The 33 year old is a familiar face following several guest appearances last season.
Having took up the reigns earlier this month she has enjoyed a positive first few weeks in the role since the squad returned for pre season training.
Predominantly a fly half or centre, Tara has an enormous amount of playing experience having represented the Army, Durham County, Reading, Acklam and most recently Sunderland Flames.
She was also one of the first seven Durham County Women's players ever to receive a county honours cap in 2017.
Tara will be assisted by Lee Dodgson, Hartlepool A captain Rory Craig and Director of Rugby Liam Lester.
Lester commented: "First and foremost Tara is an excellent rugby player and we saw evidence of that in her appearances for the club last season. She has vast experience on the field and that can only help the rest of the team in their development. She's a really exciting signing.
"When we set about looking for a new coach we were keen to find someone that was energetic and enthusiastic. Tara has both in abundance as well as the knowledge that she has gained through many years playing the game.
"We are delighted to be able to support her as she takes her first steps into coaching. I have no doubt that she will be a success here and build upon the strong foundations that have been laid over the last year or so.
Breslin added: "I'm really excited by this opportunity and look forward to helping the team develop even further. We've enjoyed a great start to pre season training so far, the atmosphere and effort has been fantastic, and our numbers continue to grow.
"We've got a great group of players that are really committed to wanting to improve and get better. They're a pleasure to coach and I can't wait to see what we can achieve together this season."
After reforming last year there are exciting times ahead for Hartlepool Ladies as they get set to embark on their first league campaign in nearly fifteen years this season.
