Cubex Staff Adam Shulberg
Mr Adam Shulberg – Senior Audiologist and Managing Director

Qualifications – FSHAA RHAD

He studied at the Royal National Throat Nose and Ear Hospital, Gray’s Inn Road and in 1980, qualified as the youngest audiologist in the UK.

By 1984 he was actively involved in the running of an Audiology clinic in Madrid with ‘satellites’ in Northern and Southern Spain, whilst also establishing himself in the UK practice. Adam became Managing Director of Cubex in 1995 when the London based operation moved to 25 New Cavendish Street.

He works closely with The IDA Institute to help with the process of generating and providing innovative, practical and actionable knowledge on the human dynamics associated with hearing loss. This knowledge is filtered through to the rest of the team at Cubex. He is a great facilitator and his passion and many years of experience in the field makes him a perfect mentor.

Cubex Staff David Engelman
Dr David Engelman – Senior Clinical Audiologist & Complex Audiological Needs Specialist

Qualifications – Doctor of Audiology (Au.D.)


David was born and raised in New York City, where he received a BSc in psychology, and had initially considered pursuing a career in mental health. He was drawn to the field of audiology after his grandmother began seeing an audiologist for the care of her hearing loss. Through this journey with a loved one, he was able to witness firsthand the benefits of improving hearing and communication and undergoing audiological treatment.

David was struck by the strong correlation between the fields of psychology and audiology, particularly with audiology’s focus on cognitive well-being. He decided to pursue a career as an audiologist and was awarded the Doctor of Audiology (Au.D.) degree in 2014 by the City University of New York.

David began his career working for a private practice in the Finger Lakes region of rural Upstate New York. He has since relocated “across the pond” to the UK, where he has worked as an audiologist for the NHS in Essex. David is excited to work once again in private practice by joining the team at Cubex. He very much values the holistic approach that Cubex takes to hearing healthcare, and enjoys partnering with patients and their families to achieve the best possible outcomes in their treatment.

Outside of work, David loves to travel and explore the world, whether it’s backpacking to a remote corner of the globe or merely taking a walk through the English countryside. He has so far been to 29 countries and looks forward to adding many more to his list.

Dr Saima Rajasingam – Clinical Audiologist

Qualifications – PhD, Audiology


With a mother who is a doctor and a father who is an electronic engineer, Saima was drawn to a career that was an elegant synthesis of both professions. She undertook her BSc (Hons.) in Audiology at the UCL Ear Institute, where she was awarded student prizes for both academic and clinical excellence. Through working with patients, she grew to better understand the real-life, everyday implications of hearing loss.

Prior to joining Cubex, Saima worked in the NHS and taught students of Clinical Audiology. She began her PhD in Auditory Perception at Aston University (Birmingham) in 2012 and achieved her doctorate in 2016. Her research explores some of the ways in which the brain makes sense of the complex mass of sounds arriving at our ears. Saima has continued to remain involved in research and teaching as an Honorary Lecturer at the UCL Ear Institute, incorporating evidence-based practice into the clinical care we offer at Cubex.

“What drew me to Cubex was the commitment to high quality, individually-tailored care coupled with innovative, scientifically-driven treatments. What resonated most with me was the sincere commitment to helping people engage effortlessly with those they love and the world around them. I aim to view each and every person who steps through the door with fresh eyes, as unique individuals, deserving of the best possible care.”

Saima has maintained commitments within the voluntary sector for over a decade now. Specifically, within Audiology, she assisted with developing services in the Northern Province, Sri Lanka (2011 and 2013) providing basic training to staff and students at Jaffna Teaching Hospital. More generally, she has been involved in the Ending Loneliness Project, a voluntary movement addressing the increasing impact of loneliness on young and older adults in the UK, alongside her interests in global healthcare.

Nadia Williams – Cubex Host


Nadia grew up in West London Paddington and studied at Newham University completing a BA Hons Counselling Studies. She holds a qualification in intermediate and advanced Health and Social Care.

Nadia has a strong passion for counselling that has allowed her to help other people through difficulties in their lives with care and empathy. As a humanistic counsellor, Nadia believes in the worth and value of a human being. Not so much focusing on their experiences but on their own ability to understand and develop a positive image of self-worth. Humanistic counselling focuses on the individual’s strengths and offers a safe non-judgmental environment for a person to explore and healing to begin. This is her calling.

Why Cubex?

I chose to work with Cubex as it offers a very therapeutic service for all their patients. Cubex takes the time and effort to make their patients feel comfortable, relaxed while in their establishment. To know and understand their patient’s needs. This is very similar to the counselling world.

The beautiful aroma which travels through the building and the friendly staff willing to go the extra for their patients makes the whole experience of Cubex one to remember.

What do you get up to outside of Cubex?

When not working for Cubex I love to swim, my mother calls me her little Mermaid. I won numerous awards in school for swimming I find this to be my outlet of peace. Reflection is another therapeutic method I have learnt on my counselling journey which benefits me in all areas of my life.

Cubex Staff Dana Mathewson
Dana Mathewson – Audiology Trainee


Dana’s desire to work in Audiology began while studying at the University of Arizona, obtaining her bachelor’s degree in speech and hearing sciences. To her, audiology works like a large puzzle, with integral pieces that we must assess before moving onto another. This aspect of problem-solving makes Audiology a new and exciting profession that keeps evolving and piquing her interest. Dana is also interested in helping people with disabilities since she acquired a physical disability at the age of 10 and felt she can empathise with patients from all walks of life.

Dana recently moved to London from San Diego, California to obtain her MSc in Audiological Science with Clinical Practice, and will be completing her clinical practicum at Cubex this year. She was attracted to the high quality of London’s Universities and wanted the challenge of immersing herself in a different culture.

Dana is drawn to Cubex for their commitment to person-centred care, commitment to excellence, and innovative approaches to treatment. She knows she has a lot to learn regarding patient care and feels that Cubex is the best place to acquire the necessary professional skills.

Outside of Audiology, Dana is a professional athlete and Paralympic tennis player who represented the USA at the 2016 Paralympics in Rio and hopes to do so again in 2020 at the Games in Tokyo.
