Hashir International Institute

What Hashir International Institute does

Hashir International Institute is a UK-based private specialist clinic and independent research institute founded in 2013, focused on the assessment and rehabilitation of misophonia, tinnitus, and hyperacusis in children and adults. Its core clinical product is a 14-session, video-delivered premier therapy package that combines cognitive behavioural therapy (CBT) with multidisciplinary consultations from audiologists, clinical psychologists, health psychologists, occupational therapists, and neuroscientists. The institute has developed proprietary psychometric instruments, including the 4C questionnaire and the Misophonia Impact Questionnaire (MIQ), and codifies a decade of research into its treatment protocol. Operations run from clinics in Guildford (54 Quarry Street) and London (167-169 Great Portland Street), with additional paediatric occupational therapy delivered via a partnership with High Five OT in the Guildford area, and globally via video consultations.

The business model is a multi-stream private-pay services platform. Patient revenue comes from the premier therapy package, an internet-based CBT (iCBT) guided self-help programme, specialist paediatric OT, and clinical assessment services. Professional and research revenue comes from the CBT-Hear training programme (CPD-certified), international conferences (ICHM, World Tinnitus Congress), sponsored research, and university collaborations (Cambridge, Surrey, Sussex, King's College London, Oxford, Iowa, Illinois, Duke, La Trobe, Durham, Groningen, and others), supplemented by retail book sales. Go-to-market is sales-led through direct clinic appointments, self-referral, GP referrals, and professional training channels; marketing relies on the institute's YouTube channel, Patient Education Programme webinars, blog content, and the public-involvement Sound Off art competition. The institute employs 17 staff, including senior clinical psychologists earning £53,755–£60,504 and occupational therapy assistants earning £24,071–£25,674, and is founder-led by Dr. Hashir Aazh, a pioneer of audiologist-delivered CBT for tinnitus and hyperacusis.
