Our team is made up of creative business professionals who have a deep, vested interest in the world around them, and who feel a responsibility to make the world a better place. We believe that through promoting people-based businesses and the grassroots work of dedicated nonprofits, we are doing our part to live up to that responsibility. While our motivation is derived from this sentiment, our work arises out of deliberate, technical skill: intelligent strategizing and analysis, purposeful design, and thoughtful copywriting.   


Founder & CEO

I love strategy and always see the big picture. From a young age, I understood the way systems work and sought to improve the status quo. I have traveled and volunteered extensively throughout Europe and India, beginning with my first trip at age 7. These global experiences have inspired a lifelong mission to do meaningful work. I started Green Gate as a way to marry my love for branding and marketing with service to the greater community.

As founder and CEO of Green Gate, I guide the vision and oversee our client relations, business development, and marketing strategy. I’ve built an approachable, people-centric agency, powered by a handpicked team of talented creatives. In 2017, Green Gate took home 21 awards for our work, including a Regional Design award in the prestigious PRINT magazine. In 2018, we’ve won 8 awards to date, including an AMY award for visual brand identity.

Over the course of my career, I have worked in marketing and advertising across multiple industries including healthcare, technology, travel, hospitality, and the nonprofit sector. I create marketing and branding strategies that connect with customers, build relationships and produce results. As marketing director of the Chai Pani restaurant group, I helped expand to the Atlanta market and launch the opening of two new restaurants to great success, garnering hundreds of press mentions, and increasing annual revenues by more than 400%. My work has been recognized multiple times by the AAF and, in 2012, I was invited to attend GIGTANK, a competitive business incubator for tech startups.

Through Green Gate, I have been able to donate close to 3,000 pro bono hours to local nonprofits.  I am on the board of directors at Raising Expectations, InwardBound Center for Nonprofit Leadership, and Stride Ahead and have volunteered for Emmaus House, Habitat for Humanity, The Learning Tea, The Meher Spiritual Center, The Rotary Club, and the Posse Foundation as a career coach. I am personally inspired by courage, kindness, and golden retrievers.
