OUR APPROACH
Clinical science applied with clinical discipline.
Regenerative medicine is a clinically active, evolving discipline that focuses on supporting the body’s capacity to repair and restore function at the cellular level. At OmniStem, that work is framed by physician evaluation, structured protocols, and realistic expectations.
Our primary biologics, umbilical cord mesenchymal stem cells (UC-MSCs) and UC-MSC–derived exosomes, are selected for their documented roles in immunomodulation, paracrine signaling, and intercellular communication.
How the biologics work
UC-MSCs are allogeneic cells derived from Wharton’s jelly of donated umbilical cord tissue after healthy full-term births. They are biologically young, immune-privileged, and characterized by their capacity to modulate inflammation and support tissue repair through signaling, rather than by replacing damaged cells.
Exosomes are nanoscale extracellular vesicles (30–150 nm) that carry concentrated regenerative signals, proteins, growth factors, and genetic material, capable of influencing how neighboring cells behave. Because they are acellular, they do not replicate and carry a lower immunological risk profile.
Mission
To produce and deliver pharmaceutical-grade cellular biologics through structured regenerative protocols that support recovery, promote resilience, and enhance long-term vitality, with integrity, transparency, and physician oversight at every step.
Vision
To restore health at the cellular level through precision biologics delivered within a controlled, medically supervised framework. Every protocol, every assay, every clinical decision is executed with the same discipline and quality standards that guide our laboratory operations.

Patient Testimonials
Personal experiences shared by patients who felt inspired to share their recovery.

They were the best. I was in the best care. It was worth the money spent. The stem cells were great. I felt the difference immediately. I was able to walk without a cane in less than three days. Every doctor was wonderful , the machines were great and the staff was top notch. They were very professional and they are with till the end. Omnistem I will recommend to anyone who needs them. I will always approve them. They are the best.

We have been 2 times. Hubby was able to avoid shoulder surgery and he went from bad daily pain, to completely a normal shoulder, started lifting again and heavy. Then his bicep tore. We just got back ad hope it works as well! The facility is FIRST CLASS for sure and the Dr’s are just incredible and very smart! we love that the lab is there as well. Carla and the rest of the staff are just a 12 on a scale from 1-10. Truly no words on HOW amazing all of them are. We have sent a few others there as well who have all had wonderful experiences and feel so much better! We will go back!

This is an incredible facility run by some remarkable people. I did months of research prior to deciding on where I would pursue regenerative therapy. I have micro tears in the ligaments in my back from military military service which cannot be cured through surgery or medical intervention. I’ve lived with constant pain for almost 2 decades now, and was looking for something that would relieve the pain and improve my quality of life. I would highly recommend this clinic both because of the quality of their stem cells, the quality of the care that they provide and incredible quality of the people that work that on these Omnistem.

I went to OmniStem to get treatment for my herniated disc in my lumbar spine and for my partial meniscus tear in my right knee. I found a caring and professional team doctors and health industry technicians that guided me through a very detailed process in preparation for my procedures. The equipment used in the facility is top of the line as well as the knowledge and expertise of the people using them. I am very happy I chose OmniStem for my treatment and decided to write this review hoping others can find the relief I did.

When arriving to Punta Cana, I had an appointment with Omni Stem to review my back issue. From the beginning they made me feel special and important, the treatment was 1st class. All doctors were very detailed in their information and knowledge, they walked me thru all options and the best way to heal. Special shot out to Vanessa, Dr. Paul, physical therapist Giovanna, nurse Luisana, Dr. Monica and front desk Ana all deserve 5 stars. I not only recommend this place, I stress to anyone who has back issues please reach out they will take great care of you and get you back up straight and running.

I had a great experience at Omni stem. I feel more energetic after the treatments. The staff is super friendly and professional and the place super clean and beautiful.

I came here with back and leg pain. I had 4 days of therapy including stem cells+exosomes for my back and total body. My pain is totally disappeared and I literally feel born again with full of energy. Thank you Omnistem people! Special thanks to Dr. Monica for a very successful spinal infiltration procedure.

For a year my shoulder was wrecked. A year of therapies, of trying things, of waiting patiently, and none of it changed anything. Then something happened that never had before: I finally understood what was actually wrong with my shoulder, and in under a month it started getting better. In less than a month my mobility came back, and after being stuck for so long, that is not a small thing. OmniStem wasn't just one more therapy. It was the place where the process finally started to work.
☆☆☆☆☆
If you are considering regenerative medicine, Omnistem has the highest quality and best sourced exosomes and stem cell therapy. They have their own state of the art lab on site, and provide fresh ( never frozen) tissue. Thank you to Northon and Amadeo and the whole Omni Stem team for taking great care of me!
☆☆☆☆☆
As a dedicated CrossFit athlete, I found Omnistem’s MSC treatment to provide a meaningful boost in both performance and injury prevention. The improvements in recovery and overall resilience have been noticeable. I would strongly recommend Omnistem to athletes looking to gain an edge in performance and recovery.
☆☆☆☆☆
I recently had treatment at OmniStem in the Dominican Republic, and I can’t say enough positive things. The entire staff was incredibly professional, thoughtful, and caring. The injections in my ankle for arthritis and pain have improved my mobility so much that I no longer feel pain when I run, no warm up or pain relievers needed for my ankles at all. I’m grateful to have received high quality stem cells intravenously knowing that the combination of regenerative therapies I received will support me in planning a successful second pregnancy. OmniStem truly delivered results that exceeded my expectations. Highly recommend!
☆☆☆☆☆
As a two time patient, I have nothing but positive things to say about the experience. Every time I leave, I feel amazing. The facilities are excellent and the staff is second to none!
☆☆☆☆☆
OmniStem was a complete joy from start to finish of my daughter's treatment. She has epilepsy and non-verbal autism, and a dear friend pointed us their way when we started looking outside the box for her. The procedure was just as smooth, having a translator in the room with us as well as the most amazing nursing staff you could imagine. I would highly recommend OmniStem to absolutely anyone seeking treatments that they offer. You will not be disappointed. We are forever grateful for the love, support and medical advancements of this beautiful company.

They go above and beyond to make sure everything is clearly explained. From the initial conversations to the follow-ups, you always feel cared for and supported.
My experience made me realize how important it is to take care of yourself from the inside out. Highly recommended 100/10!

I’ve noticed a massive improvement with my brain and how my body feels. I suffer from seizures and since I started my treatment I’ve been seizure free. There’s no words to describe how relieved I am to feel normal again. My memory and motor skills have also improved. I’m extremely grateful to Norton and his team.
