Why Work with Us

At The Rittenhouse Group, your priorities become our priorities. We leverage our decades of experience, along with the premium resources of Morgan Stanley, to create a comprehensive wealth strategy that is uniquely yours.

Our priority is to help you prepare for all of life’s milestones and be your first call for any financial matter – no matter how simple or complex the situation.
Collaborative Approach
The diversity of our backgrounds, experience and areas of specialty enable us to deliver fresh ideas for today’s complex world. We are available to work with your accountant, attorney and other professionals to build a comprehensive and cohesive plan that encompasses all aspects of your life.
Concierge Service
We recognize every client is unique. Some desire in-depth explanations of investment concepts, while others understand those concepts thoroughly and prefer advisors with whom they can formulate strategies. We are committed to helping you achieve your goals in a manner that aligns with your expectations of a concierge experience.

Working with You

Our process begins and ends with listening. We ask questions about what is important to you, your family and your legacy . . . and then we listen. Through each step, we provide objective advice and investment insights to construct a wealth management plan that is uniquely yours.
Step 1: Initial Conversation
We begin with an informal discussion to understand your financial concerns and determine how we can add value. This is your opportunity to interview us, as we get to know you. If we agree to move forward, we’ll schedule our next meeting and request important financial information.
Step 2: Discovery Meeting
We continue the dialogue by fostering an in-depth conversation where we learn about the values that shape your decisions and identify any unique circumstances. We also review the documents you’ve prepared and begin to define your priorities.
Step 3: Analysis and Strategy Development
Here, we utilize proprietary financial planning tools to develop a personalized and detailed strategy with recommendations to help you grow, preserve and transfer your wealth. This serves as the foundation for building your initial plan, as well as future investment decisions.
Step 4: Recommendations and Implementation
In this step, we present appropriate investment options that, once executed, are designed to work together cohesively to achieve your goals. Upon your approval, we execute each recommendation and begin to implement the wealth management strategies we’ve discussed. These often encompass risk management, as well as estate, trust and philanthropic planning.
Step 5: Ongoing Stewardship
Committed to a concierge client experience, we focus on developing a relationship that provides special value to you and your family. As we execute each strategy, we’ll set up tools so you have immediate access to your account information. And because markets and personal needs evolve over time, we’ll schedule regular calls and meetings to ensure your plan remains on track to achieving your goals.

Personalized Solutions

While the strategies we provide are broad in scope, our approach is one hundred percent individualized. We deliver the personalized attention you expect, as we build a structured plan focused on achieving your financial and legacy goals. Here is a brief overview of the solutions we offer:
Lifestyle Management
We pay particular attention to the timing of milestone events to help ensure you are prepared each step of the way. Whether you are planning for your children’s education, a comfortable retirement or the sale of your business, we develop the strategies needed to achieve your goals on schedule.
Family Finances: A Conversation Guide
Asset Growth and Preservation
Asset management aims to achieve the best possible returns consistent with your level of risk. Working together, we create a customized strategy that applies long-held investment principles to help your assets appreciate appropriately. We also welcome the opportunity to incorporate sustainability, environmental and social values into our process.
Financial Literacy for Any Stage of Your Life
Longevity Planning
Given extended life expectancy, we help customize allocation and distribution strategies to help you preserve assets, whether they are held at Morgan Stanley or other firms. This includes advice on 401(k) plan assets, life insurance, long-term care plans and lifetime income strategies.
Retirement Lifestyle: What Kind Do You Want?
Risk Management
Life’s risks can manifest themselves in many ways – from loss of life to loss of health – and have the potential to impair the efficiency of a thoughtfully developed plan. We help address these concerns in a number or ways, ranging from insurance reviews to liquidity strategies.
Morgan Stanley Risk Platform Video
Legacy Planning
Delivering an estate to the next generation or favorite charity requires more attention than families often realize. Coordinating with outside estate and tax professionals, we align estate planning goals with the appropriate asset titling and beneficiary designation requirements, while incorporating best practices to help enhance results.

3The returns on a portfolio consisting primarily of Environmental, Social and Governance (“ESG”) aware investments may be lower or higher than a portfolio that is more diversified or where decisions are based solely on investment considerations. Because ESG criteria exclude some investments, investors may not be able to take advantage of the same opportunities or market trends as investors that do not use such criteria. Diversification does not guarantee a profit or protect against loss in a declining financial market.
