We are Tetley Investments

Based in Chicago, we're a different kind of financial advisory firm. Our corporate culture is what our clients love most about us because, well, it isn’t “corporate” at all. When you speak with our team or stop by our office, you’ll quickly realize how much we care about our clients and how passionate we are about managing their wealth the right way. We pride ourselves in being a true advocate and advisor to our clients, becoming an integral part of their lives and the journey they take with every milestone. Our goal is simple – to ensure our clients can enjoy all of life’s most important moments and to make sure they can get there financially.


A little history

When Phil Tetley founded Tetley Investments, he did so after speaking with countless clients and researching dozens of financial advisory firms. It wasn’t long before he realized just how “hands-off” larger firms were when it came to their clientele. After nearly 25 years in the investment advisory industry, he decided he wanted to do things differently. He envisioned a financial advisory firm where clients received true personal attention in every aspect of their relationship. It was time to make a change, and thus, Tetley Investments was born.

Here at Tetley, we believe there’s nothing more important or humbling than being entrusted to manage a client’s wealth and family legacy. It’s a calling that demands the utmost respect, which is why applying a personal approach is absolutely critical to establishing the kind of trust our clients deserve. It means personally analyzing every part of our client's financial strategy and ensuring we listen to, and find solutions for, every one of their goals. It's something larger firms aren't able to offer their clients and has since become our biggest advantage.

We're able to offer clients the personal attention and strategy larger firms cannot.

Due to the complexity of financial planning, many people have a hard time understanding the investment strategies and portfolios their financial advisors create for them. It's up to their advisor to thoroughly explain every aspect of their strategy and give them a clear picture of where they are now - and where they're headed. It's something larger firms often lack, leaving clients confused and frustrated with their financial picture. It requires a level of personal attention and care which we at Tetley Investments have perfected over the years.

At the end of the day, we’re not your typical financial services firm. We’re not some large, faceless institution, interested only in selling products instead of giving advice. Whether you already have an investment portfolio and are looking for a second opinion - or you’ve never worked with an advisor before - we’re here to help. Working with us, you'll see that the way we approach your wealth results in a very different experience than what you're used to.

Our approach to investing

For over 20 years, we’ve helped individuals, families, and businesses achieve their financial goals, no matter the size or scope. We’ve set out to change the way people engage with their financial advisor. Unlike many other wealth management firms, we’re not interested in selling mediocre financial products or giving generic advice. Instead, we're all about creating custom-tailored solutions and strategies that are as unique as the clients we build them for. We’ve been successful because we treat our clients with admiration and respect. We treat them like family.

A personal touch.

We strongly believe in taking a personal approach with every single client. It’s a concept that's deeply ingrained into every aspect of our firm - and it's something that's never wavered. We value every client, taking time to listen to their goals and recommending customized financial solutions to grow and protect their legacy. We understand that every client’s financial situation is different – just as their goals and vision for the future are unique. Our mission is helping you get there, in the best and most efficient way possible.

Our investment strategies are tailored around your goals.

We always take a very hands-on approach with every aspect of the financial planning process. We’re not here to just help create a one-time investment strategy for you. We’re also here to learn about your lifestyle and your goals for the future. With the personal relationships that we nurture, we’re able to apply custom-tailored solutions in ways you wouldn’t normally expect from a financial advisor.

We’re fiercely loyal, passionate and caring about each and every one of our clients. It’s why so many of our customers have been with us for over a decade. Our ability to provide such close, personal relationships and custom-tailored solutions is our greatest advantage - one that larger firms lack. Our clients feel comfortable and excited every time they talk with us - never intimidating or confusing. We want you to be excited about the future and everything that comes with it. No matter what your goals, we will help you find the right strategy to achieve them.


Our Philosophy

Our philosophy is simple. Watch our video below to learn more.

The journey of your life is unique and filled with excitement. Your finances should help you get there – not hold you back. Our job is to be by your side every step of the way to make that happen. We take a compassionate and personal approach to every client that works with us, taking time to understand everything you want to achieve and walking you through every part of the process. We take a long-term approach to our investments, focusing not only on returns, but the protection of your wealth as well.

Whether you have an existing investment portfolio or are just getting started, we’ll create a personalized strategy tailored to your situation. We encourage every client to stop into our office so that we can start the conversation. We’ll explain every aspect of your strategy, answer questions, or just talk with you about your goals.

We’re firm believers that knowledge always trumps firm size. We pride ourselves on being able to offer what most “big box” firms cannot – a personal strategy created solely for you and your family.

Peace of mind means having a financial advisor you can trust – and that’s been our founder’s philosophy for over 20 years. Learn more about our philosophy on our FAQ page.

Phil Tetley


Ever since he started in the investment industry back in 1993, Phil realized there was something missing. After analyzing dozens of investment firms, he came to the conclusion that many of the “big box” firms cared little about their clients. They sold products, not solutions, and often ignored the questions and concerns of their clients. As a result, Phil founded Tetley Investments, a Registered Investment Advisory firm, in 2012 so that he could do what these larger firms could not – treat clients the way he felt they deserved to be treated.

Since his founding of Tetley Investments, the firm has grown significantly, entrusted with the wealth of countless families in the Midwest, many of whom have been with Phil for over a decade.

Phil has over two decades of investment management experience at various institutions such as Northern Trust Bank and Robert W. Baird.

He is also the recipient of the exclusive “President’s Club” award for three years in a row. Phil has also received the 5-Star Professional Award for Chicago Wealth Managers numerous times.

Throughout his career, Phil has helped thousands of high net worth investors implement hundreds of millions of dollars in investment strategies.  He has counseled CEOs, doctors, business owners, law firm partners, Fortune 500 board of directors, professional athletes and some of Chicago's elite families, successfully positioning well over $400 million in investable assets.

A graduate of Illinois Wesleyan University with a B.A. in Business Administration, Phil is registered with the Securities Exchange Commission and licensed to provide investment advice in many states across the country. He has passed:

  • Investment Company Products/Variable Contracts Limited Representative and Uniform Securities Agent State Law Examinations (1993)
  • General Securities Representative and General Securities Principal Examinations (1994)
  • Registered Options Principal Examination (1996)
  • General Securities Sales Supervisor Examination (1997)
  • Uniform Combined State Law Examination (2001)

He also enjoys spending weekends with his family in central Illinois. He’s a huge fan of the Chicago Bears, college basketball, boating, and his favorite classic rock bands.

At his side is always his loyal dog Mia, a Black Labrador Retriever, who he rescued and gave the honorary title of Tetley Investments Chief Morale Officer.
