Life of Flow

What makes a medical meeting worth leaving your practice for?
Another flight. Another familiar slide deck. Your staff and overhead keep running while you are away. If information is already in your pocket, what should a conference offer that you cannot get from your phone?
Rich Dubin, founder and publisher of Lower Extremity Review and the organizer behind lerEXPO, joins Dr. Lucas Ferrer and Dr. Miguel Montero-Baker to examine that question.
This conversation moves from the economics of the exhibit hall to the kind of learning that changes a physician's thinking. The details behind a difficult case. A question you would not ask from the back of an auditorium. A colleague who has done the work but never gets the microphone. And the relationships that a screen cannot entirely replace.
Together, they explore:
• Why access to information does not settle the question of a meeting's value.
• What time away really costs a physician whose practice still has to run.
• How faculty access can turn a presentation into a useful conversation.
• Why Miguel would rather learn in a circle than speak from a stage.
• How online education could lead into focused, hands-on learning.
• What an independent-practice mastermind might offer beyond clinical lectures.
• Why an audience-voted case tournament inspires the name “Vascular Hunger Games.”
Rich is not arguing that relationships have become obsolete. He values the handshake, the hug, and the unexpected introduction. The challenge is to give each format a purpose: online access, real discussion, and practical sessions for people who want to go deeper.
For independent physicians, the discussion becomes especially practical. Lucas imagines learning from people who have built successful practices. Miguel names the problems that deserve attention: cash flow, revenue-cycle management, a failing phone tree, and the business systems behind patient care. Their proposed gatherings remain ideas discussed in the episode, not announced courses or events.

What was the last meeting that changed how you work—and what made it useful?

Before you buy into an ASC, ask what you actually own—and who controls the decisions.

Dan Lieberman, MD joins Dr. Lucas Ferrer and Dr. Miguel Montero-Baker to unpack ambulatory surgery center ownership, the partners you choose and the agreements that shape your independence.

Dan trained in neurosurgery at UCSF, spent nearly two decades in solo practice and chaired the governing board of a physician-owned hospital. After essential tremor ended his operating career, his experience building ASCs became a new way to help physicians shape where and how they work.

Miguel brings the question many independent physicians hesitate to ask: after building a practice you control, why put your future in other people's hands? Dan's answer moves from the cost of taking a vacation to the financial model, exit arrangements and decisions physicians need to understand before signing.

In this conversation, Dan reveals:
⬛ Why owning a hospital made him rethink the environment in which he wanted to practice
⬛ How OBLs, ASCs and hospitals can serve different needs—and why patient selection comes first
⬛ Why owning your practice does not necessarily mean owning your time
⬛ What to ask about leaving a partnership before you agree to enter it
⬛ How to challenge a pro forma instead of treating its assumptions as promises
⬛ Why your ownership percentage does not tell the whole story about control
⬛ How the wrong partner can undermine an otherwise attractive business

The conversation ends with a practical checklist: understand the entity you would own, question the model, assess management, read the operating agreement and know your partners.

Which question would you insist on answering before buying into an ASC? Tell us in the comments.

