Same-day autologous fat and PRP injections placed under ultrasound guidance, plus adipose stem cell banking through American Cell Technology

NW Regen is a cash-pay regenerative and interventional medicine practice on SW Upper Boones Ferry Road in Portland, Oregon, running since 2018 under founder Ryan Wood. The orthopedic side is the part that puts it in this directory: prolotherapy, platelet-rich plasma, and micro-fragmented adipose tissue grafting for damaged tendons, ligaments, and joints, every injection placed under musculoskeletal ultrasound or fluoroscopy. The cell therapy is autologous and minimally manipulated. Fat is harvested from the patient, micro-fragmented, and put back during the same visit, either into the joint or by IV. Nothing is culture expanded and no donor cells are used, which places the clinic in the same-day autologous category rather than the expanded-MSC market most offshore clinics work in. Wood holds the RMSK credential in diagnostic musculoskeletal sonography, and the practice also runs Digital Motion X-ray for craniocervical instability and upper cervical ligament injuries. Personal stem cell banking is the unusual part. NW Regen harvests adipose-derived cells and sends them to American Cell Technology, an FDA-registered current good tissue practice facility, to be cryopreserved in liquid nitrogen. Banked cells stay available for later injections and IVs at the clinic, which is the whole argument for banking at forty rather than at the point of need at sixty. Two things are worth knowing before you call. All three providers are naturopathic physicians and Wood also holds a chiropractic degree; there are no MDs or DOs on staff. And the highest-volume procedure in the building is not orthopedic at all, it is the stellate ganglion block, which Wood has performed more than 3,000 times for PTSD, dysautonomia, POTS, and long COVID. He teaches ultrasound-guided regenerative injection technique for the Hackett Hemwall Patterson Foundation and the European School of Prolotherapy and Regenerative Medicine. The office is open Monday through Thursday and closed Friday through Sunday.

No prices are published. NW Regen is cash-pay for everything it does and holds no insurance contracts, so fees are quoted after a consultation and scale with the length and complexity of the visit. A first appointment usually runs about an hour. HSA and FSA funds are accepted, CareCredit is not. The clinic issues superbills with procedure and diagnostic coding if you want to file an out-of-network claim yourself, though whether anything comes back is up to your insurer.

4.8out of 5 on Google from 75 ratings
A polarised listing rather than a uniformly warm one: 71 of the 75 reviews are five stars, the other four are one or two. Most of the volume is not orthopedic. The largest group came for stellate ganglion blocks for PTSD, C-PTSD, dysautonomia, POTS or long COVID, several driving down from Vancouver BC or flying in, and they describe Wood spending an hour or more explaining the procedure before touching a needle. The regenerative injection reviews cover prolotherapy and PRP for decades-old back injuries, knees, shoulders and Ehlers-Danlos instability, and they single out his diagnostic ultrasound again and again. Libby, the practice manager and his wife, is named almost as often as he is. The criticism is narrow and consistent: two patients were left waiting an hour or had a follow-up pushed and never called back, one found the price around 30 percent above comparable providers and higher on the day than on the consult call, and a hip osteoarthritis patient reported 13 months of relief before progressing to bone on bone. Several reviews still use the practice's former name, Northwest Regenerative Orthopedics.

Dr. Ryan R. Wood
Founder and Clinical Director
ND, DC, RMSK
Wood founded NW Regen and has practiced for close to twenty years. He is a licensed naturopathic physician who also holds a doctorate in chiropractic, and he carries the RMSK credential in diagnostic musculoskeletal sonography, which is the tool the rest of his practice is built around. His orthopedic work covers regenerative injection therapy, peripheral nerve entrapments and hydrodissection, and complex spine problems including craniocervical instability, where he pairs ultrasound with Digital Motion X-ray. Outside orthopedics he has performed more than 3,000 stellate ganglion blocks for PTSD, dysautonomia, POTS, and long COVID, which is among the highest counts anywhere. He lectures and teaches injection technique for the Hackett Hemwall Patterson Foundation and the European School of Prolotherapy and Regenerative Medicine, and publishes on ultrasound-guided nerve and autonomic procedures. Other clinicians refer refractory cases to him.
Dr. Alicia Hart
Integrative Physician
ND
Hart is a naturopathic physician who handles the clinic's mental health and complex chronic care. She diagnoses and treats ADHD in adults and in children aged seven and up, and works with anxiety, CPTSD, depression, and postpartum mood disorders. She also carries much of the connective tissue and dysautonomia caseload, including Ehlers-Danlos, MCAS, and POTS, using a mix of medication management, herbal therapy, and lifestyle support.
Dr. William Hibbitts
Naturopathic Physician
ND
Hibbitts focuses on chronic pain and psychedelic-assisted therapy, and performs ultrasound-guided injections alongside Wood. He came to medicine sideways. A trek through the Andean highlands, where children asked him for medicine instead of sweets, emptied his first aid kit and pointed him at global health; he went on to spend more than two years in Guinea, West Africa as a Peace Corps public health volunteer, working with village medical staff and learning plant medicine from a local Karamoxo.
