The Arizona Regenerative Medicine Authority Guide
What patients (and physicians) need to know to avoid ineffective treatments and choose the right regenerative medicine expert.
Why This Page Exists
Regenerative medicine has transformed what’s possible for spine and joint pain, yet the field is filled with misinformation, shortcuts, and non-physician clinics offering “stem cell miracles” that have no scientific basis.
This guide was created to give patients clarity, accuracy, and protection.
I am Dr. Tammy Penhollow, DO, aNavy-trained physician, Stanford-trained pain specialist, national conference faculty, and founder of Precision Regenerative Medicine™.
My goal is to help you understand:
- what regenerative medicine actually is
- what it can realistically do
- what high-quality treatment looks like
- red flags to avoid
- and how to choose the right expert
The Problem: A Field Filled With Misinformation
- are not led by MDs or DOs
- inject without ultrasound or X-ray
- promise outcomes that are not medically realistic
- sell packages instead of providing diagnosis
- use unproven birth tissue or “stem cell” products
- treat only one structure instead of the whole system
Your Spine and Joints Are Organ Systems, Not Parts
Your spine and joints do not function as isolated parts. They behave as integrated systems.
The spine’s Functional Spinal Unit (FSU) includes:
- disc
- facets
- ligaments
- muscles
- nerves
- fascia
Your joints also operate as systems involving bone, cartilage, tendons, ligaments, meniscus/labrum, and stabilizing muscles.
Regenerative treatments only work long-term when the entire system is evaluated and treated—not one structure in isolation.
What High-Quality Regenerative Medicine Requires
- MD/DO trained in spine & joint diagnosis
- 10,000+ image-guided procedures
- Ultrasound and/or fluoroscopy for every injection
- Autologous PRP, BMAC, and micro-fragmented fat
- Treating the entire system, not one target
- No gimmicks and no sales pressure
- A physician who reviews your imaging personally
- A customized treatment plan, not a package
My Approach: Precision Over Promises
- a 60-minute physician consultation
- a full spine/joint + movement exam
- detailed review of your MRI/X-rays
- targeted diagnostic ultrasound
- personalized, evidence-based treatment recommendations
- image-guided precision procedures using prolotherapy, PRP, BMAC, or mFAT
- treatment of all relevant structures, not just one
- no-pressure education and honest expectations
How to Evaluate a Regenerative Medicine Clinic
- Led by an MD/DO
- Uses ultrasound and/or fluoroscopy
- Treats the full joint or spine system
- Uses only autologous orthobiologics
- Offers individualized treatment plans
- Reviews your imaging
- Does not guarantee outcomes
- Does not push packages
- Is transparent about training, experience, and results
When Regenerative Medicine Is the Right Choice
- degenerative disc disease
- discogenic pain
- facet joint pain
- SI joint instability
- osteoarthritis
- tendon and ligament injuries
- meniscal and labral support
- chronic joint pain not responding to conservative care
Why Patients Choose Precision Regenerative Medicine
- Clarity
- Honesty
- Precision
- A real diagnosis
- A real plan
- A physician who listens and gets it right
