About
The people behind the plan.
P5 has done marketing since 1996. Today we run search, ads, audiences and tracking for owner-operated businesses, one tool at a time or as your Marketing Quarterback. Every month you get one plan, an action list for each vendor, and a scorecard that tracks the numbers that matter. We stay accountable to the number you care about: paying customers. Plastic surgeons work with our dedicated practice at p5marketing.com.
A senior team, not an account hierarchy.
The people on this page are the people who do the work.
Co-Founder · Strategy & Operations
Robert Donnell
Robert has spent twenty-five years running marketing for service businesses, from surgeons and law firms to wedding venues and travel. He leads strategy, client relationships, and the overall direction of P5, and personally owns the senior strategic work on every account. He built the in-house toolkit P5 uses to measure the work, including IntelID, SEO/AEO, IntentID, VisitorID, and InboxID. When a client asks who is accountable for the plan, the answer is Robert.
Marketing · Social Media, SEO & AI Optimization
Irene Donnell
Irene leads P5's digital growth strategy across social media, SEO, and AI optimization. She works at the point where visibility becomes revenue, making sure clients show up where their customers are actually looking, from Google to the AI answers that increasingly replace it. Her work attracts qualified leads and converts attention into measurable growth. If a client is being found, followed, and chosen online, Irene is the reason.
Chief AI Officer
Sean Carlos Fleming
Sean has spent his career building what doesn't exist yet. He founded a digital and social analytics practice from the ground up at a time when the field was still taking shape, developing new methods and leading the teams that ran them. His instinct has always been to look ahead, to see where technology and consumer behavior are going and get there early. As Chief AI Officer at P5, Sean is doing it again, launching a new offering that expands the company into an entirely new line of business.
The team that runs the work
Camilo Contreras
Lead Developer
Camilo builds the technical infrastructure behind every campaign: landing pages, CRM integrations, tracking systems, and automation workflows. If it touches code, Camilo built it.
Arlet Gutierrez
Campaign Operations
Arlet manages day-to-day campaign execution: ad builds, audience uploads, reporting dashboards, and QA. She keeps every moving piece on schedule and on spec.
Adrianne Panza
Client Success & Onboarding
Adrianne is the first person new clients work with. She handles onboarding, CRM setup, and ongoing communication to make sure every client knows exactly what is happening and what is next.
Advisors
Senior counsel behind the scenes.
Stephie Althouse
Advisor · Process & Knowledge Systems
Stephie holds a PhD in chemistry and began her career leading advanced R&D programs, including DARPA-funded land mine detection work. For the past two decades she has helped expertise-driven companies capture the knowledge that lives only in a few people's heads and turn it into systems the whole team can execute. At P5 she keeps our process documented, repeatable, and never dependent on any one person, which is what our clients depend on us to provide.
Joely Gardner
Advisor · Usability & User Research
Joely is a PhD psychologist with more than twenty years of human factors and usability research for companies from single-device startups to Philips Healthcare, Olympus, and Sony, plus thirteen years teaching user experience at Cal State Fullerton. At P5 she pressure-tests the pages, forms, and funnels we build so the experience is effortless for the customer on the other side.
