Undertook further postgraduate study for a Masters of Clinical Pharmacy(Merit) in 2014 and qualified as a Pharmacist Independent Prescriber (PgCert) 2016.  I became an LDN Specialist in 2021, and I am midway through a Postgraduate qualification in Health Leadership and Management.

Continual education is essential for me to understand the complex medical issues of my patients and my personal growth. During my career, I have worked in each of the key sectors of pharmacy, namely: community, hospital, industry, and private practice.

Since 2018, I have worked in a number of private sector consultancy roles.

My particular areas of interest are the clinical use of antithrombotics and immunosuppression in solid organ transplants.   Working directly with patients has allowed me to develop a professional, empathetic, non-judgemental, caring manner, with excellent communication skills used to effectively counsel patients in a clear and supportive way.  

Core to my practice and beliefs is adopting a holistic patient-centered approach to ensure each person receives the best and most appropriate care for their individual needs. 

In my spare time, I enjoy singing, cinema, travelling etc.
