Prehab Before PRP: Dr Tammy Penhollow on Ethical Regenerative Medicine

Send us Fan Mail“How much is PRP?” is often the wrong first question. I’m joined by Dr Tammy Penhollow, an osteopathic physician and founder of Precision Med PRP, to talk about why regenerative medicine outcomes hinge on what happens before treatment not just the injection itself. If you’re dealing with spine pain, disc problems, knee pain or shoulder injuries and trying to avoid surgery, her message is simple: you cannot expect great results from platelet rich plasma or bone marrow concentrate if your body is running on chronic inflammation, poor sleep and missing nutritional basics. We dig into her prehab model: building an anabolic, healing state through sleep, protein, vitamin D and targeted lifestyle changes, guided by baseline labs and a functional assessment. We also discuss why dynamic ultrasound matters, why “chasing higher platelet numbers” can miss the point, and how expectations change when patients have multiple high quality touch points rather than a rushed, transactional consult. We also get honest about the current orthobiologics landscape, including the rise of bolt on regenerative services, the ongoing myths around PRP as a one time fix, and the need for ethical patient education as the field grows. If you’re curious about functional medicine, orthobiologics, and what high integrity regenerative care should look like, this conversation offers a clear framework you can use straight away. If this helped you, subscribe, share it with someone weighing PRP or surgery, and leave a review with your biggest takeaway.Guest BiographyDr Tammy Penhollow is an osteopathic physician based in Arizona and the founder of Precision Med PRP.
