From Missed Calls to Measurable Growth: A Lesson from ADSO

One theme ran through this year's ADSO meeting: how to stimulate organic growth. There are always multiple levers, but one of the fastest is operational rather than promotional, and it's hiding in a number most groups never see. The patients who called, hit voicemail, and quietly booked elsewhere. In her session "From Missed Calls to Measurable Growth," Sadiye Akturk of Straumann Group Enterprise Solutions built the case that your schedule shows who arrived but says nothing about who gave up. To size that gap for multi-location groups and DSOs, we looked at the call data.

The Hidden Problem in Every Group

At a single location, a manager can sometimes feel when calls are slipping. Across a group, that signal disappears into the average, taking four quiet costs with it: missed calls become missed revenue; leaders lose visibility into how each location's phones perform; the patient experience varies by which office answered; and a front desk you can't observe is one you can't coach, harder still across dozens of them. None of it shows up cleanly on a P&L.

You Can't Improve What You Can't Hear

Sadiye Akturk put it in one line: “You cannot improve what you cannot hear”. In a multi-location group, hearing is the hard part. A single office can field thousands of calls a month, so reviewing them by hand is impossible; performance swings between sites and shifts, so the average hides as much as it shows; and with calls rarely captured, most phone decisions get made on instinct. The intent is good. The information hasn't been there.

What 540,133 Calls Revealed

We analyzed 540,133 inbound calls across single-location offices, multi-location groups, and DSOs. We expected results to track with size or market. They didn't. Inside every segment, the spread between strongest and weakest was striking: multi-location groups ran 47.3% to 69.4%, the widest gap we measured; DSOs, 54.8% to 70.0%; single-location practices, 53.7% to 71.4%. Top performers everywhere cleared 69%; the bottom fell below 55%. What separated them wasn't practice type. It was what they did operationally. For a group, the variation between locations is operational, not structural, and it's already in the call data.

The Math Is Worse Than It Looks

Drawing on data from more than 12,500 practices, DentistryIQ puts the production from one new patient well into the thousands, counting treatment and years of recare. Across a group, twenty points of conversion on the same calls is the difference between two growth curves. Much of the loss happens early: Dental Economics reports that a third of marketing-driven calls never reach a person, and 87% of patients who hit voicemail never leave one. They call the next practice instead.

It Is Rarely a Marketing Problem

When new-patient counts slip, the marketing budget is the first suspect. Usually it's doing its job. The patient already saw the ad and chose to call. The gap opened after the call connected, or because it never did. A quieter problem, and a more solvable one.

What Most Groups Try First

Most groups reach for the tools they have. The most common is hiring more front-desk staff, which helps capacity, but the phone surges Monday mornings and after hours when no one's there, and hiring is harder than it once was (staffing tied for the top concern dental leaders named heading into 2026, per the ADA Health Policy Institute). Next come manual call audits, useful but impossible to scale, and basic call tracking, which counts calls but not why they were lost. Each eases one of the four problems and leaves the rest open.

What the Top Performers Actually Do

The high converters (booking 65% or more in every segment) shared four habits, none about bigger teams or budgets.

• They respond faster (a missed call returned in under 2.5 hours, versus about five).
• They book faster (first call to appointment in 15 days, versus 22).
• They fix the call flow (roughly 12 points fewer calls lost before pickup).
• And they staff for demand (about one in 25 calls met no one, versus one in 13 at the bottom).

Where to begin depends on the group: scheduling speed for multi-location groups (booking within 20 days converted at 60.5%, beyond 20 at 54.1%); capacity for DSOs (worth about eight points); response time for single-location offices. Northwest Dental Group lifted its answer rate from 70% to 90%, its missed-call return rate from 50% to 100%, and its inquiry-to-booking rate from 62% to 82%, the same patients calling, more of them booked.

How VoiceStack Recovers Missed Production

Every signal separating a 47% converter from a 71% one is already measurable. VoiceStack is a phone system built for dental groups that treats the phone as part of production, not a utility that happens to ring. The top performers' four habits aren't personality traits. They're dashboards and settings:

• Visibility into answer rate and response time by site, with each lost call flagged before or after pickup
• Missed-call response and tracking that turns every unanswered call into an immediate text and a tracked callback
• An AI Receptionist that answers and books after-hours and midday-rush calls instead of sending them to voicemail
• And recordings and summaries to coach conversion on evidence

Groups act on this quickly. Active Dental reached a 93.4% answer rate; Enamel Dentistry found 15% of calls dropping in the phone tree, fixed the routing, and gained almost twelve points.

Dental Depot, with 30-plus locations, recovered 41% of previously missed opportunities and tied roughly $105,000 in new production to a single 90-day window, with no increase in marketing spend.

The Production Is Already in the Call Log

None of this means working the front desk harder. The demand is already there; the patients are already calling. The production sits in the call log, waiting on whether the group can hear it and act. Half a million calls pointed to one conclusion: the constraint isn't demand and isn't size. It's visibility. Learning to hear the phone is a smaller change than it sounds, and it's one of the fastest organic growth levers a group can pull.
