About Sleepspan
Sleep medicine physician review for lifestyle, preventive and whole-person clinics.
“Sleep labs and specialty referrals are essential when indicated, but they are only one part of sleep care. Lifestyle and preventive clinics have an extraordinary opportunity to improve the everyday patterns that shape sleep. I built Sleepspan to make that practical.”
