This is an update to my September 1st review. I finished all treatment weeks ago and have to say,…read moremy results have remained stable and fantastic. Everything shared in my original review is still true, albeit I still struggle a little with my eating self-discipline (not Sleep Recovery's fault, mind you ... ) In my experience, there was never any pressure sales. In fact, on the SleepRecoveryUSA.com website, there was an introductory offer of $500 for 4 sessions so if it doesn't work, a person doesn't have to purchase the entire program. I had positive results before session 4, so of course I continued and was so glad I did. :) One negative reviewer questioned "the authenticity of any positive reviews". Sorry, but that's a little insulting to those who took the time to support a business on Yelp. Let's agree to disagree politely, shall we? smh.... Thank you again David and SleepRecoveryUSA.com

When I first met with David, I felt seen and validated. I trusted the process fully. He asked me…read morenot to look up side effects before I committed to the treatment by paying the fee, so that my anxiety would not interfere. This seemed reasonable at the time, and I personally believe that David had good intentions. After I paid, I recall the conversation leaving me with the understanding that there weren't any side effects I needed to be concerned about. I am not saying he was intentionally dishonest, but I wish I had researched them myself. I developed severe side effects, including uncontrollable physical and cognitive anxiety, extreme daytime sleepiness, and altered visual perception. When I told David, he dismissed and invalidated my concerns, insisting that the symptoms had nothing to do with the treatment. When I asked why he had not informed me about possible side effects, he questioned why I hadn't looked up possible side effects myself and implied that it was my responsibility to do so. That response was profoundly unethical. As a mental health provider, it is his responsibility to disclose potential side effects, not the client's responsibility to guess them. Although neurofeedback is often advertised as non-invasive and side-effect-free, research shows that it can cause significant side effects. Neurofeedback changes brain function. Even if no current is being sent into the brain, the algorithm reinforces some brainwave states while discouraging others, which reshapes how the nervous system regulates itself. Side effects can include worsened anxiety, agitation, mood changes, and disrupted sleep because the brain is being trained away from its natural rhythms. This affects the entire body, as brainwave patterns influence the autonomic nervous system, hormones, and sleep cycles. Any provider who claims a treatment can significantly change brain function for the better but refuses to acknowledge that it can also cause harm is not appropriately trained in the science behind psychological treatments. My side effects left me terrified that my brain had been permanently altered, and I was left to face that alone. David refused to answer further questions until I mailed back the equipment, simply because I had expressed that I was upset. I returned it immediately and never intended to withhold it. Over time, I became suicidal due to the severity of the side effects. I want to be clear that I am not saying David caused me to feel suicidal. However, he failed to fulfill his ethical duty of care and did not show empathy or accountability when I was in distress. When I later consulted licensed neurofeedback doctors, they confirmed that I was experiencing acute side effects from the treatment. After three months and intensive mental health care, my symptoms began to fade, and I am doing well now. This was a traumatic experience, not because neurofeedback itself is inherently harmful, but because of the lack of transparency and support I received on top of the strength of the side effects I was experiencing. David may have followed the technical steps correctly, but he failed to inform me of the risks and treated me with deep disrespect once I raised concerns. If you decide to pursue neurofeedback, please research thoroughly and choose a provider who will treat you with respect, transparency, and empathy and who will openly discuss both benefits and risks.

After my initial phone call to the Riverside, and then days later sending an email to them, I received a call from Terry at the Irvine location. Terry immediately addressed my concerns I put in the email. He also alerted me that I was misinformed my the Riverside location, about not being able to self-refer when I have PPO insurance. My husband was/is going through a medical emergency and I was attempting to establish care and an appointment for him to get checked out. If it was not for Terry being thorough/detailed, proactively securing my husband's medical records by me answering a couple of questions, overall kind, attentive, and we would not have gotten in to see a doctor until the following week. We were booked next day, with Terry's help. As a result, I opted to make the drive from the IE to Irvine, instead of the Riverside location the very next day. Good medical practices are very hard to find these days. Terry actions demonstrated compassion and understanding of my concerns of not having my husband wait any longer for an examination. Thank you Terry! Additionally, our appointment was for 12pm. The doctor was prompt and thorough as well. The receptionist that check us in was also prompt, thorough, she showed concern when it appeared that my husband's oxygen was a tad bit low. Said for him to relax, lay back in the recliner and she would get the doctor in right away. I sincerely appreciate the team here. I'm glad Terry called. Thanks you to everyone we encountered last week.
