Integrative and transformational Psychiatry .

Thorough. Targeted. Expert. Respectful. Flexible.

This is the standard we all deserve

What do we mean by ‘integrated psychiatry’: we don’t see you as a bunch of symptoms. We provide attentive holding of your whole personhood.

And for ‘Transformational’? We go way beyond symptoms to the core of what holds you back, keeps you stuck. We aim to rekindle your flourishing so you can be all you are supposed to be. This is what we mean, what we live and what we teach.

We are three clinicians united by a dedication to the deepest transformational potential for our patients (and, well in Mark and Danielle’s case, a longstanding marriage). We approach every patient with a deliberate, layered formulation. Before we recommend anything, we want to understand your hopes, strengths, and obstacles clearly. We gather your medications and how you've responded to them, your history with drugs and alcohol, sleep and diet, relationships and family system, your sense of purpose, and the emotional and behavioral patterns that run through and drive all of it. We integrate this all and - together with you - formulate a targeted and manageable plan.

Who We Are

decoration

Caring, courageous, and committed.

We are Mark Green, MD, Danielle Green, LICSW and Drew Welch, RN.

Between us, we bring expertise across psychiatry and psychopharmacology, depth psychotherapy, family therapy, addictions treatment, and psychedelic-assisted care.

We know that real change happens when you go deep into the emotions you learned to avoid. There may be pain and fear there, but we will be there with you every step of the way: guiding, advocating, championing. 

While we work independently most of the time, we also work collaboratively together - for example, psychopharmacology and therapy for one with Mark and family therapy with Drew - so you can learn all you need to make it out the other side, healed, wise and safe.

  • "Unambiguously profound impact on my life."

    "You have had an immeasurable, yet unambiguously profound impact on my life and I will never forget the way you have made me feel and the lessons I’ve learned. I know I am not alone in that regard."

  • “What you've created here is really special and unique."

    "I've been in therapies for 16 years but the progress I've made since I started here is remarkable… the combination of your therapy - which goes so much deeper than any other I've had - with the medication changes - they've all come together... I cannot say how fortunate I feel to have found you all.”

  • “You have the greatest integrity and skill that is rare in our line of work."

    "You are an exceptional clinician and a good human!”

Too often, therapy can feel like venting.

That’s all well and good, but you can get that from anyone for free. You deserve help with all that is getting in your way, even when that is hard to hear.

  • Healing the core issues, not superficial tweaks.

  • Deep therapy to rewire emotions and memories.

  • Time-limited treatment with clear goals, focus, and measured progress.

  • Lasting change from even the most entrenched stuckness.

With us, you experience:

  • Commitment. If you’re in, we’re in. If you’re not, it’s our job to motivate change. If you waiver or stumble we’ve got you.

  • Dedication to evidence-based practice and the latest advances in science..

  • But never sacrificing the heart.

“The longer I live, the more deeply I learn that love—whether we call it friendship or family or romance—is the work of mirroring and magnifying each other’s light. 

Gentle work. Steadfast work. Life-saving work in those moments when life and shame and sorrow occlude our own light from our view, but there is still a clear-eyed loving person to beam it back. In our best moments, we are that person for another.”
