For Larry Wieseneck, Head of Corporate and Investment Banking at TD Securities, the move from producer to leader is one of the most important, and most misunderstood transitions in investment banking.

Across a career spanning Salomon Brothers, Lehman Brothers, Barclays, Cowen, and now TD Securities, Larry has seen banking from almost every angle: analytics, convertibles, capital markets, strategy, integration, leadership, and firm-building.

His view is clear: the skills that make someone an elite producer are not always the same skills that make someone an effective leader. In this conversation, Larry shares what it takes to move beyond execution, build influence across an organization, develop future leaders, and create a career that compounds over decades.

Larry did not begin his career in traditional investment banking. He started in financial consulting, working with companies on strategy, valuation, and capital allocation decisions. That early exposure gave him a broad view across industries and helped him see patterns others often missed.

At a young age, he was advising companies on whether to buy, sell, invest, or grow. When he later moved into investment banking, that pattern recognition helped him work across financial institutions, defense, consumer products, and other sectors. The lesson is clear: variety early in your career can create judgment later.

One of Larry’s defining strengths has been taking complex ideas and making them understandable to clients. In capital markets, particularly in convertibles, technical ability matters. But technical ability alone is not enough.

At the highest level, everyone is smart. Everyone has acumen. Everyone has worked hard to get into the room. What separates the best from the rest is the ability to communicate clearly, motivate others, and translate complexity into something the client can act on.

For Larry, that means understanding the client’s context. A CFO who grew up in treasury may see a transaction differently from a CEO who came through operations or a leader who spent their career in business development. The advisor’s job is not to use their own language. It is to speak in the client’s language.

That is not dumbing things down. It is empathy. Great bankers understand where the client is coming from, then frame complex decisions in a way that helps them make better choices.

Larry describes convertibles as one of the best training grounds in banking because they touch almost every part of the platform. A convertible bond sits at the intersection of credit, equity, derivatives, accounting, tax, legal structuring, and market execution.

That means a young banker in convertibles has to understand investment grade debt, high yield, equity markets, research, sales and trading, volatility, derivatives, and structuring. It creates a broad technical base and a broad internal network.

For Larry, that second part mattered just as much. Running convertible origination at a young age exposed him to the leaders of high yield, investment grade debt, DCM, equities, research, derivatives, and trading. He learned not only the products, but how the institution worked.

Delivering the firm is not just about knowing what the firm can do. It is about having the relationships and influence to bring the right people together.

One of Larry’s strongest insights is that many top producers assume the next natural step is management. But being a great banker and being a great manager are not the same thing.

In banking, the transition can be abrupt. A banker may spend years producing, executing, and owning client relationships, then suddenly become a group head responsible for people, expenses, culture, resource allocation, and the P&L. Many struggle because they have not had enough steps along the way to build the management muscle.

Larry contrasts this with sales and trading, where the progression is often more gradual. A strong salesperson may first manage a small pod, then a broader sales team, then eventually a larger business. Banking does not always create those intermediate steps.

That matters because management changes the source of your success. As a producer, your outcomes are tied closely to your own client work. As a manager, your success depends on whether others succeed. That shift can be uncomfortable for people who have built their identity around personal production.

Larry is careful to distinguish between leadership and management. You can be a leader without being a manager. You can mentor people, set standards, build followership, and have a major impact without wanting responsibility for expenses, staffing, and business administration.

But if you want to be a great manager in banking, you need both. You need the values, credibility, and followership of a leader, and you need the practical skills of management.

That also means understanding what your organization actually values. Some firms are highly individualistic and production-driven. Others place more emphasis on culture, collaboration, and how results are achieved. Not every great banker needs to run a business. Some should remain outstanding producers and leaders. Others should step into management. The key is knowing the difference.

For VPs and Directors, Larry’s advice is practical. First, take inventory of what has got you to this point. Then ask what the firm actually measures on the path to MD.

Usually, the next step is moving from executing work to running teams that execute work, then eventually winning business and delivering the full organization to clients. To make that transition, you need leverage. That means developing associates and analysts so you are not trapped in every detail of execution.

It also means building influence beyond your direct team. Legal, compliance, risk, technology, product partners, and support teams all matter. Larry encourages aspiring leaders to do a 360-degree review of their areas of influence. What do you control? What can you influence? What is outside your control?

Then focus your energy accordingly. Drawing on The 7 Habits of Highly Effective People, Larry’s message is simple: spend your time on what you control and what you can influence. Do not burn energy on what you cannot.

At Lehman, Larry saw how deliberate leadership development could shape an organization. The firm invested in education around leadership, management, cultural norms, and decision-making. The goal was to create a common framework for how the firm operated.

One of Larry’s most powerful tools for identifying future leaders came through task forces. When he and a partner were asked to help integrate debt capital markets, equity capital markets, and financing into one global capital markets platform, they created task forces to examine key issues across businesses and control functions.

The output was useful, but the bigger insight was unexpected. Some people mailed it in. Others leaned in. They loved the intellectual challenge, built relationships, influenced colleagues, and helped the organization think better. Those people revealed themselves as future leaders.

Larry has used the same concept ever since. Task forces create a natural environment where leadership traits show up: curiosity, collaboration, execution, influence, and the ability to work beyond your own narrow area. The real value is not just the answer to the task force question. It is finding the people who can help run the business five years from now.

Larry has lived through two major integrations: Lehman into Barclays and Cowen into TD Securities. The circumstances were very different, but the lesson was similar.

Successful integrations require leadership teams that are committed to what is best for the institution, not what is best for individual legacy teams. After Barclays acquired Lehman’s North American operations, Larry saw leadership choose the best people for the right roles, regardless of whether they came from Barclays or Lehman. The same principle has shaped the TD and Cowen combination.

The best integrations take the strongest parts of both organizations and discard what does not serve the future. They do not become jersey contests. They become opportunities to build something better than either firm could have built alone.

When asked what separates people who compound over decades from those who plateau, Larry is direct: plateauing usually comes from lack of growth.

A firm can provide opportunities, but you cannot outsource ownership of your career. Larry believes you should think of your career as a partnership with your organization, but you own the 51% vote.

That means owning your networking, your skill development, your exposure to new products, and your willingness to raise your hand. If you are not being challenged, you need to notice. If you have not done enough M&A, LBOs, capital markets, or client work, you need to know that before the firm does.

The people who keep compounding are those who keep growing. They build versatility. They stay curious. They take on new challenges. They avoid becoming so narrow that a market shift makes them less relevant.

Larry Wieseneck’s career is a reminder that investment banking success compounds through range, judgment, communication, and ownership.

The best bankers do not just execute. They translate complexity. They build internal and external networks. They learn the full platform. They take responsibility for their growth. And when they step into leadership, they understand that success is no longer just about their own production.

For VPs, Directors, and aspiring MDs, the message is clear: be excellent at the job in front of you, but do not stop there. Build leverage. Expand your influence. Seek variety. Learn the institution. Own your development. And focus your energy where you can control or influence the outcome.

That is how a career compounds.
