Regenexx stem cell procedures have been studied extensively for more than a decade and our patients are part of the world’s largest human mesenchymal stem cell re-implantation database for orthopedic purposes. We are the only orthopedic stem cell providers with this volume of data to draw upon and to regularly summarize outcome data from our patient registry and make it available to the public.

Scott Lane

Great experience from the start Dr. Torrance and the staff reviewed every step of the procedure and followed up several times. Its been six months since my procedure and the results have been amazing! I would highly recommend to explore the Regenexx process before knee replacement, its worth the research!

Steven Masley, MD

Dr. Leiber provides a very comprehensive evaluation, an expert action plan, and is a national leader in state-of-the-art procedures using stem cell and PRP therapies. I have seen him for several procedures on different joints and have had excellent results. This office is highly recommended!--Steven Masley MD

Amanda Kinney

The staff here are amazing and friendly. They are always patient, kind, and helpful. Dr. Leiber is a wonderful and highly skilled physician. After being told by a physician that surgery was my only "real" option for my back problems, I am glad that I went to Regenexx instead. I am currently undergoing treatment and have seen improvement and pain relief after my treatments. I absolutely recommend Regenexx Tampa Bay!

Beth Howlett

All positive! Friendly staff. Accommodating and helpful. Excellent care and treatment.

Angie Rasner

The whole group was very helpful and friendly. Explained things thoroughly. They obviously know their stuff! Felt very confident scheduling a date for procedure.

Mark Kleinsmith

I’ve had several treatments at Regenexx over the years in both Tampa and Sarasota and they have been quite successful. Far far better than pursuing just pain relief as the treatments are focused on healing. Also far better than surgeries that come with additional risks. 6 years ago I was told by 3 different orthopedic doctors that due to my arthritis and athletic wear & tear on my knees and hips that I was getting close to needing joint replacements...I’m 65 now and my aches and pains in those joints are gone or insignificant. I find the doctors at Regenexx thorough, competent and caring.Cheers to keeping all my body parts 😀

Linda A Wood

Dr Leiber is a fantastic Regenexx Doctor. His staff is amazing-I flew from AZ to see them rather than go closer to CO because they are so accommodating and welcoming. My knee and thumb are doing amazing. Every day better after one month exactly. Run if you can- don't walk to Dr Leiber because surgery is old school and he is the BEST!

Kathleen Andrews

Dr Lieber is the best doctor! He is honest, competent & caring. I was bone on bone and needed knee replacement--but thank goodness for REGENEXX and Dr Lieber! When I heard about him I decided to give it a try. My knee is so much better. My husband then had his left knee done and had great results as well. From shifting my weight to my other knee before I had the stem cell on my right knee I managed to tear my ACL & PCL causing my knee to hyper extend. Dr Lieber gave me a stem cell procedure in that one as well. It has only been 6 weeks and I can't believe how great my knee is! Don't have second thoughts--Regenexx stem cell procedure works!!

Jerry Powers

My shoulder was in rough shape. It felt fine as long as I did not do anything with it. Once I had the procedure done and then completed the rehab, my shoulder is really healthy now. It is up to about 95% strength now. I can lift bags of concrete. I can do push ups too. Not a bunch of them, but I couldn't even do 2 before.

nice nunes

I highly recommend Regenexx Tampa Bay. I had stem cell treatment, PRP done to my lumbar, thoracic and cervical. Great staff, extremely professional, attentive, friendly and loving. Thank you Dr. Leiber

Nancy Gomez

I had Doctor Torrance. He was very knowledgeable and very detailed regarding the procedure. I was very comfortable with him. Thanks Doctor Torrance.

William Brannon

I have trusted Dr. Leiber with my knees and shoulders for years. He is a caring doctor and has a really nice staff as well. My knees were hot and inflamed when I went to him but they are now cool to the touch and letting me exercise regularly. He has also helped me with an old shoulder injury.

JUST AMAZED> Hubby and I ride motorcycles (street/MX), we're also active athletically. We are a young 50, & want to remain active. I've had 6 traumatic accidents, my most recent was in 2017(16 fractures) I was unable to bend or twist and I went to bed in pain, & woke up in pain. Dr. Torrance was sure I would benefit from PRP. Now, I'm in awe, (in fact, I am a little freaked out). I'm bending/twisting, and for the first time in years, I woke up today with NO pain, I actually cried happy tears. The entire Tampa office is amazing, friendly, professional, and personal. We can't say enough great things about Dr. Torrance, he is thorough, and informative, & knowledgeable. We investigated other facilities, & were both offered stem cells only, w/a ridiculous price tag. Dr. Torrance was the only one who suggested PRP, after a thorough exam. Also, he's the only Dr. to investigate/discover edema in hubbys femoral head(other ortho dr. offered to cut him open and give him a new hip that he doesn't need) If you are considering PRP or stem cells, Regenexx is your safe place.
