Stuart Cassidy
Stuart entered the property scene in 2001, joining one of the UK’s largest estate agencies. After nearly a decade of hard work and rising to Partner level, Stuart realised it was time to take his career to the next level. In 2011, he co-founded Cassidy & Tate with his business partner, David Tate, marking the beginning of a new chapter in his career.
After almost 19 years of experience in Marshalswick, selling local homes and building strong relationships with clients, Stuart shifted his focus in 2020 to launch the Land Department within Cassidy & Tate. This is where Stuart truly came into his own, quickly becoming one of the leading Land Directors in the area. He now deals with a range of new homes sites and off-market land sales, helping both buyers and developers navigate the complexities of land transactions.
Stuart is known for his deep expertise, his exceptional client service, and his ability to make deals happen. Whether it’s land or property, his dedication to delivering results sets him apart in the local market.
Outside of work, Stuart enjoys life to the fullest with his wife Frances and their two young children (aged 3 and 4). When he has some free time, you’ll likely find him on the golf course, perfecting his swing.

Duncan Cohen
I’ve been with Cassidy & Tate for over a decade, starting as a junior negotiator and progressing to my current role as Associate Director of Sales. During that time, I’ve worked across a wide range of property types and market conditions, always with the same goal: to deliver a tailored, hands-on service that puts the client first.
What sets my approach apart is the level of personal involvement I maintain throughout every stage of the sales process. I provide honest and informed advice, and stay closely involved right through to completion. For me, offering a bespoke service means being available, responsive, and adapting to the specific needs of each client — whether they’re selling a first home or a long-held family property.
I grew up in Harpenden and now live in St Albans, so I bring a genuine understanding of the local area and its communities. I’m proud to have built long-standing relationships with clients, many of whom return or refer others based on their experience working with me.
My commitment to service has been recognised through consistently positive feedback and a nomination for an ESTAS Customer Service Award — something I value as it reflects the trust and satisfaction of the people I work with.
Outside of work, I enjoy travelling, staying active, and making the most of the outdoors — especially walking my miniature dachshund, Slinky, around Heartwood Forest or Verulamium Park.
