Integrative Psychiatry & Ketamine-Assisted Therapy in Nashville, TN
Trauma-informed care for adults and late teens – in person at MindStream Integrative Medicine and via telehealth across Tennessee
I'm Lindy Porritt – a Vanderbilt-trained psychiatric mental health nurse practitioner. A lot of my patients have already put in the effort before we meet. They've tried medications. They've done therapy. Some are still functional on the outside but exhausted on the inside. Others are carrying something heavy and need someone who'll actually slow down with them. What I offer is the time, the testing, and the tools – including ketamine-assisted psychotherapy when it's the right fit – to help you move forward.
Who I Work With
Mood Disorders
You've tried various medications but experienced more side effects than real benefit. Some helped your symptoms but limited your joy. If this sounds familiar, you aren't alone. I work with adults who haven't responded to standard of care treatments, including those exploring ketamine-assisted psychotherapy.
Adult ADHD & Burnout
Many of my patients with ADHD didn't get diagnosed in childhood. They built coping strategies that got them to where they are now – and in their late 20s, 30s, and 40s, they're ready to understand themselves more fully and do things differently. I offer comprehensive evaluation, stimulant and non-stimulant options, and the lifestyle and nervous-system work that helps us optimize the treatment plan that fits your needs.
Trauma & PTSD
Anxiety, trauma, and PTSD live in the body, not just in thoughts. Treatment that addresses both is meaningfully more effective. As a trauma-informed PMHNP, I combine evidence-based medication, psychotherapy, and – for the right patient – ketamine-assisted psychotherapy that can complement trauma processing in safe, structured sessions.
How I'm Different
Longer visits, real conversations
45-minute initial visits and intentional follow-ups. I want to listen to what you need and support you in building a plan that puts you in charge of your own health.
Functional and metabolic testing
Thyroid, hormones, nutrient status, inflammation, gut health – the biology that often drives mental-health symptoms but rarely gets investigated.
Ketamine-assisted psychotherapy for treatment-resistant cases
Offered as an intramuscular or intravenous injection in the office, with a trained therapist present for the duration of the session. An integration session follows – giving you the space to process what came up and build on it as part of your ongoing healing.
Medication management and tapering
Whether you need to start a medication or come off one safely, I support both directions with the same care. Slow, intentional, and tailored to your individual pace.
