I'm Johnny Tock, Director of Global Business Development at J. Flowers Health Institute. I work with families and referral partners to connect individuals with comprehensive diagnostic and wellness services.

At J. Flowers, we specialize in getting to the root of complex situations — cases where mental health, medical, and substance use factors overlap and no one has the full picture yet. Our Comprehensive Diagnostic Evaluation brings medical, psychiatric, psychological, and neuropsychological testing together over 10–14 days, including brain mapping and rapid access to more than 100 specialists across the Texas Medical Center — appointments that would normally take months happen in days. Clients stay at The Houstonian, a five-star hotel and resort, with a dedicated wellness coach in the adjoining room throughout. It's hospital-level care that never feels like a hospital.

Whether you're a family seeking answers or a professional supporting a client, I'm here to guide you through the process with care every step of the way.

Take the first step toward clarity and compassionate care.

For Referring Professionals

How Referrals Work

Step One

Reach out

Email me, book a call, or send a text — whatever's easiest. Every conversation is confidential.

Step Two

We talk it through

I'll respond personally and we'll see if J. Flowers is the right fit. If it's not, I'll point you somewhere that is.

Step Three

You stay in the loop

I connect you with Allyson, our Director of Admissions. With your client's release, our team keeps you informed through to the final findings. Your client stays your client.

Not sure if a case is the right fit? That's exactly the kind of conversation I'm here for.

Find a time to talk
Based in Europe and working across US and European time zones, I partner with families and professionals in the US, Canada, the UK, and beyond.
