Reece Harnell, Dec 2025

"Very talented artist running a very accommodating establishment. Patient and kind and full of good advice regarding tattoo design style and placement. Highly recommend. I have had three from her thus far, all relatively small and simple pieces but still done with care and I've seen first hand the quality of her larger pieces and they're also top notch!"

Jacqui Compton, Dec 2025

"I would like to say a great big thank you to Gen. I had a tattoo done yesterday. Gen was amazing so helpful and put me at ease. Nothing was too much trouble. I am going back to have another tattoo very soon"

Nina Dunlop, Oct 2025

"It's been 25 years since I had my first tattoo, so to say I was a little nervous was to say the least.!!!..
But I shouldn't have worried, Gen was so kind, attentive and reassuring.
I'm an OAP and she didn't make me feel out of place at all.
I'm delighted with my tattoo in memory of my sister I lost recently.
I don't think it will be long Gen before I'm back for another.
Thank you again!"
