Russell Greenstein

Chief Revenue Officer

Russell Greenstein is Co-Founder and Chief Revenue Officer of MileMark, a digital marketing agency that works exclusively with law firms. He co-founded MileMark in 2014 with a clear purpose. Large legal marketing companies weren’t offering the attention or flexibility firms needed. Small general agencies didn’t understand the complexities of marketing a law practice. MileMark was built to close that gap. Since then, Russell has helped grow the company into a six-time Inc. 5000 honoree, recognized among America’s fastest-growing private companies.

Russell has spent more than 25 years in digital marketing. Before MileMark, he spent over 11 years at LexisNexis Martindale-Hubbell and AT&T Interactive. There he built a track record helping attorneys and small businesses improve performance across SEO, paid search, social media, directories, and email marketing. That experience gives him a long view of how law firm marketing has evolved, from directory listings to search engines to today’s AI-driven platforms.

Today, Russell leads MileMark’s new business development, so he is often a firm’s first conversation with the agency. He has partnered with hundreds of law firms nationwide, from solo practitioners to multi-office practices, helping them generate high-value, profitable cases. His approach is consultative and diagnostic. He works out where a firm’s cases actually come from and what is limiting its growth, then builds a strategy around measurable results rather than vanity metrics.

Russell is a leading voice on how law firms should adapt to AI search. Potential clients increasingly find lawyers through ChatGPT, Claude, Grok, Google AI Overviews, and similar tools. He helps firms position themselves to be cited and recommended by those platforms, not just ranked in traditional search results.

Russell is also an owner of Attorneys.ORG, a national legal directory connecting consumers with more than 250,000 attorneys across 100 practice areas. The directory gives him a direct view of how people search for and choose a lawyer, and that insight shapes the strategies he brings to MileMark clients.

He is a frequent speaker on cutting-edge legal marketing strategy, law firm web design, and the role of artificial intelligence in the legal industry. Russell studied Business Management and is a Strategic Member of the Florida Lawyers Network. He is Google Certified and a SEMPO Certified Online Marketing Expert.

Russell serves on the Board of Directors of Busch Wildlife Sanctuary, a nationally recognized leader in wildlife rehabilitation, conservation, and environmental education.
