Renee Arceo

Communications Officer

Renee Arceo began her career as a talented menswear designer however sought more from life when her father passed away from early onset dementia in June 2012 at the age of 66.  Seeing first hand the effects dementia has on the person living with it and on their loved ones, Renee wanted to make a difference and help improve the lives of people affected by this disease.

And so she made the bold move and began volunteering for the National Dementia Action Alliance, a campaign she wanted to be a part of after seeing the brilliant work they were doing.  Her passion for the cause shone through and she was snapped up to work full time on the Alliance.

Her time as a designer has proven very useful and so she leads on all design work to promote the NDAA brand, as well as all its joint work programmes. She is also responsible for building the NDAA online community and is constantly maintaining, updating and developing the website to meet the needs of its members.
