Clarify Medical is now Zerigo Health.

Designed by patients
for patients

Zerigo Health was founded by a psoriasis patient, Martyn Gross, who had excellent results with UVB therapy but found it very difficult to receive in-office treatment three times a week. His concept of a mobile, easy-to-use home UVB system, linked with the patient's physician, inspired years of research and development with hundreds of psoriasis and vitiligo patients and their physicians. Patients designed the integrated technology and service solution we offer today.
