“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.”

Sian and Mark were responsive, professional and kept me informed throughout the process. They handled the negotiations efficiently and helped move the purchase along smoothly. I would happily recommend them to anyone buying a property.

Julie, DaventryMay 2026

From start to finish, Mark was incredibly communicative, always keeping us informed and making sure we understood every step of the process. He took the time to explain everything clearly, which really helped take the stress out of selling our home.

Timea, DaventryMay 2026

Sian, you and Mark have both been great at keeping in contact plus friendly and helpful in every way. Mark's valuation of Scott Close was pretty much 'bang on' and the fact he got us to our asking price within a very short time of it being marketed was truly impressive!

Martin and Sue, DaventryMarch 2026

Got the valuation done, got it on the market and got it sold in rather a short period of time with no messing about. That's all you want at the end of the day. Thanks very much Mark. Top man.

Mark service in the British Army for 27 years!

Working the first few years in a rising market then throughout a tough recession, he very quickly gained a wealth of experience in the property business. Mark served with the British Army for 27 years in a front-line infantry regiment. He travelled the world and spent many years in various trouble spots. He enjoyed it, but knew that as he got older, he would need to find something else to do as a career.

Mark’s approach to every transaction is both personal and professional, as Victoria from Daventry noted: “Mark showed us our home multiple times and was always contactable regarding questions and queries.

His knowledge of Daventry, our neighbours and location was invaluable to us to making our decision.” His deep knowledge of the area and dedication to understanding clients’ needs help ensure that every client feels fully supported throughout the process.

When faced with challenges, Mark’s calm and patient approach ensures a positive outcome. Deborah from Daventry shared, “Mark took time to explain everything. Was at the end of the phone when required… he made it easier.” His ability to guide clients through stressful situations and ensure they feel informed and confident in their decisions is highly valued.

Mark’s clients appreciate his unwavering support, even after the sale is completed. Robert from Daventry noted, “Mark went above and beyond to make the entire process smooth and stress-free. He even gave me his mobile number to contact him while he was away on holiday!” This dedication to staying available and ensuring clients are fully supported, even beyond working hours, is a rare quality that sets Mark apart.

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. We have moved many times and used lots of different agents, but Mark was the easiest to work with.” Mark’s ability to maintain excellent communication and provide a stress-free experience for his clients is key to his success.

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.

With his professionalism, dedication, and ability to deliver exceptional results, Mark is the agent you can rely on for a seamless property experience.

We have always had great service from Mark at Campbells when we’ve bought and sold properties, we wouldn’t go anywhere else. Great communication, Mark always kept us up to date on what was happening with our sale.

Clare, BraunstonFebruary 2026

Mark was a friendly guy on first meeting at the first viewing I was so grateful for his help along the process with trying his absolute best to battle with the solicitors. It was a lengthy process but could not of asked for me from Mark. And also massive thanks for the help in getting the sofa in.

Jamie, DaventryFebruary 2026

I got in touch with Mark at Campbells when I wanted to sell my property for a move to Cornwall. I knew Mark from selling my mothers house so didn’t hesitate to to get back in touch with him. He is very knowledgeable and listened to what I wanted and made suggestions to help me with the sale of my property Very efficient and friendly service, wouldn’t hesitate to recommend him. And needless to say I got a sale within three weeks.

Maureen, DaventryFebruary 2026

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.
