I’ve had an excellent experience with Mentis Institute! Catalina is incredibly professional, yet gentle and attentive to her clients' needs. She takes the time to explain in detail how the neurofeedback process works, including which areas of the brain are best to train based on my personal needs and goals. This thoughtful approach helped me feel confident and informed throughout the journey. The brain mapping process is fascinating—it’s amazing to see the clear before-and-after results, which provide tangible evidence of progress. The training apps Catalina uses are interactive and engaging, making the sessions both effective and enjoyable. After just three months of training, I’ve noticed significant improvements in my mood and mental clarity. My thoughts feel more organized, I’ve stopped overthinking and creating scenarios in my head, and I feel much calmer and more focused on my daily tasks. I highly recommend Mentis Institute to anyone considering neurofeedback—it’s been life-changing for me.

Die Arbeit bei Catalina hat für mich eine völlig neue Dimension eröffnet. Durch das Loslassen, wie ich es im Qi Gong gelernt habe, geschieht alles auf natürliche Weise. Seit ich regelmäßig an den Sitzungen teilnehme und das entspannte „Nichtstun“ übe (oder eben nicht :)) bemerke ich bereits nach der ersten Sitzung Veränderungen: Ich kann mich länger auf ein Thema oder eine Aufgabe konzentrieren, ohne mich ablenken zu lassen. Bei meiner Arbeit, die viele parallele Aufgaben umfasst, mache ich deutlich weniger Fehler und bin insgesamt entspannter. Ein interessanter und angenehmer Nebeneffekt ist, dass ich keinen Heißhunger mehr auf Süßes habe. Wenn ich doch einmal Lust auf etwas habe, wähle ich eine gesündere Alternative als zuvor. Mein ursprüngliches Ziel war es, meine Konzentration zu verbessern, und dieses Ziel habe ich nicht nur erreicht, sondern weit übertroffen. Es ist wirklich faszinierend und hat Parallelen zu meiner Meditationspraxis: das Yin, die Ruhe, zu navigieren und dennoch präsent zu bleiben – ohne einzuschlafen. Ich empfehle diese Therapie bei Catalina, mit ihrer fundierten Fachkenntnis, Begeisterung und Empathie wärmstens weiter.

I am impressed with how much neurofeedback has helped me. Before these sessions, my mind used to wander constantly, especially when trying to focus on a specific task. I’d start out with one idea and somehow end up deep in random thoughts or distractions. Now I can actually stay on topic! My concentration has improved noticeably, and I’m not fighting to keep my brain on track anymore. I feel way more present and engaged during conversations, tasks, and school assignments. It’s like my mind’s finally learning to do what I want it to do instead of running off in 20 different directions. Many thanks!

My mind is finally quiet. Before starting with neurofeedback and mental training, it felt like a pinball machine—whenever I closed my eyes, thoughts would come crashing in from every direction, bouncing around uncontrollably. It was exhausting.

It’s hard to describe the shift, but now, when I close my eyes, it’s no longer a chaotic rush of thoughts. Instead, it’s calm, peaceful, even pleasant. I actually enjoy being in my own head! Catalina not only guided me through neurofeedback but also helped me learn practical tools to stop engaging with the anxious thoughts that used to take over. I’ve gained so much more control over my mental space, and the difference is night and day.

My experience at Mentis Institute Switzerland has been truly transformative. The incredible Neurofeedback and Brain Training work I've been doing with Catalina has exceeded all my expectations. After some sessions, I've noticed significant improvements in the quality of my sleep. The restless nights and long hours trying to fall asleep have become increasingly rare. I've returned to having vivid dreams, full of colors and sounds, something I hadn't experienced since before my daughter's pregnancy. Now, I enjoy longer and deeper nights of sleep, which has positively impacted my overall well-being. Catalina's sweetness and professionalism make each session a pleasant and light experience. Her dedication and expertise are evident in every step of the process. I am deeply grateful to Catalina for the exceptional work she has done with me. I highly recommend her to anyone seeking to improve their mental performance and well-being.

As a busy executive, I'm always seeking efficient ways to optimize performance. Catalina's program delivered beyond expectations in just 17 sessions over two months. Key outcomes: resolved chronic insomnia (now consistently achieving 7+ hours of sleep), 30% improvement in overall life quality, and a 25% boost in work performance. The program's strength lies in its holistic approach - combining cutting-edge neurofeedback techniques with targeted coaching: cognitive & emotional resilience training methods, and strategic lifestyle adjustments. If you're a high-performing professional wanting to step up your game, Catalina's coaching and training program is an invaluable investment. It's more than just improvement, it can completely transform how you perform and excel.

