About

I’ve spent the past decade in B2B sales, lead generation, and appointment setting with an emphasis on cold calling. In 2021, I founded LevelUp Leads to help companies remove the bottleneck in their revenue engines by delivering predictable, qualified pipeline opportunities. At LevelUp Leads, we partner with B2B companies who are stretched thin on bandwidth or lack the internal SDR infrastructure to consistently fill their sales pipeline. We act as an extension of your team, owning outbound prospecting through multi-channel outreach to book highly-qualified meetings so your team can stay focused on closing deals. Our agency is fully remote, serving clients across industries and time zones, with a mission to simplify growth without the overhead and risk of building an in-house SDR team. When I’m not coaching teams or optimizing campaigns, you’ll find me sharing insights on lead gen trends, sales best practices, and how revenue teams can build pipeline.
