Your Healthcare clinic's phone rings at 9 PM. No one answers. That patient books with your competitor. Get a FREE demo AI voice agent (just shoot me a message). AI voice agents built on Vapi, Retell AI, and Synthflow answer every call — 24/7, in any language, routed directly into your booking system/CRMs (Hubspot/GoHighLevel). No missed calls. No lost revenue. No extra headcount. Most healthcare clients are live within 5 days. Awarded Top Rated on Upwork (Top 10%) with a Computer Science degree. One of the fastest-growing AI Automation, AI Voice Agent and Healthcare on the platform. 𝗧𝗛𝗘 𝗣𝗥𝗢𝗕𝗟𝗘𝗠 𝗪𝗜𝗧𝗛 𝗠𝗢𝗦𝗧 𝗛𝗘𝗔𝗟𝗧𝗛𝗖𝗔𝗥𝗘 𝗩𝗢𝗜𝗖𝗘 𝗔𝗜: Most AI voice agents are built by automation freelancers who've never touched an EHR and treat HIPAA compliance as a checkbox rather than an architecture decision. I build differently. HIPAA-aware architecture, PHI minimization, audit logging, and medical-escalation rules baked into every conversation flow from day one. The AI never diagnoses. It books, qualifies, and routes cleanly into your real systems. 𝗥𝗘𝗖𝗘𝗡𝗧 𝗥𝗘𝗦𝗨𝗟𝗧𝗦: — Dental network: Retell AI receptionist handling 100% of after-hours inbound. Appointment booking up 38%, front desk workload down 40%. — Miami primary care: Bilingual (EN/ES) Vapi voice agent with EHR and GoHighLevel CRM automation. Zero missed calls after hours. Live in 6 days. — UK healthcare staffing: 24/7 Synthflow shift-coordination agent with Twilio VoIP and n8n automation. Manual coordination reduced 70%. — 12-location chiropractic group: AI receptionist integrated into EMR and Google Calendar. First appointment booked within 3 hours of going live. 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗: 𝗛𝗜𝗣𝗔𝗔-𝗖𝗼𝗺𝗽𝗹𝗶𝗮𝗻𝘁 𝗔𝗜 𝗩𝗼𝗶𝗰𝗲 𝗔𝗴𝗲𝗻𝘁𝘀:Inbound and outbound voice agents on Vapi, Retell AI, and Synthflow wired into Twilio VoIP with HIPAA-aware architecture, PHI minimization, audit logging, and medical-escalation routing built in by default. 𝗔𝗽𝗽𝗼𝗶𝗻𝘁𝗺𝗲𝗻𝘁 𝗕𝗼𝗼𝗸𝗶𝗻𝗴 𝗮𝗻𝗱 𝗘𝗛𝗥 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻:* Voice agents that complete bookings inside your EHR, EMR, or scheduling system in real time using GoHighLevel, HubSpot, PracticeQ, Google Calendar, and custom API integrations handled end to end. 𝗕𝗶𝗹𝗶𝗻𝗴𝘂𝗮𝗹 𝗔𝗜 𝗥𝗲𝗰𝗲𝗽𝘁𝗶𝗼𝗻𝗶𝘀𝘁𝘀:English/Spanish bilingual voice agents handling patient intake, appointment booking, FAQ, and after-hours reception — so your front desk focuses on patients already in the room. 𝗥𝗔𝗚 𝗞𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲 𝗔𝗴𝗲𝗻𝘁𝘀:AI voice agents backed by RAG pipelines and vector databases pulling from your clinic documents and treatment protocols accurate answers without your staff lifting a finger. 𝗖𝗥𝗠 𝗮𝗻𝗱 𝗔𝗜 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻: Full backend automation on n8n and Make connecting your voice agent to GoHighLevel, HubSpot, and EHR systems, every patient interaction creates a record, triggers follow-up, and enters your revenue pipeline automatically. 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗛𝗲𝗮𝗹𝘁𝗵𝗰𝗮𝗿𝗲 𝗔𝗽𝗽𝘀: Patient portals, intake flows, and internal dashboards built with Next.js, Node.js, and Supabase when off-the-shelf tools aren't enough, HIPAA-compliant data handling throughout. 𝗪𝗛𝗢 𝗧𝗛𝗜𝗦 𝗜𝗦 𝗙𝗢𝗥: Dental clinics, medical practices, chiropractic networks, urgent care centers, and healthcare staffing agencies losing patients to missed calls, slow follow-up, or front desk overload. If your phone rings after hours and no one answers, you are paying your competitor's rent. 𝗧𝗘𝗖𝗛 𝗦𝗧𝗔𝗖𝗞 𝗩𝗼𝗶𝗰𝗲 𝗔𝗜: Vapi · Retell AI · Synthflow · ElevenLabs · Twilio VoIP 𝗔𝗜 𝗮𝗻𝗱 𝗟𝗟𝗠: OpenAI GPT-4o · Claude · LangChain · RAG · vector databases 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻: n8n · Make · Zapier · REST API and webhook integrations 𝗖𝗥𝗠 𝗮𝗻𝗱 𝗘𝗛𝗥: GoHighLevel · HubSpot · PracticeQ · Google Calendar · custom EMR integration 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸: Next.js · Node.js · Supabase · PostgreSQL 𝗖𝗼𝗺𝗽𝗹𝗶𝗮𝗻𝗰𝗲: HIPAA-aware architecture · PHI minimization · audit logging · medical escalation design 𝗚𝗘𝗧𝗧𝗜𝗡𝗚 𝗦𝗧𝗔𝗥𝗧𝗘𝗗: Message me with your call volume, booking system, and biggest gap; missed after-hours calls, slow follow-up, or front desk overload. I'll tell you exactly what I'd build, how long it takes, and the outcome you can expect before we agree to anything. Most healthcare AI voice agent deployments are live in 5 days. The first missed call your AI receptionist catches usually covers the cost.

I love call routing and scripting. With over 20 years experience I know how to make calls flow and how to create some pretty cool integrations with your CRM or any other app with an API. Five9 is the latest cloud phone system that I'm obsessed with. I've developed some out of the box IVR's and outbound drip campaigns that will increase your contact rate by 10% or more. Think of the Drips service but at no cost after implementation. Reach out with any questions you might have :)
