“Don't let aging get you down. It's too hard to get back up” – John Wagner


Liz Grantham

Our Founder

Liz GranthamLiz has over 30 years’ experience in marketing & advertising providing innovative, integrated, thoughtful solutions for global clients like Visa, Shell and Sony Mobile, working on various projects including the Olympics.

Her love of a challenge and making BIG things happen, together with a need to manage the stress that comes along with running a business, endless deadlines, keeping clients happy, being a present and mindful mom – led her on the journey to what has become “TheOptimal.me”. This is her greatest challenge yet!

“I believe that all the hard work, experience, and endless curiosity, together with the need to not only survive but thrive as I get older, has led me to this point. The joy of finding long term solutions to feeling even better and being excited about what’s ahead is just something worth sharing … and so that’s exactly what I’ve done!”
