A Note From Sandy 


Sandy Stewart
Founder, Think Big

My name is Sandy Stewart, and I'm a Social Impact Strategist, Carbon Footprint Specialist, and Value Growth Expert. I'm the founder of Think Big, a strategic sustainability agency that helps businesses create and sustain value growth while implementing sustainability initiatives.


I have over 20 years of experience working with SMBs and SMEs, first as a Business Coach and then further specialized as a Value Growth Trainer & Consultant. In addition, I earned the Sustainable Leadership Institute Certification from the University of Cambridge, as well as Shirlaws Coaching certification and a CoachU Graduate certificate. 

My mission is to help 1m businesses grow their sustainability efforts. Whether you start with climate impact, social impact or company value growth, the most important step is the first one. 


Together we can make a difference.

Why become a Sustainability Leader?

You want to know how to future-proof a company

Given the pace of change with public policy, consumer buying trends, younger labor force, Scope 3 trickle-down effect (ask me about this one!) and raw material volatility, every business will feel the pain of at least one or more of these. Whether it’s this year, next year or 3 years from now, it’s not a question of ‘if’, it’s a question of ‘when’. 

You want the competitive edge

Knowing that eventually all businesses (in ALL industries) will transition to sustainable practices including social good and and/or a net zero path, being one of the first in your field will solidify your brand ‘on the leader board’. Plus, waving your sustainability flag attracts top talent making hiring easier and faster.

You want to make a big positive impact on the world

Let’s face it. Your pioneering passionate spirit is not going to stop you from making a positive impact and paving the way for others to follow. You want to create impact by shrinking your footprint, going circular, using sustainable partners or activating leadership in your communities. Maybe all the above!  

Why are you waiting?

"Our company is too small to make a difference"

No business is too small to start. Becoming a Sustainability Leader will put you in the driver's seat to lead any company to becoming a thriving sustainable brand. 

And with over 30million small businesses in the US, as a Sustainability Leader, you can join the movement to be a small business front runner.

“We already sell a sustainable product, so we don't need to build sustainability in our operations too”

     Yesss! So happy to see so many new sustainably designed offerings everywhere. But even companies built around a sustainable offering should ALSO look at instituting sustainability.


As conscious consumerism grows, so does the need to 'walk the talk'. In fact, it’s your best way of promoting what you believe in!

"You are going to learn things that you would never even think to try to learn, because you don't know what you don't know.  If you’re really good at your skill, but you’ve never run a business before, I don’t know how you’re going to sustainably grow your business without doing something like Think Big."
