Investment Services Group

What Investment Services Group does

Investment Services Group (ISG) is an independent financial advisory firm headquartered in Grand Rapids, Michigan, that provides personalized wealth management and financial planning services to individual investors. The firm operates a relationship-driven advisory model structured around a four-step engagement process — initial conversation, assessment, customization, and ongoing connection — delivered through a small team of dedicated advisors rather than a digital platform. ISG is independently owned by the Brown family (Michael W. Brown and Matthew W. Brown), with Karen Droste managing client communications since 2004.

ISG's service offering spans financial planning, investment management, retirement planning, tax planning, estate planning coordination, and budget and cash flow management. The firm delivers broker-dealer services through a core partnership with LPL Financial and registered investment advisory (RIA) services through Private Advisor Group, enabling it to offer the full spectrum of securities and investment products without proprietary product conflicts. ISG maintains no proprietary technology platform, no mobile app, and no public API; service delivery is human-advisor-led, supplemented by a content blog dating to 2019, email outreach, and a Facebook presence for top-of-funnel acquisition. Revenue is generated through recurring advisory fees on the RIA side and transaction-based compensation on the broker-dealer side, with pricing not publicly disclosed.

The firm serves individual investors across multiple life stages — including those navigating life events such as divorce, marriage, retirement, and inheritance — with a particular focus on pre-retirees, retirees, and healthcare professionals. ISG is registered to serve clients across ten U.S. states (AZ, CT, FL, IN, MA, MI, NC, NY, OH, VA) from its single Grand Rapids office. Customer concentration is inherently high given the lifestyle practice model, with revenue tied to the relationship capacity of two named advisors and an undisclosed client book.

Direct peers

• Savant Wealth Management: Independent, fee-based RIA offering comprehensive financial planning, investment management, tax, and retirement services to individuals. Highly comparable as an independent multi-advisor firm competing for the same mass-affluent and pre-retiree segments that ISG targets.
• Carson Wealth: Independent wealth management firm delivering financial planning, investment management, and retirement strategies to individuals and families. Comparable in that it operates as an independent advisor group with a similar planning-led GTM and mass-affluent client focus.
• Merit Financial Group: Independent RIA providing wealth management, financial planning, and retirement income strategies to individuals. Comparable as a mid-sized independent advisory firm with the same fee-based RIA structure and planning-centric offering.
• Wealth Enhancement Group: Independent wealth management firm offering financial planning, investment management, and tax services through a national advisor network. Comparable independent RIA model targeting the same mass-affluent and pre-retiree segments through advisor relationships.
• Edelman Financial Services: Large independent RIA providing fee-only financial planning, investment management, and retirement planning to individuals nationwide. Closely aligned in business model — independent, fee-based, planning-led — but larger in scale than ISG.

Regional players

• Commonwealth Financial Network: Independent broker-dealer and RIA platform that supports independent advisors like ISG with custody, compliance, and product access. Comparable because ISG sits on a similar IBD/RIA platform stack (LPL/Private Advisor Group) and competes for the same end-client relationships.

Broad incumbents

• Cetera Financial Group: Large independent broker-dealer and RIA platform serving thousands of independent financial advisors. Comparable as a broad incumbent in the same independent-channel ecosystem in which ISG operates, though significantly larger and broader in scope.
• LPL Financial: ISG's own broker-dealer partner and the largest independent broker-dealer in the U.S. Comparable as the incumbent infrastructure provider in ISG's value chain — LPL-affiliated advisors pursue the same mass-affluent clients with similar planning-led offerings, and represent both a partner and an indirect competitive channel.
• Fisher Investments: Large independent money manager providing discretionary portfolio management and financial planning primarily to high-net-worth individuals. Comparable independent-ownership narrative and retail-focused distribution, though materially larger and more institutionally oriented than ISG.

Emerging players

• Personal Capital (now Empower Personal Dashboard): Digital-first wealth manager combining a free financial planning dashboard with fee-based advisory services for mass-affluent and HNW individuals. Comparable as a competitor for the same mass-affluent retail client, but differentiated by a tech-led delivery model that contrasts with ISG's traditional human-advisor approach.
