Ascero AI builds custom voice agents and workflow automation for medical practices operating in the MetroWest Boston metro (64,000 residents, roughly 4,200 small businesses, ACS-derived median household income around $102,000). Founder-led, flat-fee Foundation tier at $4,000/month, BAA executed where required, live in two to four weeks depending on vertical.
Outpatient medical practices abandon an estimated 18 to 28% of inbound calls, per MGMA 2025 operational benchmarks — and abandoned calls drive patient leakage to urgent care, retail clinics, and competitor practices. The receptionist is checking in a patient, verifying insurance on another line, and the phone keeps ringing. The patient who got voicemail is on the MyChart app booking with a different practice. The Ascero AI receptionist for medical practices answers 24/7 under HIPAA-compliant BAA, books appointments into Epic / Cerner / athenahealth / eClinicalWorks / NextGen, triages prescription refills, verifies insurance eligibility, and routes clinical urgencies to the on-call nurse line. Every PHI interaction is logged, audited, and signed under a Business Associate Agreement.
what Waltham medical practices are leaving on the table
The MetroWest Boston metro has roughly 4,200 small businesses, a figure derived from US Census County Business Patterns and Business Dynamics Statistics at the MSA level. The dollar figures below are an illustrative worked example, not a measured Waltham statistic — they exist to make the math concrete, and every input is stated so you can swap in your own numbers.
Illustrative estimate — assumptions shown, not a measured figure
The agent does not need to be perfect — it needs to be better than voicemail. The per-business figures we actually stand behind, with sources, are below.
A 3-provider primary-care practice doing $2.4M in revenue, with 90 inbound calls per day, 22% abandonment, and a $180 average visit revenue: roughly 20 abandoned calls daily, of which 40% would have booked = $1,440/day or roughly $525K annually in recoverable visit revenue. Plus 4 to 6 nurse hours per day reclaimed from refill triage. Even at a 30% recovery rate, $158K back to the P&L on a $48K subscription.
the Waltham context
Ascero AI is headquartered here. Both co-founders live within 10 minutes of Moody Street. The MetroWest SMB base is bifurcated: Moody Street restaurants and Main Street retail, plus 128-corridor office-park firms (law, RIA, professional services) that operate B2B but still answer the phone themselves.
Ascero AI is founder-led from Waltham, Massachusetts. Both co-founders (Kadin Nestler and Jaiden Lawlor) build into customer calls directly — the discovery, prompt design, and tuning loop is run by the same people who close the deal. For Waltham medical practices that is meaningful because the phone-handling tuning that wins is vertical-and-region specific (a Waltham medical practices's ideal triage is not the same as a generic national template), and we ship those refinements monthly. US-based, no offshoring, no contract receptionist resellers — the people you talk to are the people building the agent.
Pricing is flat: Foundation tier at $4,000/month with a one-time $2,500 setup fee, unlimited inbound minutes, monthly tuning included, and 30-day cancellation. No annual contract, no per-call fees. HIPAA: BAA executed with every covered entity. Twilio HIPAA-eligible Voice + Conversations, AWS HIPAA-eligible compute/storage, AES-256 at rest, TLS 1.3 in transit. PHI access logged and audited; no PHI sent to non-BAA subprocessors. Patient AI-handling disclosure in greeting per ONC guidance. No clinical advice given; clinical urgency escalates immediately to licensed staff or 911. If you are a member of the local chamber (www.walthamchamber.com), ask about the chamber-member referral discount.
frequently asked — medical practices in Waltham
Yes. Ascero AI signs a BAA with every covered entity. Voice runs on Twilio HIPAA-eligible products; storage and compute on AWS HIPAA-eligible services. PHI is encrypted at rest and in transit, access is logged and audited, and no PHI flows to non-BAA subprocessors. Patients are informed the call is AI-handled.
Epic (via FHIR R4 + USCDI), Cerner / Oracle Health, athenahealth, eClinicalWorks, NextGen, DrChrono, AdvancedMD, Practice Fusion, and Allscripts are native integrations. The agent writes appointments, refill requests, and triage notes directly into the EMR.
Configurable per practice with a clinical-advisory review of triage rules. Default thresholds: chest pain, stroke symptoms (FAST), severe bleeding, suicidal ideation, anaphylaxis = immediate 911 referral or on-call nurse transfer. Everything else routes to next-available appointment or nurse callback. We require a licensed clinical reviewer on the triage rule sign-off.
It captures and validates refill requests — same medication, same dose, refill-eligible flag check, no controlled-substance Tier 2 refills via voice. Validated requests route to the provider's in-basket as queued refill orders. No prescription is ever sent without provider sign-off.
The agent does not read clinical results over the phone. It confirms whether results are available and offers a same-day callback from the nurse line. Results are conveyed only by licensed clinical staff per practice protocol.