A child should not need another open operation because an implanted blood vessel cannot grow—and a vascular graft should not become a surface where clot and infection win.Dr. Arush Kalra is a physician, biomedical engineer, co-founder and chief scientific officer of PECA Labs. He left pediatric-urology training after an attending told him, “Don’t play the game; make the game.” At Carnegie Mellon, he turned toward biomedical engineering and a strict rule: better technology should preserve a surgeon’s familiar craft instead of forcing the surgeon to relearn it.The origin was personal. Kalra’s mother has Marfan syndrome and a bicuspid aortic valve. Her progressive aortic disease pushed him toward cardiovascular materials. PECA began with expandable ePTFE conduits intended to accommodate growth in children, then asked an adult-vascular question: can a familiar graft be redesigned to resist thrombosis, reduce hyperplasia, retain antibiotics and still feel intuitive?Kalra describes the graft as a sandwich: the surfaces govern how the body responds, while the center supplies strength, flexibility and compliance. His team changes the microstructure of a material surgeons already know and inspects every graft with scanning electron microscopy. He discusses encouraging preclinical comparisons, but these remain investigational results—not clinical promises.In this conversation, Dr. Arush Kalra reveals:⬛ Why he walked away from the identity his family and training had built for him⬛ How his mother’s cardiovascular disease redirected his career toward devices that can grow⬛ Why the best invention may preserve a surgeon’s technique while changing the material underneath it⬛ How microstructure, elasticity and compliance influence thrombosis and anastomotic hyperplasia⬛ Why PECA is exploring antibiotic retention rather than a drug layer that disappears quickly⬛ Why patient safety demands imagining the worst outcome, not merely the most likely oneTimestamps:05:24 Growing up above a neonatal hospital06:46 His mother’s Marfan syndrome and aortic disease07:43 “Don’t play the game—make the game”11:54 Searching for a cardiovascular solution12:22 The design rule: do not make surgeons relearn their craft14:07 A graft designed to grow with a child16:28 The origin of PECA Labs17:28 The obsession with clot formation19:41 Engineering the layers of ePTFE23:21 Why Arush praises the FDA process28:19 Scanning every graft with electron microscopy45:22 Why mistakes are the fastest education46:58 Starting with peripheral vascular disease48:23 Patient safety before commercial focus52:37 Anti-thrombogenic and antibiotic development paths53:24 Designing for repeated large-needle puncture55:21 The antibiotic strategy discussed with regulators56:59 The inventor as artist, scientist and surgeonFollow Dr. Arush Kalra:LinkedIn: https://www.linkedin.com/in/arush-kalra-b4aa4750/PECA Labs: https://www.pecalabs.com/Resources mentioned in this episode:🏢 PECA Labs — expandable, radiopaque, anti-thrombogenic and valved polymer platforms🧪 ePTFE, scanning electron microscopy and microstructured vascular graft design🏛 FDA 510(k) and De Novo pathways as discussed in the recordingLife of Flow is hosted by Dr. Lucas Ferrer & Dr. Miguel Montero-Baker.🌐 Website: https://lifeofflowpodcast.com▶ YouTube: https://www.youtube.com/@LifeofFlowPodcast🎧 Listen: Spotify https://open.spotify.com/show/5GMv47SJ0ePxbjtIb1GZ5U · Apple https://podcasts.apple.com/us/podcast/life-of-flow/id1705596604📩 Partner with the show: info@lifeofflowpodcast.comConnect with the hosts:Dr. Lucas Ferrer — [Lucas LinkedIn]Dr. Miguel Montero-Baker — https://www.linkedin.com/in/miguel-montero-baker-a44354214/Follow the show: Instagram https://www.instagram.com/lifeofflowpodcast/ · X https://x.com/vascularpodcast · LinkedIn https://www.linkedin.com/company/lifeofflowEducational only; never medical advice.

