Our Team

Mark is a NYC-based technologist with 20+ years leading enterprise-scale transformation. He's delivered multi-million-dollar efficiencies by turning complex, multi-year programs into rapid wins—leading teams of hundreds through migrations that cut timelines by 80% and saved tens of millions. A certified PMP and Scrum Master with deep expertise in AI and emerging tech, Mark knows how to de-risk execution and scale impact.

Mark built TendTo after managing his father's care remotely and realizing caregivers deserve better than spreadsheets and chaos.

When he's not coding, he's writing stand-up comedy.

Natalie is a product and technology executive, partner, and mother who has spent her career building systems that bring clarity to complexity. She previously served as Chief Product Officer at OTG, a multi-billion dollar hospitality and technology company, where she led the development and scaling of a multi-product ecosystem powering commerce and operations across major global airports.

After navigating the realities of caregiving in her own life, Natalie saw firsthand how fragmented, overwhelming, and invisible that work can be. She co-founded TendTo to change that — bringing the same level of sophistication, structure, and intelligence she developed in large-scale systems to one of life's most personal challenges.

Her work sits at the intersection of technology and humanity, grounded in a simple belief: the most important problems, the ones closest to home, deserve the most thoughtful solutions.

Paul Siebold is a marketing, PR, and communications executive with 20+ years building brands across media, real estate, and entertainment. As founder of OFF OFF PR, he's secured coverage in The New York Times, New York Post, NBC, FOX5, and Playbill.

Previously having led national multi-channel strategies at major radio networks and top real estate firms, Paul brings proven expertise in brand storytelling, media relations, and go-to-market execution to TendTo—reaching the millions of caregivers who need it most.

When he's not landing headlines, he's gardening and playing with his dog Luna.
