Our Team


I am Shannon O’Leary, founder of HearInAfrica, audiologist and owner of HearInAfrica. I was born and bred in the Southern Suburbs of Cape Town and am a graduate of the University of Cape Town, with a BSc in Logopaedics (1999) and a MSc in Speech & Language Pathology (2002). I am proudly South African and love being an audiologist! I have a special interest in community-based audiology and have worked in a variety of private and public clinical settings, ranging from urban and rural clinics in South Africa, Lesotho, Zambia and Malawi to NHS Cambridge University Hospitals in the United Kingdom.

I serve on the Best Practices Committee of the Coalition for Global Hearing Health and have dedicated my career to having the maximum impact I can for people living with hearing loss in Africa. I firmly believe that all patients deserve the same standards of care and am continuously working on developing new and creative service delivery models to improve access and affordability of hearing healthcare services and hearing aids in Africa.  I am incredibly proud of my team and am focused on creating more exciting positions for audiologists who wish to work in a combination of private and public settings.

I am a mom of two munchkins, 2 dogs and 2 cats. In my spare time my favourite things to do include chilling out with family and friends in front of a roaring fire, exploring new places, wine tasting, antique hunting, renovating and redecorating.


Hi! My name is Tersia Davids, an audiologist at HearInAfrica with a passion for improving access to audiological care. Whilst completing my master’s degree at the University of Cape Town, I had the opportunity to work with audiology students in their clinical and theoretical training before moving into private practice. Outside of audiology, I am a trained organist and have been playing for the past 10 years.


Hello! My name is Emma Siegfried and I am an audiologist with a passion for paediatric audiology! I graduated from the University of Cape Town in 2005 and did my community service at Edendale Hospital in Pietermaritzburg. I subsequently spent eight years in the United Kingdom, based predominantly in London at Hackney Ark Children’s Development Centre. While there I provided, as part of a multidisciplinary team, specialised audiological services to a diverse population of children and was able to further develop my skills in paediatric electrophysiological and behavioural assessments, hearing aid fittings and counselling families of children with hearing loss. Upon returning to South Africa, I ran a specialist audiology service for a private practice in Cape Town, which involved performing Auditory Brainstem Response (ABR) testing on babies and adults. During the same period, I conducted newborn hearing screenings at various hospitals around Cape Town. In 2017 I took on a role as a Clinical Educator, guiding final year Audiology students in the diagnosis and management of babies with hearing loss at Red Cross Children’s Memorial Hospital. I relish the role of being a full-time mom to my two rambunctious little boys – an experience which I feel has provided me with invaluable insight into the families’ perspective when receiving care. I was delighted to join the HearInAfrica team in 2021 and am currently part of the diagnostic paediatric team and school screening programs.


Hi! My name is Safoora Mustapha and I am an audiologist at HearInAfrica. A passion to serve and uplift communities has paved the way to choosing my career as a speech-language pathologist and audiologist. After graduating in 2012 from the University of Witwatersrand, I worked closely with an NGO in my hometown of Gaborone, Botswana. I have completed my Masters in Audiology. My favourite pastime is creating art and spending time in nature.


Hi! My name is Simone Delo and I am an audiologist. Born and bred in Cape Town. I graduated from the University of Cape Town with a BSc (Hons) in Audiology and completed my community service at Kimberly Hospital in 2018. I subsequently entered private practice where I focused on refining my skills in adult diagnostic hearing assessments, hearing aid fittings/repairs/troubleshooting as well as counselling individuals and their families about how to adapt to life with hearing loss. I have a special interest in the assessment and rehabilitation of balance and vestibular disorders and have completed multiple short courses, practical workshops and international masterclasses relating to balance and vestibular pathologies. I am also a clinical educator at UCT’s Faculty of Health Science (with a focus on hearing aid fittings and vestibular rehabilitation therapy), as well as a clinical supervisor and volunteer for UCT SHAWCO – the largest student-led NPO in Africa.

I am a mom of 3 dogs and 1 cat. In my spare time I love long walks on the beach, ‘catching’ sunsets, restaurant hopping and spending quality time with family and friends.


Hello! I am Sharon Magnuson and am a receptionist and audiology assistant at HearInAfrica. I grew up in Zimbabwe and moved to the Cape in the late seventies. I worked for CDM in Namibia and moved back to the Cape in 1986. I joined the HearInAfrica team in 2020, having worked as a personal assistant to dermatologists and gynaecologists for over 20 years before that. I am a mother of two and Gran to five amazing grandchildren. I love a good book, long walks on the beach and the garden is my happy place.


Hi! My name is Wendy Fisher and I am a born and bred Capetonian with one beautiful daughter. Before joining HearInAfrica in 2012, I worked as a personal assistant for a physiotherapist and sports tour coordinator. I love spending my free time on charity work, playing tennis and gardening.


Hello! My name is Colleen Curtis and I am happy to introduce myself as a receptionist and virtual assistant at HearInAfrica. I am a born and bred Capetonian whose joy and sense of fulfilment stem from my family, close friends and pets, who share my life in this undeniably beautiful part of the world. It is here, in this diverse environment, that I enjoy walking my dogs on the beach or the greenbelt, relaxing around the pool, reading books and enjoying nature.

I have always loved being actively involved in the welfare of both people and animals. My work experience spans both these spheres of life, with management positions in a property sales environment and an animal welfare organization. Having invested so many years in service industries, I am excited to find that the foundation I have built stands me in good stead to support HearInAfrica’s team of dedicated audiologists and to bring you, our clients, the quality of service you deserve.
