Capability statement Download PDF
Tribal Nations, the Northern Plains, and Canada

Partnering with the communities close to home.

I grew up on a family farm in Brookings County, South Dakota, and my family also has roots in Alberta. I am a dual United States and Canadian citizen. I want Momentum to be a good partner to tribal nations and communities in and around South Dakota, and to organizations in Alberta and across Canada.

Every community knows its own leadership traditions, strengths, and priorities. I listen first, bring research and practical tools where they are wanted, and build programs together. Leadership development, training, and organizational assessment can each be shaped around what a community asks for.

If you lead a tribal enterprise, a tribal college, a health or workforce program, or a Canadian organization and would like to talk, I would be glad to hear from you.

About Nathan

A career that began in an unlikely place.

My work as an organizational psychologist began in Mongolia, where I taught English through an extreme winter, what locals call a dzud, and watched ordinary people draw on resources I didn't yet have language for. I have spent my career since understanding and improving workplace systems, leadership, and organizational effectiveness.

I hold a PhD in Industrial-Organizational Psychology from Seattle Pacific University and direct the Master's in Industrial-Organizational Psychology at California Baptist University, ranked #10 among campus-based programs in the United States by OrganizationalPsychologyDegrees.com (2025). In 2024, Latinos in Industrial-Organizational Psychology honored this work with their Advocacy & Inclusion Award.

“We have a daily opportunity to choose between victim and agent.”

Through Momentum Coaching + Consulting, I advise leaders on leadership formation, strategic alignment, and organizational culture, grounded in evidence-based practice. I've designed executive programs for global brands, supported leadership integration through mergers and acquisitions, and led executive retreats for nonprofits and private organizations. From 2022 to 2023, I served as International Relations and Protocol Officer for the Office of the Mayor, City of Riverside, and I later chaired the city's Parks and Recreation Commission. I speak Spanish fluently and offer coaching and training in English and Spanish.

A dual US/Canadian citizen, I grew up on a family farm two miles outside a South Dakota town of 200. Leadership across very different worlds has been lived experience as much as research interest.

Frequently Asked

Questions people ask first.

If you're wondering whether Momentum is right for you, start here, or skip to the 30-minute conversation.

What is Industrial-Organizational Psychology, and how does it shape coaching?
Industrial-Organizational Psychology is the scientific study of human behavior at work. It applies peer-reviewed research on leadership, motivation, team dynamics, and organizational culture. My coaching integrates that research with real executive practice, so you get both evidence and experience.
Who is Momentum's coaching for?
Individual executives navigating growth, transitions, succession, or the weight of the role, and organizations investing in leadership development, executive retreats, mergers and acquisitions integration, or culture work. Most clients come from Southern California, though I consult across the US, Canada, and Mexico.
Where are you based, and do you travel for engagements?
Momentum is based in Riverside, California. I meet one-on-one clients virtually or in Southern California, and travel internationally for corporate engagements, retreats, and keynotes. Past work spans the United States, Mexico, South Korea, the UK, Ireland, and Poland.
What happens in a free 30-minute information session?
It's a short, no-commitment conversation. I ask about your situation and what you're hoping for, whether that's coaching for yourself, a program for your team, or something in between, and share an honest view of whether Momentum is the right fit. No pitch, no pressure. Book via Calendly.
What are Nathan Iverson's credentials?
Nathan holds a PhD in Industrial-Organizational Psychology from Seattle Pacific University. He is Program Director of the Master's in Industrial-Organizational Psychology at California Baptist University, ranked #10 among campus-based programs in the United States by OrganizationalPsychologyDegrees.com (2025). He writes regularly for Psychology Today's "The Evolving Workforce" column and has been featured in Authority Magazine, ABC7 Los Angeles, University Business, and Voyage LA. His peer-reviewed work appears in Organizational Dynamics and International Perspectives in Psychology.
Do you offer therapy or mental health services?
Momentum provides coaching and consulting. When clients need mental health support, we refer to Dr. Bergin Family Counseling Services, a trusted practice with licensed therapists offering compassionate care.
Do you offer coaching and training in Spanish?
Yes. I speak Spanish fluently, and coaching, workshops, and facilitation are available in English, in Spanish, or in both.
Can public agencies, health systems, and tribal organizations contract with Momentum?
Yes. Momentum is a California limited liability company with a SAM.gov Unique Entity ID and a California eProcure Bidder ID. Our business identifiers and a downloadable capability statement are in the For Organizations section, and I am glad to invoice in the format your finance team prefers.
How much does coaching cost?
A six-month executive coaching engagement starts at $3,500. Workshops and training start at $5,000 per day plus travel, and organizational and culture assessments start at $7,500. After a free 30-minute call, I'll send a fixed proposal that fits your situation. Most professional development budgets cover individual coaching, and I'm happy to invoice in any format your finance team prefers.
How long is a typical engagement?
Most individual coaching engagements run about six months, with biweekly 60-minute sessions and light support between calls, followed by optional monthly check-ins for clients who want a sustained thinking partner. Shorter engagements (single sessions, intensive workshops, retreats) are also possible, but most of the value comes from sustained work over time.
What if it's not a good fit?
The free 30-minute discovery call exists for exactly this reason. If the work isn't right for where you are or what you need, I'll say so, and often refer you to a colleague who's a better fit. There is no obligation to move forward, no follow-up sales pressure, and no awkwardness if you decide it's not the moment.
What moves you?

Let's start a conversation.

Ready to create momentum? The first step is a conversation about where you want to go and how we can get there together.
