Sara Guida has spent over 30 years in B2B sales and marketing, including national account leadership and two decades running her own businesses. Together with her husband, Steve, they run Prestige Delivery Service, Inc., and in the last several years she started Sara Guida Agency, also known as Aging Parent Resource Center. Running these businesses is where she first learned to operate a business on HighLevel, long before it became the platform behind SilverCore.

She started SilverCore.io in December 2025 out of her own need. After three decades in sales, she had never once owned her own system to track a contact or a conversation. Every job came with someone else's CRM and someone else's tools, and none of it went with her when she left. So she built her own.

That system turned into a way to help other business owners solve the same problem. Today Sara runs SilverCore.io as a full-service marketing agency and fractional CMO, built for owners who need a real system behind their business, run by someone who actually knows how to use it.
