#140: Science vs Profit: Navigating Medicine, Money, and Morals. With Dr Brennen McKenzie
The Vet Vault: Veterinary Career, Clinical Skills & WellbeingShow Notes
Join us for the Vet Vault's own conference in the snow: Vets On Tour Wānaka, New Zealand, 10-15 August 2025!
Have you ever felt pressured, as a vet, to do more 'stuff' - diagnostics, procedures, and sell more, even when you can’t quite see the clinical justification for it? In this episode we welcome Dr. Brennen McKenzie-veterinarian, researcher, creator of the SkeptVet blog, author of Placebos for Pets? The Truth About Alternative Medicine in Animals, and all-round lover of science-based thinking. And who better to help us draw the line between solid science and revenue-driven decision making than someone who is known for their scepticism? Dr. McKenzie brings real-world wisdom and refreshing honesty to the debate. Together we explore the often-unspoken pressures of profit-driven care, commission-based pay, and what happens when business incentives conflict with good science. Brennen shares lessons from two decades in practice on how to use Spectrum of care reasoning to make clinical decisions that respect science, client resources, and the needs of your employer. A must-listen for any vet who’s ever questioned the system—and their place in it. Find out more about Brennen's current work in longevity at loyal.com.

A frightened cat in a cage. A vet who has to decide if it lives or dies, because the shelter is full, and a new batch of cats will be arriving on Monday. These are familiar situations for many vet teams - so much so that it can feel like just an unfortunate reality of veterinary work. But what if we’re thinking about it all wrong? If you don't understand the underlying cause of the problem, you’ll choose the wrong solution.
Why does a vet who's flat out every single day still hit a pay ceiling? Dr Andy Roark explains the hidden economics of veterinary practice, and an uncomfortable truth: the thing that makes us good vets might be the same thing holding our pay down.
Ask most vets what feedback means, and they'll think of a meeting. Once a year - maybe someone explaining that you're not billing enough. Dr Liv Oginska reckons that meeting is barely feedback at all. Because real feedback is happening all day: the look on your face when someone walks in, whether you say the thing you've been wrestling with for three weeks, or take it home and complain about it to your partner instead. There's a famous quote: 'The single biggest problem in communication is the illusion that it has taken place.' In this episode, we fix that. Liv shows what to actually say when someone goes straight to defensive, why you should never label their emotion, and the work you need to do on yourself first. Plus her practical advice on receiving feedback well. Dr Olivia Oginska is a vet, emotional intelligence specialist, certified workplace conflict mediator, lecturer at Murdoch University and founder of Human-Savvy. She's also just published research examining the links between feedback skills, psychological safety and turnover intention in veterinary organisations. In other words: does the way we talk to each other influence whether people want to leave? (Spoiler: it matters!) Somewhere in your practice there's a conversation nobody is having. It's already changing how everyone behaves. This episode is about having it.

What if the thing making your working day harder isn’t the workload? What if it's the building? In this episode we're joined by Jerry Kennard from Evoke Projects, someone who designs veterinary spaces for a living and has watched a lot of owners get this expensively wrong. Because a practice build always starts as a dream: the right location, the beautiful fit-out - the clinic you've always wanted. But plan it wrong, and that dream can quickly turn into a trap that stifles growth and demotivates teams . And most of it comes down to five mistakes that are a lot easier to avoid before you sign anything than after. In this episode, you'll learn: Why falling in love with your site might be the single most expensive mistake you can make The "too big or too small" problem, and how to future-proof for expansion without drowning in debt Why designing for the pet and the client but forgetting your team is a false economy How lean design and smart workflow let you do more in less space, without burning anyone out
Everyone says burnout. But Dr Sarah Golding thinks a lot of us are misdiagnosing ourselves. When vets come to her ready to walk away from the profession, they arrive with a vocabulary: burnt out, overwhelmed, imposter syndrome. Not one of them opens with the word Sarah reckons is often actually doing the damage: Fear. Fear of failing. Fear of the money conversation. Fear of the board, the Facebook post, the Monday morning debrief. And the big one, the one that shows up in almost every list she asks vets to write: fear of criticism, mostly from each other. Every fear you carry into a consult room was handed to you somewhere along your path - often by someone with good intentions - a teacher, a mentor, a friend. So we get into what to do about it. How to run a debrief that lets someone put a mistake down instead of carrying it for a decade. Why "don't worry about it, mate" is just as unhelpful as shouting. The difference between practising defensively and practising to help, and why clients can sense which one you are within seconds. Sarah's "debrief and dump it" process, complete with the literal bucket in her clinic that gets burnt at the Christmas party. And a small structural fix for the money conversation that has all but ended adult tantrums at her front desk. Dr Sarah Golding is a mixed practice vet in her second decade, principal practitioner and co-manager at Gowrie Vet Clinic in NSW, and this year a finalist in the NSW/ACT AgriFutures Rural Women's Award for her mentoring work through The Vet Mind Mentor. Somewhere in your career there's a case that wrote a rule about what you're good at, and what you avoid. This episode is about going back and reading that rule properly.
