Pros
- Board-certified obesity medicine physicians provide a level of clinical specialization not available on most telehealth platforms
- Hybrid model allows in-person examination for complex cases, medication intolerance evaluation, and physical assessment
- Insurance-accepted model reduces out-of-pocket costs compared to cash-pay competitors
- Full GLP-1 formulary including brand-name Wegovy and Zepbound, insulating patients from compounding supply disruptions
- Prior authorization support included
- Appropriate for patients with significant comorbidities (T2D, hypertension, sleep apnea) who need specialist-level management
Cons
- Geographic availability is limited to select Northeast markets; not a national platform as of March 2026
- Insurance-based model means access depends on plan participation and prior authorization approval
- Not the fastest or cheapest path to a GLP-1 prescription for patients who simply want access and have no comorbidities
- In-person visit requirement (when clinically appropriate) is a barrier for patients who cannot travel to a clinic
- Limited public information on cash-pay pricing for patients without covered insurance
