Sara Guida has spent over 30 years in B2B sales and marketing. That includes national account leadership and two decades running her own businesses. She and her husband, Steve, run Prestige Delivery Service, Inc. Sara also started Sara Guida Agency, known as Aging Parent Resource Center. Running these businesses is where she learned to operate 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 owned her own system to track a contact or a conversation. Every job came with someone else's CRM and someone else's tools. None of it went with her when she left. So she built her own.

That system became 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 knows how to use it.

SilverCore is based in Council Bluffs, Iowa, and works directly with clients across the Omaha metro. The agency also serves clients nationwide.
