He and 22-year-old Jordan March were hurt in the attack which saw a car repeatedly drive into people in the street outside the Bournemouth arts and entertainment venue in the early hours of Sunday morning.
Posting on Facebook, Louise said “a maniac” had been thrown out of The Winchester on Poole Hill before getting into a car and repeatedly ramming into people.
She added: “Mark was one of the people badly hurt with 30 stitches to his face, internal stitches, a glued chin and fractured wrist to name a few. He is such an amazing guy and has created such an amazing space for us all that it is so very sad and upsetting for this to happen to him and see him left like this because of a lunatic.”
Louise said Mark is taking time off work to recover and that the venue is closed until the weekend.
She urged supporters to donate to a collection she has started for Mark and added: “If anyone would like to give something it would be greatly appreciated to help him and the Winchester through this tough time.”
Mark is a supporter of law and order and recently sponsored a Neighbourhood Watch scheme in the area. He also bought a metal detector in a bid to ensure customers could not smuggle knives into the venue.
Jordan March suffered ligament damage and spent 24 hours in hospital following the incident.
She told the Daily Echo: “It was like something out of a film. I was sat having some food and the next thing some psycho is driving around trying to hurt everyone.”
Witnesses described seeing a grey BMW estate during the incident, which was later found abandoned on the East Overcliff.
The offender is described as white, in his late 20s, about 5ft 6ins tall and of stocky build with short, dark hair and dark clothing.
Anyone with information is asked to call Dorset Police on 101 or the free and anonymous Crimestoppers line on 0800 555 111.
