How a National Anesthesiology MSO Enrolled 21% of Eligible Clinicians in Disability Coverage -- Against a 4% Industry Baseline
A fast-growing MSO with 600 eligible 1099 clinicians spread across the country had no disability coverage and no benefits infrastructure. Hollowtree ran a full enrollment campaign -- communication, education, and payment -- without requiring HR to manage the process. Participation reached 5x the industry average in under four weeks.
The Client
A national anesthesiology MSO formed through the merger of two practice groups, with clinicians spread across the US. The workforce had previously been W-2 but converted to 1099 as part of the acquisitions, losing access to employer-sponsored benefits in the process. With ambitious growth goals and a tight hiring market, the organization needed to differentiate its offer to clinicians -- but had no benefits infrastructure and no payroll system to support coverage.
Why the Usual Approach Wasn't Working
The MSO faced a compounding set of problems that made a traditional enrollment approach impossible. Geographic spread: 600 eligible clinicians worked across practices nationwide. There was no single site to visit, no all-hands meeting to present at. Clinicians worked unpredictable hours and were not desk workers -- they did not reliably open or respond to email. Structural exclusion: As 1099 contractors, these clinicians were locked out of group coverage entirely. Their only option had been individual policies -- expensive, slow (3+ months of medical underwriting), and unfamiliar to most. Many carried residual coverage from residency that no longer matched their income. All were materially underinsured. No infrastructure: With no payroll system, there was no mechanism for premium deduction. The MSO had no benefits team, no enrollment platform, and no vendor relationships focused on individual coverage for contractors. Credibility gap: When presented with guaranteed-issue, own-occupation coverage at group economics, clinicians were skeptical. The most common reaction was "this seems too good to be true -- what's the catch?" The broker who introduced Hollowtree had been selling financial planning products to individual clinicians and saw an opportunity to help the organization itself. But neither the broker nor the MSO understood the operational complexity of running a successful enrollment campaign across a distributed 1099 workforce.

How Hollowtree Structured the Rollout
Coverage That Matches the Risk
Hollowtree partnered with Sun Life, which offers a physician-specific group disability product. The core of the coverage is a true own-occupation definition of disability -- if a clinician cannot perform the specific procedures they are trained in, the benefit pays. This coverage extends to age 67 and beyond, unlike most group LTD plans that revert to an any-occupation definition after two years. To solve the payment infrastructure problem, Hollowtree's proprietary enrollment platform incorporated ACH, Apple Pay, and credit card options -- making monthly premium payment seamless without any payroll system.
Reaching Clinicians Who Don't Sit at a Desk
Hollowtree deployed an omnichannel campaign designed for a workforce that does not sit at a desk: personalized email sequences, SMS outreach, direct mail, voicemail drops, and an on-demand call center for inbound questions. Where possible, Hollowtree engaged clinical directors and recruiters who had personal relationships with the clinicians, briefing them on the plan details so they could speak to it credibly. This peer-layer communication proved critical for a population skeptical of unsolicited outreach. One early challenge: email deliverability suffered due to inconsistent contact data provided by the MSO. Hollowtree now invests in cleaning and validating data before launching any enrollment campaign -- a process improvement born directly from this engagement.
15 Minutes to a Decision
One-on-one consultations took no more than 15 minutes and converted at a near-100% rate. Webinars were lightly attended but led to high conversion among those who joined. The enrollment microsite -- Hollowtree's proprietary platform, mobile-optimized -- allowed clinicians to review plan details and complete enrollment in under 5 minutes, including payment setup. Several clinicians who fell slightly under the eligible hour threshold indicated a willingness to add shifts in order to qualify -- a signal of how strongly they valued the coverage once they understood it.
What Changed
In under four weeks, Hollowtree achieved a 21% participation rate among eligible clinicians -- more than 5x the typical 3-4% voluntary enrollment rate for individual DI in a 1099 population. The MSO invested zero internal HR hours in the enrollment process beyond a single introductory email.
What made the difference: clinicians were not resistant to disability coverage -- they were resistant to a process that felt unfamiliar and an offer that seemed unlikely. Once Hollowtree established credibility through peer-layer communication, plain-language education, and a frictionless enrollment path, participation reached 5x the industry norm. The MSO now leads with disability coverage as a recruitment benefit in conversations with candidates.
