Who We Are

Arrien Investments is an independent Registered Investment Adviser based in Boise, Idaho. As a fiduciary, we're required to put your interests first. Established by Kevin Arrien in 1997, Arrien Investments is a full-service fee-only financial advisory firm. Our firm offers retirement planning, tax optimization, estate planning, investment management, budgeting, and business planning to help clients and companies meet their financial goals.

We realize that each situation is different and do not use a "one size fits all" approach when assisting clients. Instead, each financial strategy is tailored to the needs and goals of each individual person or organization. We pride ourselves on our strong customer service and enjoy assisting clients in the maintenance and improvement of their personal financial situation.

Why Arrien Investments:

Independent and fiduciary. We're a Registered Investment Adviser. No parent company, no house-brand products.

Boise roots. Founded here in 1997. We live where you live, and we answer our own phones.

Clear fees. Pick ongoing investment management or hourly financial planning. 

Who we work with:

Tech and Business professionals with equity compensation. If RSUs, stock options, or an ESPP make up part of your pay, you've got a tax and planning puzzle. We help you figure out when to exercise, when to sell, and how to turn equity into a plan.

Physicians and attorneys. Big incomes, late starts, heavy student loans, complicated benefits. We help you catch up and protect what you're building.

We also work with individuals, families, and business owners across the Treasure Valley who want honest planning and straight answers.

How we work:

Intro call or meeting. Free, 30 minutes, no pitch. We both figure out if it's a fit.

The plan. We look at everything together: retirement, investments, taxes, estate, insurance.

Ongoing. We manage, watch, and adjust as life changes. You always know where things stand.