Your title, schedule and reputation disappear in the jungle. What remains may be the first honest version of you that you have met in years.David Villanueva is the founder of Sukia Travel, a wildlife guide, adventure specialist and wilderness operator in Costa Rica’s Osa Peninsula. Michel Reijnen is a Dutch vascular surgeon who entered the expedition looking for a deeper experience of the jungle and returned with a different relationship to attention, identity and time.The Crucible is not a luxury retreat. Participants fly into Drake Bay, surrender familiar status, turn off their phones and travel roughly 100 kilometers through humidity, mud, rivers and steep terrain. They carry equipment, sleep in hammocks, journal, meditate and learn from indigenous guides, survival specialists, silence and the forest itself. David calls the underlying structure the FORGE protocol: leave the familiar frontier, meet a real ordeal, reflect and reframe the experience, cross a symbolic gateway, then return with a personal code.In this conversation, David and Michel reveal:⬛ Why a doctor, lawyer and executive become equals once everyone is exhausted and covered in mud⬛ How an ordeal can become empty adventure tourism unless reflection turns discomfort into meaning⬛ Why constant planning and replaying the past can quietly remove you from the life happening now⬛ What Michel discovered when he gave up his phone, camera and every connection to his ordinary identity⬛ How a 30-kilometer jungle day, river crossings and the “Witch Hill” expose the stories people use to survive⬛ Why fear should be recognized and processed rather than denied or muscled through⬛ How shared leadership, community and kincentricity challenge the Western obsession with the individualDo high performers need a place they cannot control to see what controls them?Timestamps:00:00 Pre-recording setup03:45 Welcome to Life of Flow07:22 David’s path into wildlife and adventure guiding08:48 Why the jungle strips away status09:46 The FORGE protocol for transformation12:36 Reflection, symbolism and the gateway16:09 What transformation actually means18:50 Inside the 10-Day Jungle Crucible23:02 The 30-kilometer day and the Witch Hill24:42 Roughly 100 kilometers through the jungle26:10 Kincentricity and the technology of cooperation43:34 The happiest and most frightening moments45:47 Getting lost without clean water48:29 Purpose, fear and leadership under pressure52:16 Michel’s edge in the jungle56:08 Who may need an experience like this58:07 How to find the Jungle Crucible60:28 Why David limits the number of expeditions61:32 Closing thoughts...Follow the guests:David Villanueva and the Jungle Crucible: https://sukiatravel.com/the-jungle-crucible/Michel Reijnen: https://www.linkedin.com/in/michel-reijnen-060991aa/Resources mentioned in this episode:🏢 Sukia Travel: https://sukiatravel.com/🌿 Costa Rica’s Osa Peninsula and Corcovado National Park📚 Carl Jung’s work on archetypes and the collective unconscious🧭 The FORGE protocol, journaling, meditation and symbolic rites of passage🤝 Kincentricity, community, shared leadership and reintegrationLife of Flow is hosted by Dr. Lucas Ferrer & Dr. Miguel Montero-Baker.🌐 Website: https://lifeofflowpodcast.com▶ YouTube: https://www.youtube.com/@LifeofFlowPodcast🎧 Listen: Spotify https://open.spotify.com/show/5GMv47SJ0ePxbjtIb1GZ5U · Apple https://podcasts.apple.com/us/podcast/life-of-flow/id1705596604📩 Partner with the show: info@lifeofflowpodcast.comConnect with the hosts:Dr. Lucas Ferrer — [Lucas LinkedIn]Dr. Miguel Montero-Baker — https://www.linkedin.com/in/miguel-montero-baker-a44354214/Follow the show: Instagram https://www.instagram.com/lifeofflowpodcast/ · X https://x.com/vascularpodcast · LinkedIn https://www.linkedin.com/company/lifeofflowEducational discussion only. The Jungle Crucible is physically and psychologically demanding, uses screening, and is not medical care or therapy.

Surgeons measure fistulas with precision—then send them into a dialysis-unit “black hole” where the same injury cycle starts again.Dr. Erin Moore is a Jacksonville vascular surgeon and former Navy physician who left roughly 15 years of military medicine for private-practice independence. There he owned high-volume dialysis access—about two to three hundred fistulas and grafts a year—and later became VP of clinical affairs around chair-side access-mapping software he names Veristra.This is not a war-story sequel. It is the systems problem behind failing dialysis access: thin tech training, on-the-job habits, high turnover, missing longitudinal stick history, area puncture as default, and a field that overbuilt stents and balloons while underbuilding the moment the needle hits the arm. Moore softens the old “micrometer vs ax” joke—staff are not trying to wreck access; they often lack tools, time, and information. His fix is mundane on purpose: photo + QR scale, mark arterial and venous sticks, color-age recent marks, and heat-map hotspots so the chair regains memory.In this conversation, Dr. Aaron Moore reveals:⬛ Why the unit becomes an information black hole after a surgical create⬛ How same-site puncture wears access toward pseudoaneurysm and failure⬛ Why rope-ladder is known to work—and still fails to become habit⬛ What a photo, QR scale, color-aged marks, and a fistula heat map change at the chair⬛ How pilot staff who only recorded points said they were still flying blind⬛ Why treating ~50% annual fistula patency as “OK” is a systems indictment⬛ What a 1973 patient-engineer already plotted on graph paper that centers still lackEducational discussion of workflow and systems—not individualized treatment advice.
