Martin Overington
Managing Director

A highly experienced quantity surveyor and with a background in prestige commercial and residential construction, Martin set up Stenball 15 years ago.

He is passionate about consistently delivering exceptional quality projects for Stenball’s clients, no matter what challenges may arise (including the removal of a series of high security safes from a partly demolished bank, under police armed guard, in the midst of the Croydon riots).  He has cultivated a long-serving, close knit team who understand and support his vision.

In his [limited] downtime, Martin is a keen classic car enthusiast, competing in the famous Le Mans Classic race a total of SIX times – and has conducted his own personal refurbishment project – on a heritage hotel in France. Martin lives in Surrey and is married to Felicity, a GP.  They have two grown up children.

Steve Kitney
Financial Controller

Steve, from Alton, Hampshire, is registered with The Institute of Chartered Accountants in England and Wales (ICAEW).  He has been with Stenball for over 10 years and oversees financial strategy and management for all Stenball group companies.  Based with the head office team in East Horsley, Surrey, he says the favourite part of his role is helping others to help the company run seamlessly.

Family man Steve is married and has two teenage children, Alex and Mary.  He’s an endurance sports nut (which “helps him keep going at Stenball!”), with running, cycling and squash on the fitness agenda, but also enjoys nothing better than losing himself in a good book.

Martin Brown
Director, Major Projects


David Drummond

Farnham based David has been with Stenball for over 10 years.  With a typical day spent pricing, organising and visiting sites across the south of England, he is a busy man.  He’s committed to delivering high quality projects against tight deadlines and often with considerable logistical challenges.

David, who was a City bond broker in the Japanese market prior to moving over to the construction industry, is married with three grown up children.  Their careers span banking and the ski and TV/film industries.  A talented family!

Trevor Craggs, GradIOSH
Director, H&S Consultant / Trainer

Formerly with the military (he served for 24 years, first in the Royal Electrical and Mechanical Engineers, and then the Light Dragoons as a tank commander and weapons instructor), Trevor was always the perfect candidate for intelligently, efficiently and effectively communicating the importance of health and safety to a wide audience.  Training originally as a GradIOSH with the Institution of Occupational Safety & Health, he’s currently working towards chartered status, the very highest level within the profession.  He both advises clients on H&S and trains Stenball teams on best practice and the latest developments.

Despite hailing from Sunderland, he’s an avid supporter of its fierce club rival Newcastle United, so health & safety training is no doubt a bonus at matches!  Trevor is married with three children, the youngest of whom has just joined the RAF.
