The Family Tree difference

Depth without fragmentation.

The team is designed to reduce noise—not add another layer of it. Each specialist contributes to one family plan, with a shared commitment to clarity, objectivity and long-term stewardship.

T

Tax depth

CPA-led thinking that considers the tax consequences of protection, succession, estate and cash-flow decisions together.

R

Risk intelligence

Actuarial and insurance analysis that tests assumptions, trade-offs and long-term resilience before implementation.

P

Planning clarity

Comprehensive financial planning that connects the facts, models alternatives and creates an understandable roadmap.

L

Life beyond wealth

Retirement and personal planning that asks not only whether the money will last, but what the wealth is meant to make possible.

How the team works

Personal, disciplined and coordinated.

We work with your internal team and ours to create strategies that are coordinated, tax-aware and built to last. The plan remains the common roadmap from first conversation through implementation and ongoing review.

    Discover

    We begin with deep listening—your family, business, values, responsibilities and intentions.

  2. 02

    Organize

    We build a full, honest view of your current position, risks, structures and planning priorities.

  3. 03

    Collaborate

    The right specialists and existing advisers are brought together around the same facts and direction.

  4. 04

    Design

    Tax, retirement, estate, protection and investment oversight are coordinated within the Family Tree Plan.

  5. 05

    Tend

    The plan is reviewed and adapted as markets, tax law, family dynamics and life itself continue to change.

Begin with a conversation

Build the right team around your plan.

Every family arrives with different questions, relationships and responsibilities. Our role is to listen first, bring the right expertise to the table and help create a coordinated path forward.

Mark Calla

Mark Calla

CEO · Chief Efficiency Officer · CPA, CA, CLU

Mark Calla founded Family Tree Private Wealth as an independent practice built around a simple belief: complex wealth decisions should be made clearer, more coordinated and more personal. The firm represents the culmination of more than twenty years of experience advising families, business owners and professionals across the Greater Toronto Area.

What distinguishes Mark is the uncommon combination of a CPA's tax discipline and a CLU's advanced understanding of insurance and protection planning. He considers tax strategy, estate preservation, business succession, risk management and insurance together—not as separate recommendations delivered in isolation.

Mark is recognized within the industry as a mentor and sought-after speaker. His perspective is also requested when new insurance strategies and solutions are being considered and designed. He regularly works alongside accounting firms, law firms and other professional advisers to connect each area of expertise within the family's larger plan.

Plan first. Plan only. Then—and only then—consider the solutions.

  • Tax-informed planning and strategy
  • Insurance and protection design
  • Business succession and estate coordination
  • Professional-adviser collaboration

Susan Latremoille

CRO · Chief Retirement Officer · CEPA, CPRC, FEA, ICD.D, MBA

Susan brings the human side of wealth into the planning conversation. After a 38-year career in wealth management, she co-founded Next Chapter Lifestyle Advisors to help individuals, families and business owners prepare for the personal realities of retirement, succession and life after a demanding career.

Through the Happiness Portfolio® framework, Susan helps clients plan intentionally for the non-financial dimensions of their next chapter—including purpose, relationships, health, identity, contribution and the way they want to invest their time and energy.

Her work helps families move beyond the question “Will the money last?” to consider a deeper one: “What is this wealth meant to make possible?”

A successful retirement is not only funded. It is intentionally lived.

  • Retirement lifestyle planning
  • Purpose and identity transitions
  • Family conversations and next-chapter design
  • Happiness Portfolio® planning
Scott Sadler

Scott Sadler

CMO · Chief Math Officer · FCIA

Scott brings actuarial discipline and an objective analytical perspective to complex insurance, protection and estate-planning decisions. Since 1997, he has worked in a non-traditional actuarial role directly with affluent Canadian families and their accountants, lawyers, bankers and advisers.

Scott approaches life insurance as one of several possible planning tools—not as a predetermined answer. He helps the family and its professional team understand a strategy's potential benefits, risks, assumptions and long-term implications before implementation.

Within the Family Tree process, Scott adds an additional layer of technical due diligence so families can understand not only how a proposed solution works, but why it belongs within the broader plan.

The numbers should clarify a decision—not obscure it.

  • Actuarial analysis
  • Insurance due diligence
  • Long-term policy and risk modelling
  • Education for families and professional advisers
Dirk Leavesley

Dirk Leavesley

CPO · Chief Planning Officer · CFP®, PFP®, RRC®

Dirk helps translate a family's goals, responsibilities and resources into a practical, coordinated financial roadmap. His work is grounded in comprehensive financial planning, with particular depth in retirement cash-flow strategy, tax coordination and estate planning.

Within the Family Tree process, Dirk works at the point where discovery becomes design. He organizes the facts, models different scenarios, identifies trade-offs and integrates cash flow, retirement, tax, estate, protection and investment considerations into one understandable plan.

His role is to ensure that every recommendation connects back to what the family is trying to accomplish—today, through major transitions and across generations.

A good plan makes the next decision easier to understand.

  • Comprehensive financial planning
  • Retirement cash-flow strategy
  • Tax and estate coordination
  • Scenario modelling and trade-off analysis
