A guide to your first 90 days in a senior law firm marketing role

The first 90 days in a senior marketing or BD role at a law firm will shape how partners perceive marketing for years to come. This window influences much of how leadership engages with growth conversations, the breadth of your remit, and how confidently your team performs under your direction.

Law firms are distinctive environments for marketing leaders to navigate because influence is earned through trust and commercial understanding, rather than seniority or title. Decisions tend to form through conversation and consensus before they ever reach a formal agenda, and relationships sit at the center of everything, including revenue, reputation, and long-term stability. Getting to grips with how that operates in your firm requires careful planning.

Start with understanding

The temptation in any new leadership role is to demonstrate value quickly. In a law firm, moving too fast before you understand the room is one of the most common mistakes senior marketing leaders make.

Your first 30 days are best used for building an accurate picture of the firm: where revenue comes from, which clients and sectors matter most, how work originates, and where the informal influence sits regardless of what the org chart says. That means planning structured conversations with managing partners, senior leadership, practice group heads, your own marketing and BD team, and operational leaders in finance and technology. You should also spend a good amount of time reviewing your firm’s financial performance, auditing the website, and taking a hard look at CRM data quality and usage patterns.

By the end of the first month, you’ll have built a strong foundation if you understand your firm's commercial drivers, which relationships matter most internally, and an initial idea of how to drive growth.

Creating visible progress

By the time you reach your second month, the initial curiosity from partners and leadership tends to shift into expectation.

Despite this shift, trust is still being established, and big strategic changes introduced too early tend to create resistance before you have the credibility to see them through. The goal for your second month should be a few small concrete wins that partners will notice, like strengthening a live pitch that converts into new work, fixing a broken process that’s been frustrating the team, or turning a recent webinar into content that drives follow-up.

This phase is also when you can start leading your team more deliberately. Many law firm marketing teams have operated for years without clear KPIs or meaningful accountability structures. Introducing that gradually, without overwhelming people who are still adjusting to new leadership, builds the internal foundation you’ll need later when you’re ready to push for broader change.

Setting direction

By your third month, you’re no longer new. The firm has seen how you think and engage, and you have the credibility and evidence to start shaping new initiatives.

This is when you should start defining a clear growth plan for the firm, covering revenue growth sources, new processes and projects you plan to implement, and key stakeholders required. You should be as specific as possible with your plans, as partners rarely support vague commitments to raising the firm's profile.

Your third month is also when you can start thinking about the martech and infrastructure you’ll need to achieve your goals. Many law firms lack consistent visibility across client relationships and pipeline; 72% don’t measure client churn, 83% don’t track marketing ROI, and 24% don’t track revenue growth. Without shared data and reliable relationship intelligence, growth depends heavily on individual memory and informal communication. Making the case for better systems at this stage works best when you lead with the business problem rather than the technology solution, i.e. which clients are at risk, what opportunities are being missed because no one has a full picture of who knows whom, and where leadership is making decisions without the data they need.

By the end of your third month, you should be ready to present your findings and a 12-month roadmap to leadership. A structure that tends to land well with leadership covers the firm's current position, your key observations from your first 90 days, and your proposed direction. Getting key stakeholders aligned before that presentation, rather than using it as the moment to introduce your thinking, will significantly improve your chances of getting the support you need.

What comes after the first 90 days

By Day 90, the firm has formed a view of you and your function. What you do next will determine how far your influence extends. Marketing leaders who earn lasting influence at law firms are the ones who make partners more successful. Over time, they become the leaders partners turn to for growth decisions, speaking in commercial language and building a function the firm comes to rely on. That kind of influence is built over years, but if you lay the foundations now in your first 90 days, you’ll set yourself up for success in the future.
