Our Business Development Consultants

Alan Tumilson
Business Development Manager
Managing your region and team of expert consultants
"I’m proud to work with a team of dedicated and highly experienced Business Development Consultants who are passionate about helping dental practices achieve their goals and realise their full potential. Together, we work closely with our clients to provide tailored support, guidance, and solutions that drive long-term success.
I joined Denplan in 2014, initially supporting practices across Scotland and Northern Ireland. Prior to this, I built my career in the advertising and marketing industry, working as a Sales Consultant with some of the UK's leading media organisations. These experiences have given me a strong understanding of relationship management, business growth, and delivering value to clients.
Outside of work, I enjoy spending quality time with family and friends. On most Saturdays, you'll find me supporting my local football team and enjoying the camaraderie that comes with it."

"I joined Denplan in May 2020, having spent over 30 years in the dental industry. I was a dental nurse in a practice for many years in a Denplan member practice, so I have first-hand experience of the benefits to patient and practice alike. I’m really excited to be able to work closely with practices to help them not only achieve their business goals but also provide the quality dentistry their patients deserve.
Outside of work, I enjoy swimming, spinning & travelling."

“After a career in dental practice, I moved on to be a Key Accounts Manager at a global dental consumables business supporting practices in Scotland and Northern Ireland. Since then, I’ve had roles with various leading dental manufacturers and retailers, and before joining Denplan in 2022. With my experience in dentistry, I have a strong understanding of customers’ needs and requirements. I’m adaptable to various dental environments and have extensive knowledge of all things dental.
Outside of work, I enjoy travel, my favourite destination is Sri Lanka, and I enjoy attending sporting events such as Wimbledon & The Ryder Cup.”
