Meet the team.

Lisa Medhurst, Office Manager

I have been the office manager at Triangle for 14 years, I manage the office and make sure all supplies are fully stocked.

I answer incoming calls, assist the Directors, answer emails and deal with PPE, Ordering and CSCS Tests and certification plus many other day to day duties.

I enjoy spending time in our garden at weekends and love eating out, we also love spending time with our family and adore our 6 Grandchildren and two Saluki x Greyhounds.
