In this episode recorded at Longevity Fest 2025, host Dr. Lexi Gonzales is joined by Sunnita Mohanty, CEO of Ultralight (Formerly Vibrant Practice), and Crystal Brust, PA-C and founder of Farm to Functional Medicine. The conversation tackles the biggest barrier in the transition from "sick care" to longevity medicine: the overwhelming burden of documentation and data synthesis. The guests explore how AI-native platforms are not just automating tasks but acting as "full stack" solutions that restore the therapeutic partnership, increase clinical confidence, and even bring joy back to the practice of medicine.
Key Discussion Points
The Documentation Bottleneck: In functional medicine, the intake process involving timelines, matrices, and mapping is incredibly time-consuming, often forcing clinicians to choose between deep patient connection and high patient volume.
From "Stitched Together" to "Full Stack": Sunnita Mohanty explains the shift from using five or six disconnected legacy systems to an AI-native "full stack" platform (Ultralight- Formerly Vibrant Practice) that serves as both the core Electronic Health Record (EHR) and an intelligence layer.
The Therapeutic Partnership: Contrary to fears that technology creates distance, AI scribing allows clinicians to stop typing, maintain eye contact, and be fully present, which actually deepens the patient relationship.
Data Synthesis: AI enables clinicians to aggregate years of "dead documents" (old labs, PDFs) and complex genetic data into interactive, digestible summaries that would otherwise take weeks to process manually.
Clinician as Learner: The AI doesn't just summarize; it acts as a teaching tool, helping practitioners learn new correlations and genetic insights while they work through a chart.
Actionable Insights for Practitioners
Just Start Experimenting: If you are intimidated by AI, start by asking the same medical questions to different models (ChatGPT, Claude, Gemini) to understand their differences and get comfortable with the technology.
Audit Your Tech Stack: Look for platforms that integrate workflows rather than adding new silos. Moving to an AI-native EHR can consolidate faxing, messaging, prescribing, and ordering labs into one system.
Verify Before You Buy: As AI becomes a buzzword, "double click" into the details. Ask vendors about their security, compliance, and exactly how their product is built to ensure high reliability for patient health information.
Leverage Support for Transition: Don't let the fear of migrating data paralyze you. Modern "FHIR" standards make moving records easier than in the past, and platforms often provide human support teams to ensure you aren't "left on an island" during the switch.

Analogies for Understanding
"Iron Man" (The Heads-Up Display): Crystal Brust compares using the Ultralight platform to being Iron Man. Instead of digging through files, she has "panels of all this information" specific to the patient right in front of her, enhancing her capabilities instantly.

Crystal Brust, PA-C, IFMCP, brings over 15 years of clinical experience and national certification through The Institute of Functional Medicine. Her career began in emergency medicine, where she worked as an EMT, paramedic, and flight paramedic with over 5,000 hours of frontline experience while completing her undergraduate studies at Chico State. She later graduated from Stanford University’s Physician Assistant program and spent two years in pediatric cardiovascular surgery. After being diagnosed with polycystic ovary syndrome (PCOS) and facing fertility challenges, Crystal turned to functional medicine, finding meaningful healing through targeted lifestyle and nutrition strategies. This experience reshaped her clinical approach and deepened her commitment to root-cause care. She remains dedicated to ongoing education and helping patients achieve sustainable, whole-person health.
