Mark Casali
Mark partners with clients to design, implement, and optimize lead-generation and customer-acquisition strategies that drive measurable growth.
Before founding Synapse, he worked as a Certified Public Accountant, providing audit, tax, and consulting services across manufacturing, retail, and non-profit sectors; experience that continues to inform his analytical, business-first approach to performance marketing.
With 15+ years in SEM and SEO, Mark has helped grow Synapse into a successful agency serving 40+ clients with a team of more than 15 professionals. He has spoken at multiple industry conferences, and his development of a proprietary SEM statistical analysis suite was published in Search Marketing Standard.
Outside the office, Mark is an avid fly angler, chasing trout on the Farmington River, stripers and albies in Long Island Sound, and tarpon in the Florida Keys. A longtime fly-tyer, he currently serves as Treasurer of the Connecticut Fly Fisherman’s Association.
