Dr. Weiss and his staff were absolutely amazing, kind and understanding. I haven’t seen any improvements with my son, that I was hoping for. But we are going to do another treatment at the end of the year and hope for the best.Posted on Google AyeshaTrustindex verifies that the original source of the review is Google. My son Elias has stem cell done at the clinic April 2023 , so it’s been awhile and now I can tell u exactly how his process or lack of it. First of all the staff and Dr. Weiss are absolutely amazing wonderful . Second the whole procedure took an hour from the time we entered the clinic til we left . It was pain free at least that’s what I thought until my son Elias 7 years old and nonverbal autism said his first word after the procedure “pain” I felt sad for his pain and happy for his first real word . He has improved dramatically since then he talks a lot even sentences , his eye contact is amazing he can read and write so much more then I can write I have recommended Dr Weiss to many of the friends they have seem their kids improve all, one of my friends brought two kids tether have been thriving . I’m differently coming back just the cost is too much for my family right now . I hope this helps any mom or dad considering this for their children. It does help and Dr Weiss is great .Posted on Google Amanda CataniaTrustindex verifies that the original source of the review is Google. Dr.Weiss and his team were absolutely wonderful! It was a wonderful experience. Can’t wait to go back for more stem cells. My son is doing great. Praying for progress.Posted on Google John Peregoy IIITrustindex verifies that the original source of the review is Google. We took our son to see Dr. Weiss and his staff just over a month ago for stem cell treatment. Dr. Weiss was very responsive to our questions during the consultation, although we didn’t have a lot of questions during to his social media presence. He has lots of information and his website and other social media platforms such as TikTok and Youtube. I highly recommend any parent to watch some of his interviews on YouTube before having a consultation call with him so you can educate yourself. Dr. Weiss and his staff treated our son like he was their own during the treatment. I could see the care for his wellbeing during the treatment and that gave us affirmation for making the correct choice to see Dr. Weiss. I believe Dr. Weiss will be the face of stem cell treatment for children with autism. We plan on going back for a 2nd treatment, if needed.Posted on Google Andy-Michelle BreretonTrustindex verifies that the original source of the review is Google. Dr Weiss and the entire staff are first class. They listen and answer any questions. They understand how stressful and worrying procedure can be. They treated our son and family with kindness and understanding. The procedure was so straightforward. The day after the stem cells our son went to a water park for the first time. He tolerated everything which he has never done. We couldn’t get him off the slide, he loved it so much. He held his sisters hand for the first time. He is approximating words so much more. This is just the start, we will be back. Stem cells are the futurePosted on Google Mesa WhitehurstTrustindex verifies that the original source of the review is Google. Dr. Weiss and team were great. There isn't a lot of clear information on "real" stem cells. I got treated with stem cells to recover faster from a radical prostatectomy (prostate removal). I had these stems cells done via IV (3.5 vials). Only time will tell as nerves take a long time to heal. I also had a 1/2 vial injected directly into my knee as I had (old man knee...I'm 48) and within two weeks my knee felt way better and now six weeks post injection I have no pain / swelling. Dr. Weiss is in it for the right reasons and I absolutely recommend him.Posted on Google Emily RaybouldTrustindex verifies that the original source of the review is Google. We went to see Dr. Weiss and his team in early November 2024. We have tried everything under the sun it seems like to help our 3 year old daughter. We absolutely saw changes in December and January. Cali has been parroting a lot of what we say and ask her to say, her speech is much more clear than before. The overall process was extremely easy and we plan to do another round in the future!Posted on Google Richie HaikTrustindex verifies that the original source of the review is Google. Our 7 year old son is nonverbal, level 3 autistic. We went to Dr. Weiss about one month ago for the stem cell therapy. Everything went very smoothly and Dr. Weiss was kind and made sure we had all questions answered. We never felt rushed and it went well. We saw a slight uptick in emotional behavior shortly after the treatment. Just some crying and sadness at times when he didn’t get his way. He also didn’t sleep well for a few weeks after. But that’s seemingly over now and we’ve seen an increase in verbalization and sounds—no words yet really but many more sounds and made with intention. He’s also been engaging much more with his sister and even playing some with her. He’s been extremely happy and we attribute a lot of the increased “good” behaviors to the stem cells. Time will tell on the long term gains, but we’re very happy with our decision to get the therapy here.Posted on Google Summer SuzieTrustindex verifies that the original source of the review is Google. I’d like to share that since receiving Stem Cell Therapy with Doctor Weiss we have seen significant improvements in our Autistic son. He is more calm and responsive than he was before and we can’t thank this team enough for what they’ve done for our family. They were ready and prepared from the second we walked in the door, everyone from the front desk to the nursing staff were incredibly supportive, kind and patient with us. I will be going back again for additional treatments. I have told everyone I know about this office with the hopes other families can experience what we have.Posted on Google Lita PoehlmanTrustindex verifies that the original source of the review is Google. I'm 83 and have dealt with numerous health issues and chronic pain for years. I'm a month out from stem cell treatment and remain hopeful that I will see a significant reduction in pain over time. Future lab results will reveal changes regarding autoimmune issues. I'm sleeping better and have more energy than I've had in ages.
