Meet the Team

Brian Costello

Job Title: Managing Director

Brian has been working in mental health for over 20 years and has a special knack for helping young people change their mental health.  He founded HeadStrong in 2007.  Brian’s got a special talent for filling a diary so full he occasionally forgets where he is even when he’s there.

Julie Bell

Job Title: Head of Schools

JB is a teaching legend. An ex Primary Head Teacher, Julie left teaching to come to HeadStrong and brought with her years of experience, creativity and knowledge. When she’s not watching a show somewhere we occasionally get her into work to be awesome.


Cheryl Milligan

Job Title: Accredited Coach

Cheryl worked in Paisley Grammar for many years before her love for mental wellbeing steered her towards her career with HeadStrong.  Unless you’ve got all afternoon don’t ask her what crystal would be best to balance your heart chakra!


You’re not alone, you’re not the first to go through it, you’re not going to be the last to go through it.

Dwayne Johnson

Mark Long

Job Title: Accredited Coach

Mark’s background includes a variety of teaching roles mostly in the drama, singing and acting sphere where his last job before joining us was running his own school. He once played Kenickie in Grease at the Kings but tbh he’s probably already told you that.

Liz Sally

Job Title: Practice Manager

As Liz will tell you she keeps everyone else organised. As Practice Manager Liz is the super organised one amongst us and although you might never meet her provides us all with our instructions on where we’re meant to be and when. She has a phobia of people not cleaning their mugs.


Ruth Flannagan

Job Title: Accredited Coach

Ruth has taught primary kids all over Europe and as she started to settle her family back here in Bonnie Scotland chose to take her wealth of experience and insight to HeadStrong. She is partial to a cold water dip so if she invites you round for a dip in her pool we’d recommend you say no.
