The Fishtown Medicine onboarding packet sets clear ground rules for new members. We use the Ultralight app for secure messaging, hold to strict clinical independence (no kickbacks, no product sales), and manage specialist coordination so you never have to be the middleman in your own care.
Welcome to Fishtown Medicine. To make our partnership effective and focused on your long-term health, we set clear, simple guidelines for how we work and how we communicate. This packet is meant to help you get the most out of your first 90 days.
How does Fishtown Medicine protect clinical independence?
My first priority is your health, independent of any commercial interests. Our Practice Constraints protect that promise.
- No Product Sales: We do not sell supplements or medications.
- No Kickbacks: We do not accept fees from pharma or device companies.
- Neutral Data: Recommendations come from your clinical data and current peer-reviewed research.
- Pass-Through Pricing: Any discount we receive from a partner - supplements, imaging, labs - passes straight through to you. We do not mark up partner pricing.
How do new members communicate with the clinic?
We use the Ultralight app for all clinical communication. The app is encrypted and HIPAA-compliant, which keeps your data safe.
Routine Needs
- In-App Messaging: Best for non-urgent clinical questions, care plan clarifications, or follow-up on labs.
- Response Time: We typically respond within one business day.
Urgent Needs
For an Urgent Need that cannot wait until the next business day:
- Direct Message: Use the Ultralight app and flag the message as urgent.
- Emergency Service: For life-threatening emergencies, dial 911 or go to the nearest emergency room (Penn, Jefferson, or Temple in Philadelphia).
How does the practice coordinate specialist care?
If you need a specialist, we manage the logistics for you:
- Curation: We find a high-quality specialist in Philadelphia for your specific condition.
- Clinical Briefing: We send a detailed summary of your history so the specialist is prepared for your first visit.
- Integration: We follow up to make sure their findings are integrated into your Personalized Care Plan.
