Meet The CJ3 Foundation from Albia, Iowa!

The CJ3 Foundation, founded by veteran Eric D. Thomas, is a 501(c)(3) nonprofit public charity dedicated to “Serving Our Nation’s Wounded Heroes.” CJ3 provides vital support, services, and advocacy for wounded and disabled U.S. Military Service Members, Veterans, Law Enforcement Officers, Firefighters, and Emergency/First Responders. Their mission is to help America’s heroes find the means and opportunities to holistically improve their quality of life and reconnect with the communities they so selflessly served.

Through their four primary initiatives—Advocacy, Mental Health & Wellness, Service Dogs, and Field Ops—CJ3 creates pathways for healing, restoration, and purpose. Whether it is providing trained service dogs, organizing outdoor activities that promote camaraderie and resilience, or guiding policy changes to support the needs of wounded heroes, every aspect of their work is driven by compassion and service.

At the heart of CJ3’s Mental Health & Wellness Initiative is a commitment to integrative care, and neurofeedback plays a pivotal role. CJ3 incorporates Infra-Low Frequency (ILF) Neurofeedback to help veterans and first responders recover from challenges related to their experiences in the field while supporting overall wellbeing. The Foundation also uses Alpha-Theta therapy, which supports relaxation and helps participants process intense experiences and memories. This program is operated under the guidance of Dr. Rebecca A. Thomas, PsyD, a licensed clinical psychologist and partner to the Foundation.

The Foundation has been using BEE Medic neurofeedback equipment since 2005. The team’s journey began in Norfolk, Virginia, when Lanny Fly, a pioneer in the field of neurofeedback, invited the Othmers to provide training, laying the foundation for their long-standing practice. Today, CJ3 operates two offices with Cygnet systems and maintains a full-time practice in rural Iowa, offering a variety of adjunctive therapies, with neurofeedback remaining the backbone of their success.

CJ3 also offers an all-expenses-paid five-day intensive retreat for up to four participants at a time. Guests stay in a restored historic Iowa home that once belonged to the 23rd Governor of Iowa. These immersive experiences combine neurofeedback with a range of holistic modalities, including chiropractic support, detoxification, and trauma-informed therapy, providing participants with tools to carry forward into their daily lives. Family-style meals foster connection, and participants progress through rounds of treatments to support their needs, including psychological evaluations focused on emotional wellbeing.

The impact of this work is profound. One veteran shared that after years of difficulty in crowded environments, he was able to travel home from his CJ3 intensive calm and confident. Another veteran’s wife expressed tearful gratitude, saying, “What have you done to my husband?" She went on to say that after many years of wanting to isolate, they were sitting outside at a restaurant and he was socializing with other folks.

For many participants, neurofeedback becomes a turning point when other approaches have fallen short. Many arrive stating, “I have a rucksack full of medication, but I still feel awful,” but leave with hope, connection, and lasting change. Beyond individual outcomes, the CJ3 Foundation helps restore what many veterans miss most—the brotherhood and sense of belonging that comes from shared experience and mutual support. Some participants are paired with service dogs that provide long-term assistance, extending the benefits of the Foundation’s programs well beyond the retreat.

Through the integration of neurofeedback and other holistic therapies, the CJ3 Foundation continues to honor its mission of helping America’s wounded heroes reclaim their strength, reconnect with their purpose, and rediscover joy in everyday life.

About CJ3 Foundation

The CJ3 Foundation’s commitment to healing our nation’s heroes is both personal and powerful providing life-changing programs that embody CJ3’s values: Combined, Joint, and Operations—a reflection of unity, teamwork, and coordinated care for those who have given so much.

In September 2025, the journal *pt – Zeitschrift für Physiotherapeuten* published an interview with Charlotte Wolf, physiotherapist, naturopath, and certified user of ILF Neurofeedback with BEE Medic devices. In the interview, she discusses how Neurofeedback can be meaningfully integrated into physiotherapy and the potential it offers for both patients and practitioners. In this blog post, we share the most important takeaways from the interview.

What is Neurofeedback?
Neurofeedback is a scientifically established form of brain training. It measures brain activity through electrodes and provides real-time feedback via subtle visual and auditory changes within a film, game, or animation. The brain starts to interact with the system and learns through the feedback to change its own activity. This process enhances self-regulation, which in turn can improve focus, stress tolerance, sleep quality, pain perception, and many other aspects of daily functioning as well as medical  indications.

When traditional physiotherapy reaches its limits
Manual and movement-based therapies are powerful tools but sometimes they are not enough on their own to achieve lasting relief from pain, tension, or neurological symptoms. Often, the underlying cause lies deeper, within the brain itself. That’s where Neurofeedback comes in. By training the brain’s ability to self-regulate, it supports and strengthens the physical work done in physiotherapy.

Why Neurofeedback and Physiotherapy are a powerful combination
In her daily practice, Charlotte Wolf observes the benefits first-hand:
“I use Neurofeedback as a supportive method when I notice that dysregulation in the brain is hindering progress or contributing to the symptoms.”
For patients dealing with muscle tension, migraines, chronic pain, or neurological conditions such as traumatic brain injury, stroke, Parkinson’s disease, CRPS (Morbus Sudeck), or fibromyalgia, the synergy between Neurofeedback and physiotherapy can make all the difference. While physiotherapy targets the body directly, Neurofeedback helps the central nervous system regain flexibility and balance — the foundation for sustainable physical change.

How the two methods work together
In Charlotte Wolf’s practice, Neurofeedback is incorporated in two main ways:
• As separate sessions during the week: one for physiotherapy, one for Neurofeedback.
• As a combined session: physical therapy followed by Neurofeedback (or vice versa), lasting about 90 minutes in total.
Patients often report improved relaxation, reduced pain, and heightened body awareness as a result.

Beyond therapy: Training for Peak Performance
Neurofeedback isn’t just for rehabilitation or symptom management. It’s also increasingly used in the field of performance optimization. Here, the focus shifts from treating dysfunction to enhancing mental clarity, concentration, and resilience under stress.

No Quick Fix – But Sustainable Change
Wolf emphasizes that Neurofeedback isn’t a substitute for other forms of therapy, nor is it a quick fix. It’s a learning process that requires time and consistency. The brain can’t simply be reprogrammed, it learns to regulate itself through repeated feedback and practice.
“Our brain isn’t a machine where you can just tighten a screw. But through regular training, it can find its way back to balance.”

Conclusion
Neurofeedback opens up a new dimension in physiotherapy. By extending physical treatment to include the neural level, it provides an effective approach for chronic and stress-related conditions, as well as for prevention and performance enhancement. For many patients, this combination paves the way toward greater well-being, functionality, and mental strength.
