Sequent provides Family Office Wealth Management, Investment Management, Financial Counseling,
and Portfolio Consulting and Fiduciary Coordination services to individuals, including closely held
business owners, senior corporate executives, retirees, trusts, estates, charitable organizations and
corporations or other business groups.
Traditional Advisory Business
As a comprehensive multi‐family office, we provide advice to families who have, had or will have their
own business. Be it a multi‐generational family owning and running a closely held business or a high‐
ranking corporate executive of a publicly traded or privately held company or a professional with their
own practice; our differentiation is not in what we do, but rather what our clients do and how we help
them do it better. We help families at key financial crossroads in life, such as births, deaths or divorces,
starting a business, retirement, selling a business, etc.
Investment advisory, personal and business financial counseling services are provided to high‐net‐
worth families, trusts, estates and charitable organizations, corporations or other business entities.
Investment advice, financial counseling and comprehensive portfolio management services are
provided on a continuing basis. The Firm has provided these services since 2008.
For each client family, we review their goals and objectives, their specific concerns and risks and
their assets and earnings, and from this personal data, an allocation strategy and personal financial
plan is custom designed, recommended and implemented. We provide a holistic service approach
that includes:
(1) Family Office Wealth Management Services
Sequent’s family office is a holistic wealth management solution. Our services include a
comprehensive review, analysis, and recommendations combined with the ongoing management for
a family’s accumulating wealth in any type of account (personal, trust, retirement, charitable, etc.) to
include asset allocation determination (by account and overall) and tactical adjustments to specific
investment holdings over time in keeping with lifestyle changes and prevailing or anticipated
economic and market conditions. Sequent’s family office management services include review,
analysis, and recommendations across the seven key areas of a family’s personal financial situation:
(1) Balance Sheet; assets and debts, (2) Cash Flow; income and expenses, (3) Accumulation; savings
for retirement, college funding, etc., (4) Insurance, (5) Tax; income, capital gains, business, gift and
estate, (6) Estate & Gift planning, and (7) Business/Succession planning.
(2) Investment Management Services
Sequent provides investment management on a stand‐alone basis, upon request, to meet client
requirements. Fees are negotiable. This service offering entails a detailed, fiduciary–based investment
process centered on an investment committee format.
(3) Financial Counseling Services
Sequent provides financial counseling services on a stand‐alone basis, which include review, analysis
and planning recommendations provided across any or all of the key areas noted above.
An Overview of the Firm
Sequent was formed in 2008 as a multi‐family office and professional investment management firm
dedicated to serving a select number of client families and their needs. Sequent is directly owned
by Hartzell, LLC, and MadsenWaters, LLC. Tim Hartzell and David Doll are Managing Members of their
respective limited liability companies. As partners, we decided early on that what we were seeking
to create was a boutique firm, a firm focused on serving highly ranking corporate executives,
professionals and families that have, had or will have a closely held business. We have also responded
to the request from peer firms to offer parallel services to support their firms and maximize
efficiencies. Having spent time at large organizations, we were well aware of the distractions that come
with managing a large staff along with overseeing the company itself.
We decided to be selective with those that we work with, ensuring for our client families that our
differentiation would truly be not what we do, but rather what our clients do and how we help them
to do it better. We strive to provide client comfort and trust by being more intimate, and more
connected with each family, avoiding the normal dilution that occurs as a firm/individual grows
in clients and accounts. We travel extensively to know and be a part of our clients’ lives, working
with over thirty families in over a dozen states and several countries. Sequent partners have
considerable international experience in helping families and executives with investment and
business activities from the US to Europe, Latin America and the Far East.
Why Sequent? Quite simply, our experience and commitment focus is on serving families that have,
had or will have their own business. Forged through decades of working exclusively with closely held
business owners and high‐ranking corporate executives, we have a body of knowledge and deployable
skill sets in the areas that most impact the accumulation and transfer of wealth for our client
families.
As a comprehensive multi‐family office, we dedicate ourselves to providing custom tailored and client
specific solutions for our families. We help families to focus on maximizing and balancing personal
and corporate investments and developing replacement cash flow and liquidity. Additionally, we help
coordinate business leadership transitions along with wealth transfers from one generation to the
next and optimizing financial decisions to mitigate the impact of current and future taxation on a
family’s wealth.
Sequent partners are involved with each client, providing the wealth of our multi‐disciplinary
talents across each family’s needs. We keep administrative costs and distractions to a minimum by
being selective in the type of client families we serve. This allows us to spend more time focusing
our attention on our clients’ financial affairs. Our services are much broader than financial planning,
investments, and fiduciary account management. We seek to serve as a family’s personal chief
financial officer to both recommend and coordinate matters important to them. We utilize a proven
process honed over time that focuses on cash flow as the bedrock element in long‐term financial
success and comfort for each family.
As a fee‐only family office firm, the only revenue earned by our firm is fees paid to us by our client
families or by firms that seek our investment / counseling advice.
