Meet the Team
Colin Marshall
Driven by a desire to travel, I began freelancing as a writer, web designer, and SEO specialist.
After 6 years of freelancing for clients in the US and around the world, I started Portal Marketing in an effort to connect with local clients in Charleston, SC and Greenville, SC.
I particularly enjoy helping our local clients grow their businesses and build their local communities.
However, I still take on global projects for clients seeking creative design and handcrafted content.
When I’m not working, I enjoy hiking with my dogs, producing music, training in the gym, and nature photography.
Yesica Castrejon
I grew up helping my immigrant family manage and grow their businesses.
At a young age, I learned how to build and lead a team and how to use creative marketing to help them bring in new customers and clients.
I’m a painter, visual artist, and graphic designer by trade.
I handle social media marketing and branding for Portal’s clients. I love helping small businesses develop their unique brand image and creating innovative social media marketing strategies that fit their brand.
Outside of working with our clients, I enjoy painting, walking through nature, and watching live music.
