About Us

Miriam Martinez Callejas

Superintendent Pharmacist & Founder

As a pharmacy student, Miriam learned to admire the independent spirit of pharmacy and to understand the art of formulating. Her first pharmacy job was in a compounding pharmacy and it was there that she developed the passion for helping others using her experience and knowledge of medicines. Roseway Labs allows Miriam to provide the best medications to maintain a patient’s health and wellness. Miriam holds a Master’s Degree in Pharmacy with international experience in bio-pharmacy research, compounding and nutrition.

Elizabeth Philp

Chief Executive Officer & Founder

Having been obsessed with making ‘lotions and potions’ as a child, Elizabeth has come full circle. The journey has been diverse, taking in roles in HR and management consultancy before branching into independent consulting and then leading a small healthcare business. This experience, along with her experience as a mentor for the Prince’s Trust and London Business School, gave Elizabeth the desire to create Roseway Labs. In those moments when she’s not building Roseway Labs into the most exciting pharmacy around, Elizabeth likes to spend time with her young family and at her weekly sewing class. Elizabeth holds a BSc in Chemistry and Mathematics, MSc in Organisational Behaviour and an MBA from London Business School.

Gurdip Rehal

Quality Director & Founder

Gurdip’s appetite for pharmacy was evoked when he was a young boy, working in the local chemist shop after school. From there on, he went on to set up and own his own pharmacy. When the opportunity to really get involved in how medicines are made came up, he grabbed it with both hands, performing the role of Director and Head of Quality at a licensed facility. At Roseway Labs he has found his perfect fit, drawing on his experience as a pharmacist and in quality assurance to ensure patients always receive the highest quality medicinal products, to meet their unique needs. Gurdip holds a Bachelor’s degree in Pharmacy and a post-graduate diploma in industrial pharmaceutical studies.
