, following undergraduate studies in Immunology. Her interest in chiropractic grew from an early desire to work with people through her hands and from a recognition of the inherent wisdom of the body. Over time, that curiosity developed into a particular fascination with the relationship between structure and physiology.
Her clinical work reflects that breadth of curiosity. Practicing in British Columbia, Canada, Tonya works with people across the lifespan, from newborns onward, and has particular interests that include pediatrics, women’s health, cranial concerns and concussions. She divides her professional life between clinical practice, family and teaching continuing education to chiropractors.
Within BGI®, Tonya has become both a highly experienced teacher and an explorer of where the work can go next.
Tonya’s contribution extends beyond her teaching and her encouraging presence: through the Internal Geometry and the seminars she has created, she continues to investigate the relationships between geometry, structure, physiology and the adjusting process—bringing new questions and discoveries back into both her teaching and her clinical practice.
Tonya brings depth, precision and an irrepressible curiosity to her teaching. Her work honors the foundations of BGI® while embodying one of Sue Brown’s most important legacies: that mastery is not static. It invites us to keep exploring, questioning and discovering what else may be possible.
She is a karaoke queen.
Tara Dennis, D.C. is a chiropractor, international educator and longtime practitioner of BioGeometric Integration®, bringing a deeply curious and integrative approach to chiropractic, the nervous system and human development and evolution.
Originally trained at the New Zealand College of Chiropractic, Tara graduated in 2014 and has since developed a broad approach to practice informed by her continuing studies of the ways our physical, emotional and energetic experiences are expressed through the body.
Her interest in the nervous system and childhood development began early in her chiropractic career. While still at the New Zealand College of Chiropractic, Tara co-authored a published case report examining chiropractic care and developmental changes in a four-year-old child with dyspraxia and associated developmental delays.
Today Tara practices in Amsterdam, where she works with people through an approach that recognizes the body as an interconnected and continually adapting system. Her understanding of BGI® emphasizes geometry, energy, resonance and vibration as ways of perceiving the patterns through which the body organizes and integrates experience.
She brings to her seminars the perspective of someone who is continually studying, questioning and integrating ideas from many different areas.
Tara brings warmth, giggling, playfulness and an infectious curiosity to BGI®. Her teaching invites chiropractors to explore beyond what they already know—to become more perceptive, more adaptable and more confident in following the intelligence of the system in front of them. She is the barefoot queen of testing the waters in every way, both literally and figuratively.
Peter Lambert met Sue Brown in 2005 and immediately became her supporter in very practical ways such as seminar set up and transportation. He is the master of BGI Europe Seminars® logistics and offers unwavering support, technical assistance, guidance, dad jokes and recipes to anyone having difficulty navigating any aspect of their BGI Europe Seminars® experience. He is responsible for updating much of the teaching material, from visuals in the notes to the creation of Bonesey, a 3-D model AR that shows the geometry in ways we couldn’t have imagined when all this started 25 years ago. He and Amy have been married since 2005.
Nouman Rasool took some vague ideas and a lot of passion and crafted this beautiful site. We had never met or spoken, yet through our back and forth, he started to add pieces that were perfect, demonstrating that he “got” what I was trying to describe and found a way to convey it that is clean, elegant, professional and exciting.
BGI Europe Seminars® is tremendously grateful for his efforts, skill and patience.
