This week on the Good Medicine Podcast, Dr. David Bearss sits down with Dr. Evan Unger, physician-scientist, serial biotech entrepreneur, and pioneer in therapeutic oxygen delivery technologies.

Dr. Unger has spent decades working at the intersection of medicine, physics, and innovation. His work has focused on developing technologies that improve how oxygen is delivered to tissues in critical conditions such as cancer and heart attack. Tumor hypoxia, a state where parts of a tumor are deprived of adequate oxygen, has long been recognized as a major barrier to effective radiation therapy. Hypoxic tumors are more resistant to treatment, which can limit outcomes. Dr. Unger discusses why this problem has persisted since it was first described in the 1950s and why he believes his current work may represent one of the first meaningful approaches to reversing tumor hypoxia.

The conversation also explores the realities of being an inventor and biotech founder. Dr. Unger reflects on how having too many ideas can become a liability, and why focus, regulatory strategy, market opportunity, and disciplined value creation are essential for translating innovation into impact.

Finally, he shares why he remains driven by the possibility that new approaches to oxygen delivery could fundamentally transform treatment for heart attack, still the leading cause of death in the United States. This episode is about persistence, disciplined innovation, and pursuing breakthroughs that could change outcomes at scale.

This week on the Good Medicine Podcast, Dr. David Bearss sits down with Olympic gold medalist Peter Vidmar to talk about excellence, discipline, and the lifelong impact of exercise.

Peter reflects on his journey to Olympic gold, the influence of a coach who emphasized fundamentals above everything else, and how mastering the basics accelerated his growth. He shares how his love for gymnastics began at a young age and why he never cared whether his peers understood his passion.

The conversation also explores Peter’s work with the “Ready, Set, Gold” program, where Olympians partnered with schools to inspire young people to improve their physical fitness. He discusses the powerful connection between physical activity, mental health, and long-term well-being.

From elite competition to everyday fitness, this episode is about consistency, discipline, and finding movement that works for you.

With more than 25 years of experience across clinical medicine, venture capital, entrepreneurship, and executive leadership, Dr. Greenberg shares how operating under uncertainty in the emergency room directly prepared him for leading companies through high-stakes decision making.

They discuss the realities of clinical trial execution, the challenges of recruiting patients in acute care settings, and why innovation in medicine remains one of the most demanding yet rewarding fields to work in.

This episode is about resilience, adaptability, and the drive to solve unmet patient needs at scale.

This week on the Good Medicine Podcast, Dr. David Bearss sits down with Josh Miller, CEO of Biologic Input Output Systems, Inc. (BIOS), to talk about groundbreaking work at the intersection of neuroscience, engineering, and human connection.

BIOS develops advanced neural interface technology that allows the nervous system to communicate directly with machines. Their work focuses on restoring movement, sensation, and function by translating brain signals into action and, in some cases, returning sensory feedback back to the brain.

In this conversation, Josh shares deeply moving stories from clinical trials, including a woman who was able to feel and control a virtual hand simply by thinking about it after years without an arm. He also explains why BIOS chose to start with upper limb prosthetics, one of the most complex challenges in neurotechnology, and what it means for people who have lost the ability to do simple but meaningful things like holding a loved one’s hand.

The episode also explores how BIOS technology could help block pain signals in the nervous system, opening the door to entirely new approaches to pain management.

This is a conversation about science that restores dignity, independence, and hope.

In this episode of the Good Medicine Podcast, Dr. David Bearss sits down with Dr. Jim Hotaling and Dr. Brad Cairns from Paterna Biosciences to talk about a new way of thinking about male infertility.

Dr. Brad Cairns explains that in many cases, stem cells themselves are not the root of the problem. Instead, the issue lies in the supporting or chaperoning cells that guide stem cells through normal development. Paterna’s work focuses on restoring that developmental process rather than replacing cells outright.

The conversation also explores how Paterna is developing approaches to help men with infertility at many different stages, offering options even when traditional treatments have failed. Dr. Jim Hotaling shares the deeply personal side of this work, reflecting on his role in delivering life altering news to families and how that responsibility drives his commitment to building better solutions.

This episode blends cutting edge science with the human reality behind infertility and why progress in this space matters so much.

In this episode of the Good Medicine Podcast, Dr. David Bearss and Dr. Jeremiah Bearss take a hard look at Alzheimer’s disease through the lenses of caregiving, economics, and the future of medicine.

They discuss the immense burden Alzheimer’s places on families and the economy, why treating the disease after it has fully developed may be too late, and how precision medicine could help identify people at risk long before symptoms appear.

The conversation also looks ahead to what the next phase of Alzheimer’s research may focus on, shifting from reacting to damage toward preserving brain function decades earlier. This episode is about understanding the full cost of Alzheimer’s and why prevention may be the most important step forward.

In this episode of the Good Medicine Podcast, Dr. David Bearss and Dr. Jeremiah Bearss look ahead to what 2026 could bring for medicine, public health, and drug development.

They discuss early data suggesting major reductions in tuberculosis progression, how inflammation may reshape the way we treat cardiovascular disease, and why AI guided precision clinical trials are likely to become the norm. These changes could dramatically reduce cost, speed up development timelines, and improve success rates across medicine.

This conversation is about where the field is headed next and why the coming years may look very different from the last decade.

This week on the Good Medicine Podcast, Dr. David Bearss sits down with Ryan Morley from Springtide Ventures to talk about early stage investing, entrepreneurship, and what it takes to build companies that truly improve human health.

Ryan explains how Springtide focuses on partnering with early stage companies in health and life science technology, working closely with founders as they build and scale. Their approach is not just about capital, but about long term collaboration and helping companies navigate the complex healthcare ecosystem.

The conversation also dives into purpose driven entrepreneurship. Ryan shares why so many founders he works with are motivated by deeply personal experiences and how that purpose shapes stronger companies. They close by discussing why understanding the end customer and aiming to elevate human health, not just incrementally improve healthcare, is critical for lasting impact.
