Specialist Healthcare Accountants Team
Meet Our Director

USMAN SIAL – BSC (HONS), FCCA
founder & Director
Growing up, I was surrounded by hard-working family members. While my dad was a lawyer, my grandfather and uncles had entrepreneurial spirits. In our South Asian family, many loved medicines, including my parents. They hoped I’d become a doctor like my brother. However, my passion was for numbers, so I chose accounting. Despite initial doubts, my family came to respect and be proud of my decision.
During my early years in accounting, I trained and qualified with medical and healthcare specialist accountancy firms. This invaluable experience, combined with my family’s healthcare background and my passion for numbers, made something clear: many healthcare professionals desperately needed specialised financial guidance. Recognising this unique intersection of my interests and the market’s needs, I decided to establish my own firm, focusing primarily on the healthcare sector.
In a delightful twist of fate, I also married a dentist, further intertwining my personal life with the world of healthcare. Read More