With decades of experience behind me, I was curious about maintaining mental health and understanding how aging affects the brain. Mentis Neurofeedback Center in Zug exceeded all my expectations. The process was very insightful and professional. Ms. Sparleanu took the time to explain the brain mapping process (qEEG) in a way that was both comprehensive and easy to understand. She carefully walked me through each step, addressing all my concerns. The session was fascinating. I received insightful explanations about how different areas of my brain perform, particularly concerning my age group. The discussion afterward was thorough and encouraging, outlining actionable steps I can take for mental training and long-term brain health. Highly recommended for anyone who wants to take better care of themselves and improve their performance. I’m reminded that the mind, like a muscle, can benefit from the right exercises and the right guidance. With my insights, I will now focus on training my brain muscle.

I have been feeling restless and anxious for a while, so I decided to visit MENTIS for a brain mapping (qEEG) session. The experience was fantastic, smooth and professional, but also very welcoming. The brain map results were so eye-opening and captured exactly what I had been going through. I really appreciated how easy it was to communicate and how comfortable the whole process felt. I left the session feeling more aware of what might be contributing to my challenges and with a better understanding of potential solutions. If you’ve been feeling anxious, restless, or emotionally overwhelmed, I highly recommend giving this a try—it’s a real eye-opener!

As an Oberstufe student, my experience at Mentis Institute has been incredibly positive and enjoyable. Before I started, I struggled a lot with anxiety and often felt down without really understanding why. My thoughts would constantly overwhelm me, and I found it difficult to make sense of what I was feeling. I also had trouble sleeping, which made everything even harder.

From the very first session, Catalina made a huge difference. She is extremely welcoming, kind, and easy to talk to. I felt comfortable with her immediately. She creates such a safe and trusting environment that you naturally feel like telling her everything. No matter what I wanted to talk about, she always listened carefully and never made me feel judged.

After only a few months of neurofeedback training, I already started noticing significant improvements. I was sleeping much better, feeling less anxious overall, and my mood improved noticeably. I also became much more confident in situations that used to make me nervous, especially speaking in front of other people. On top of that, my grades started improving as I was able to focus better without feeling anxious before or during a test.

One thing I really enjoyed about neurofeedback was how interesting it was to learn more about how my brain works. The training sessions are also surprisingly entertaining, with games and movies that make the process enjoyable rather than feeling like a treatment.

Overall, I am extremely grateful for the support I received at Mentis Institute, especially from Catalina. The progress I have made in such a relatively short time has been amazing, and I would highly recommend Mentis Institute to anyone who is struggling with anxiety, sleep issues, or simply wants to better understand and improve their mental well-being.

I came across Catalina's services by accident online and decided to try the neurofeedback sessions for my children. I must admit I rarely come across such a competent and thorough professional like Catalina. Before starting the sessions, she conducted evaluations, walked us through the results individually, to make sure everyone is comfortable to ask questions, and provided detailed session summary and feedback after every session. She also provided her perspective and advice, which I really appreciated.

Ich bin unglaublich dankbar, Frau Sparleanu und das Mentis Institute gefunden zu haben. Von Anfang an hat sie sich viel Zeit genommen, um meine individuellen Bedürfnisse und Herausforderungen wirklich zu verstehen. Ihre Kompetenz, ihr großes Fachwissen und ihre einfühlsame, respektvolle Art haben sofort Vertrauen geschaffen.

Durch ihre professionelle Neurofeedback-Behandlung habe ich es endlich geschafft, meine Schlafprobleme zu überwinden – ich schlafe jetzt regelmäßig acht Stunden und schlafe viel schneller ein. Besonders wertvoll war auch, dass sie mir nicht nur beim Schlaf geholfen hat, sondern gemeinsam mit mir weitere Themen erfolgreich angegangen ist.

Man spürt, dass sie ihre Arbeit mit echter Leidenschaft und großem Engagement macht. Sie arbeitet äußerst individuell und lösungsorientiert, was selten zu finden ist.

Ich kann Frau Sparleanu von ganzem Herzen jedem empfehlen, der Unterstützung sucht – sowohl Erwachsenen als auch Kindern, denn sie verfügt auch über große Erfahrung mit jungen Klienten. Eine absolute Expertin auf ihrem Gebiet!
