”“After serving 27 years in the British Army with a front-line infantry regiment, being bounced around the world at short notice was interesting, exciting and very often an exhilarating way to spend the younger years of my life. At the peak of my Army career I had reached the rank of Warrant Officer Class 1 and had spent many years in various trouble spots worldwide. I decided at the age of 43 it was time grow up and start working towards a new career.”

In addition to his professionalism and expertise, clients also highlight Mark’s friendly and approachable nature.

As Melvyn from Daventry put it, “Simply the best, and always easy to talk to, always there when needed.

Mark’s reputation for going the extra mile is widely recognised, and Gaynor from Long Buckby summed it up perfectly: “Mark was absolutely fantastic and took so much of the stress and strain from us during the sale and purchase of our properties… He was more like a supportive friend than our agent.” This genuine care and support for clients during difficult times highlight Mark’s unique approach to estate agency.

“Excellent service. Mark and everyone at Campbells were super helpful in assisting us towards purchasing our first property. He swiftly answered all the questions we needed and made buying our first home a lot easier than we thought it would be. There were some frustrating delays on our own end, but he was always there to help and advise. Further to this, it didn't feel like we were on our own in the process, which was reassuring as first time buyers.”
