Leading Medical Professionals at Your Service
MD – Co-Founder and Visionary of Thrive Medicine
Dr. Rhet Langley
Dr. Rhet Langley is a practitioner who operates at the intersection of precision medicine, performance optimization, and human longevity—shaped by a career that spans military service, anesthesiology, and advanced pain medicine. He is known for taking patients far beyond symptom relief, guiding them toward the strongest, most capable version of themselves. He is board certified in Pain Medicine and Anesthesiology, earning distinction as Chief Resident during his training. After completing his medical training, Dr. Langley served in the United States Air Force, where he completed a combat tour in Afghanistan and learned the leadership principles that continue to define his clinical philosophy: discipline, clarity, adaptability, and an unwavering commitment to those under his care. These experiences forged the mindset he brings into medicine—one built on accountability, operational excellence, and a refusal to accept mediocrity.
His clinical philosophy is built on a simple truth: the body is designed to heal, adapt, and rise when given the right environment. To unlock that potential, Dr. Langley integrates regenerative therapies, metabolic diagnostics, performance medicine, peptide optimization, and elite recovery strategies—helping patients break through plateaus, overcome chronic limitations, and rebuild confidence in their physical capability. Patients come to him when they want momentum, clarity, and a path forward. Through structured systems, decisive communication, and practitioner-led protocols, he delivers care that is both deeply human and relentlessly results-driven. His mission is to elevate the standard of modern regenerative medicine—and to give every patient the tools, strength, and strategy to take command of their health. This is what THRIVE stands for: a clinic built not on passive healthcare, but on a performance-driven, warrior-minded pursuit of long-term human capability.
Out of the Office:
Dr. Langley lives with his beautiful wife Sarah and their lovable bulldog, June. He hopes that you will get to meet both soon, being part of the Thrive Family. He likes to laugh and makes others laugh. In his free time, you will find him in the Heights riding bikes with Sarah, lifting weights, or attempting to make sushi for the first time at home.
Co-Founder
Dr. Phillip Gallegos, MD
Dr. Joseph Gallegos is a board-certified anesthesiologist with advanced training from The University of Texas Health Science Center at Houston and a career defined by precision, innovation, and leadership. With deep expertise in ultrasound-guided nerve blocks and interventional pain management, he has helped countless patients find meaningful relief through techniques grounded in accuracy and intention. Throughout his career, he has served in pivotal leadership roles (including Chief of Anesthesia and Hospital Medical Director) and was recognized twice as a Top Doctor in Anesthesia (2018, 2021), a distinction earned through both technical mastery and unwavering commitment to excellence. But the defining chapter of Dr. Gallegos’ story isn’t found in titles or accolades. It began when he realized the cost of putting his career above his own well-being. Years of overwork and self-neglect pushed him into a state of burnout that demanded a choice: continue breaking himself down or take ownership of his health and rebuild. He chose the latter.
His journey through functional medicine, regenerative therapies, and ancestral health became more than personal healing—it became a catalyst. As he rebuilt his energy, strength, and clarity, he rediscovered the purpose that first led him into medicine: to help people rise, not just recover. Reuniting with his longtime colleague from residency, Dr. Rhet Langley, the two founded Thrive Medicine with a shared mission—deliver care rooted in precision and performance, elevate patients beyond symptom management, and help them reclaim the physical, mental, and energetic capacity to truly thrive. Dr. Gallegos brings a practitioner’s expertise, a leader’s discipline, and a survivor’s empathy into every patient interaction. His work is a testament to resilience, reinvention, and the belief that healing is not the end goal—thriving is.
Out of the Office:
Dr. Gallegos lives just outside Houston with his wife Katie, their spirited daughter Finley, two clever Basenjis (Captain Morgan & Clementine), a quirky cat named Alley, and a vibrant community of 75 freshwater fish. He and Finley share a passion for aquascaping, while he and Katie live as wellness role models for their daughter—leading by example in fitness and lifestyle. When he’s not with patients or family, you’ll find Dr. Gallegos in nature (hunting, fishing, or hiking) or immersed in his other passions: cooking, reading, exploring new cultures through travel, and vibing to electronic dance music. He’s also committed to giving back and participates in annual medical missions to provide care to underserved communities.
Head of Marketing & Creative
Ellen Renk
Ellen Renk brings over a decade of brand strategy, storytelling, and creative leadership to Thrive Medicine – translating complex concepts into messages that move people. She’s built campaigns, shaped narratives, and helped brands find their voice across multiple industries, but her best work lives where creativity meets impact and where stories actually change lives. As a lifelong athlete (D1 long and triple jumper, National Champion, and CrossFit Games competitor) Ellen has always lived at the center of performance, discipline, and possibility. She also knows the darker side of the health world: the pressure, the perfectionism, and the narratives that shrink people instead of strengthening them. After rewriting her own story and recovering from a six-year eating disorder, she rebuilt her approach to health from the ground up. She believed health should be focused on nourishment, self-respect, identity, and joy. That shift became the foundation of her coaching philosophy and the lens she brings into every project.
At Thrive, Ellen merges her creative skillset with her mission: redefining what it means to be well and helping people break free from the versions of themselves that no longer serve them. She crafts the messaging, brand experience, and content that make Thrive feel human, empowering, and deeply aligned with real transformation. Her role is simple: tell the truth, challenge outdated narratives, and help people see what’s possible when they stop settling and start taking ownership of their life, their health, and their story.
Out of the Office:
When she’s off the clock, you’ll find her running with her two dark red Golden Retrievers, making ceramics, exploring new places, or taking on a DIY home project that is slightly overambitious.
Head of Sales & Team Development
Robert Johnson
As Head of Sales and Internal Team at Thrive Medicine, Robert Johnson is the force that ensures every person who walks through our doors gets the clarity, direction, and confidence they need to transform their health. With an extensive background in high-performance coaching, executive leadership, and human behavior, Robert has spent years helping people take ownership of their lives—and he brings that same standard of empowerment to every conversation at Thrive.
Robert’s expertise sits at the intersection of strategy, communication, and human psychology. He knows how to help clients cut through confusion, understand their options, and choose the path that aligns with their goals. His mission is simple: make sure every individual—no matter their starting point—finds the solution that allows them to operate at their highest possible level.
Inside the clinic, Robert leads our sales and internal teams with a standard of excellence that mirrors the protocols we deliver. He ensures every touchpoint is intentional, every conversation is honest, and every client feels supported from the moment they reach out to the moment they experience real change. Under his leadership, the team operates with discipline, clarity, and a relentless commitment to follow-through. Robert brings a blend of directness, empathy, and high standards that pushes both clients and staff to rise. He believes people are capable of far more than they realize—and he’s here to make sure they have the strategy, support, and accountability to prove it. This is what he builds inside Thrive: a culture of ownership, empowerment, and a client experience that refuses to settle for anything less than transformative.
Out of the Office:
When Robert isn’t in the office you can find him at the gym chasing a new PR, traveling to check another National Park off his bucket list, or spending time with his two rescue dogs, Freya and Nova.

Stepping into THRIVE wasn’t a career move—it was alignment.

For her, family and wellness go hand in hand, and she brings that same energy and dedication into every patient interaction.
