Quantum's Evolution

Quantum emerged as a visionary response to the urgent need for culturally competent mental health services, particularly for marginalized and underserved communities. Founded on the principles of empathy, inclusivity, and empowerment, Quantum has grown into a beacon of hope, offering a wide range of mental health services that honor the diverse experiences of its clients. The organization's commitment to understanding and addressing the unique challenges faced by various communities has been at the heart of its approach, making it a trusted and respected entity in the field of mental health. Building on this foundation, Quantum created Project THRIVE, an initiative specifically designed to address the complex mental health needs of communities often left behind by mainstream services. Project THRIVE represents a bold step forward in providing comprehensive, culturally affirming care. It aims to empower individuals through innovative programs and therapies, fostering resilience, wellness, and personal growth. The project's holistic approach integrates evidence-based practices with an understanding of the socio-cultural dynamics affecting mental health. Through Project THRIVE, Quantum is not only offering essential services but also advocating for broader change in how mental health care is understood and delivered, particularly to those who have historically been marginalized.

Martha, from Texas
"Quantum Consulting Group has been a beacon of hope in my life. As a Latina and a proud member of the LGBTQ+ community, finding a place that understands and respects my identity has been a challenge. Quantum didn’t just offer services; they offered a safe space where I felt seen and valued. Their culturally affirming approach made a huge difference, allowing me to embrace my true self without fear. The support and guidance I received here have empowered me to make positive changes in my life and in my community."

Aaliyah, from Missouri
"Quantum Consulting Group truly stands out for its dedication to serving black and brown communities. As a young African American woman entering the professional world, I faced many obstacles. Quantum’s mentorship and resources helped me navigate these challenges with confidence. Their focus on inclusivity and cultural affirmation resonates deeply with me. They are not just changing lives; they are shaping futures. My experience with Quantum has been transformative, and I am grateful for their unwavering support and commitment to diversity and empowerment."


Kevin, from D.C.
"I started seeing Dr. Cal at Quantum the summer of the pandemic. When I came to Dr. Cal I had already experienced a wealth of disappointment. I was severely depressed and had been for a while. Our sessions always started with roses and thorns. I probably had more thorns than roses. Thus, I was always in a dour mood. Nothing seemed to be going right. In fact, during this time I found myself really only anger twice within 6 months of our sessions. When I let it go, it was because of Dr. Cal who had spent a great deal of time coaching and teaching me to deal with and handle my feelings as I had put them away for the sake of others. Fast forward to late winter 2022. As I walk through my home, I realized it was no longer a safe place. It was filled with anxiety and stress. It was then I realized it was really ok to think about me and my needs and what the future looks like. I was finally able to make sound decisions for myself and my life moving forward. Through all of my sessions with Dr. Cal’s help, here I am today happy with life and excited about my future. Through the vision boards I have made during our time. The self-help books I’ve read. The exercises I learned to use with Dr. Cal’s help have helped me become a better person for myself. I now advocate for myself in areas I always found stifling. I will end on the note. I was at a planning dinner with 7 friends. We all laughed throughout the evening. Then one friend says, “I’m not sure who the Kevin was I met two years ago, but I absolutely love this Kevin.” This process has been the most fulfilling and life changing."

Kelvin, from Missouri"
Dealing with the pressures of college life and the societal challenges of being a young Black man was taking a toll on my mental health. Therapy at Quantum Consulting Group was a turning point. It provided me with the tools to cope with anxiety and stress, and to build a positive outlook on life. The therapists here are not only skilled but also genuinely care about representing and understanding diverse backgrounds. I'm now more confident and optimistic about my future, thanks to the support and guidance from Quantum."

Evolving, St. Louis 
"Before finding Quantum I didn’t believe in therapy. I had numerous therapists in the past who helped me obtain the resources needed to support my gender transition, but none who truly understood me. Until I met Dr. Cal, not only did he share similar lived experiences but has truly helped me in my healing journey and proud to say that his work saved my life. I am forever grateful to have found a therapist/healer that is honest, supportive, realistic, and keeps me accountable on my healing journey. I always recommend anyone I know that is seeking healing to Quantum because I know the quality of therapy I have received, I don’t know a better place."

Tasha, from Illinois
"As an African American single mother, I faced challenges that seemed insurmountable. The therapy I received at Quantum Consulting Group was life-changing. It was a space where I felt heard and understood. The strategies and support I got helped me manage stress, build resilience, and become a more confident parent. My therapist's culturally affirming approach made all the difference, making me feel empowered in my identity. Quantum's therapy services have not only helped me but also positively impacted my children's lives."

Carlos, from Texas
"Before I started therapy at Quantum Consulting Group, I struggled with accepting my identity as a Hispanic gay man. The cultural pressures and personal doubts were overwhelming. But the therapy sessions here changed everything. My therapist, who was culturally sensitive and deeply understanding, helped me navigate through my fears and insecurities. I've learned to embrace who I am, find strength in my identity, and live a life true to myself. Quantum didn't just offer therapy; they offered a path to self-discovery and acceptance."
