Tasso’s Expertise


Life is full of uncertainties. Taxes don’t have to be one of them. Inadequate tax planning or improper handling of tax issues can result in major financial consequences and restrict your company’s growth.

Estate and Tax Planning to Protect your Legacy

Integrating your tax structuring is crucial for all ultra-high-net-worth families. This includes will planning, the use of trust, estate planning, and investment structure optimization — all of which maximizes tax efficiencies and minimizes the burden on you and the next generations.

Transition and Succession Planning

For business owners, the business itself is the ultimate investment. It’s often all in, and the way to retire happily ever after. But what if “ever after” comes before you’re happily prepared?

Creating And Managing Your Wealth

Since inception, we have been driven by independence and objectivity. We are not beholden to one investment solution or limited by the number of investment opportunities available to us.

Giving Back To The Community – Philanthropy

Charitable giving is often an expression of your core values; it represents you and your legacy to the community. It can also be a family project that brings the next generation into the fold in a meaningful way.

Keeping Your Family Safe

Life insurance can be an investment for families to provide liquidity at death or for philanthropic objectives. We help you evaluate if life insurance can meet objectives.

Navigating Family Dynamics – Governance

With great wealth comes great responsibilities towards the community, family members and generations to follow. Developing clear governance systems ensures family harmony and, ultimately, intergenerational success.

Preparing Your Next Generation – Financial Literacy Program

Richter’s Financial Literacy program is a customizable way to educate family members around key areas of family wealth and business management.