Request a consultation to discuss any questions for you or for you child.
The entire process is relatively quick and straightforward. The IV infusion of umbilical cord blood stem cells typically takes about 30 to 45 minutes. Patients are observed briefly afterward to ensure they are stable and comfortable.
The stem cells are delivered through a simple intravenous (IV) infusion. This method allows the cells to circulate throughout the body and target areas of inflammation or injury. The cord blood is shipped frozen from a trusted FDA-compliant facility, and arrives on dry ice. It is carefully thawed and infused within minutes to ensure maximum cell viability. Because it is a transplant of living tissue, strict handling and timing protocols are followed.
The stem cell infusion is a straightforward outpatient procedure that typically takes about one hour. Once the IV line is securely placed, a saline solution is administered while the umbilical cord stem cells are gently brought to room temperature — a process that takes a few minutes. The stem cells are then administered through the IV in a single infusion. For certain conditions, such as arthritis, direct joint injections may also be an option, which can be discussed with Dr. Weiss.
For pediatric patients or others who may be anxious about the IV placement, sedation is available at no additional cost. The most commonly used medications are Ketamine and/or Versed (Midazolam), administered via a quick intramuscular injection. These medications have excellent safety profiles and provide both sedative and amnestic effects, helping make the experience smoother and less distressing for children and families alike. Dr. Weiss will discuss all options with you during your consultation to ensure your child’s comfort and safety throughout the process.
Most patients tolerate stem cell treatment very well. According to current data, approximately 97% of patients experience no adverse reactions. A small percentage may experience mild, temporary side effects such as headache, fatigue, rash, low-grade fever, upset stomach, flu-like symptoms, or minor discomfort at the injection site. In a small percentage of children with autism, a temporary increase in hyperactivity or transient aggressive behavior may occur following treatment. This typically resolves within 2 to 12 weeks, returning to baseline—and in most cases, leading to noticeable improvement beyond the initial behavior. Dr. Weiss and his team will monitor you closely to ensure safety and comfort throughout the process.
Many patients begin to experience noticeable improvements within 10 to 14 days following treatment. In many cases, the benefits continue to build gradually over the following weeks to months, as the stem cells continue their regenerative and anti-inflammatory effects within the body. It’s important to note that individual results can vary, and Dr. Weiss will discuss expected outcomes based on your specific diagnosis and treatment goals.
The timing and need for additional treatment varies depending on your specific condition, the severity of symptoms, and your individual response to the initial infusion. Some patients may experience lasting benefits after just one treatment, while others—particularly those with chronic or progressive conditions—may require a series of treatments spaced out over time for optimal results. During your consultation, Dr. Weiss will evaluate your medical history and therapeutic goals to help determine the best course of action.
Yes, certain medications can interfere with the effectiveness of stem cell therapy and should be paused before treatment. Patients are advised to stop taking non-steroidal anti-inflammatory drugs (NSAIDs)—such as ibuprofen, naproxen, or aspirin—at least one week prior to the infusion, as these medications can suppress the body’s natural healing and inflammatory response that stem cells rely on to function optimally.
Additionally, steroid medications (such as prednisone) and arthritis medications (DMARDs) like Enbrel, Humira, or similar agents should be discontinued at least two weeks before treatment, unless otherwise directed by your physician. These drugs can impair immune signaling and reduce the therapeutic activity of the infused stem cells.
After the infusion, it’s important to continue avoiding these same medications for a period of time—two to four weeks—so that the stem cells can integrate, migrate, and begin their regenerative work without interference. Please consult with Dr. Weiss prior to treatment for specific medication guidelines based on your condition and current prescriptions.
Stem cell treatment is not recommended for individuals with active cancer or infections. These conditions can interfere with the safety and effectiveness of the therapy
Yes, you can resume normal daily activities shortly after treatment. We encourage maintaining an active lifestyle, including regular exercise and therapy.
Many parents ask if they can use the cord blood or tissue they personally banked at birth for their child’s treatment. While this is your own stored biological material, unfortunately, we are currently unable to use banked umbilical cord blood or tissue for stem cell therapy.
Most private cord blood banks will not release stored cells for conditions like autism, as this use is not FDA-approved. For safety and compliance reasons, our treatments must use stem cells from FDA-regulated, rigorously screened donor sources.
We understand how important this option may be to families, and we will continue to monitor regulatory developments. If it becomes feasible and safe to use banked cells in the future, we will do our best to make it available.
