About Nathan

A career that began in an unlikely place.

My work as an organizational psychologist began in Mongolia. I was teaching English during an extreme winter, what locals call a dzud, and watched ordinary people draw on resources I didn't yet have language for. Rather than try to forget what I'd seen, I dedicated my career to understanding and improving workplace systems, leadership development, and organizational effectiveness.

I hold a PhD in Industrial-Organizational Psychology from Seattle Pacific University. At California Baptist University, I designed and now direct the Master's in Industrial-Organizational Psychology, which OrganizationalPsychologyDegrees.com ranked #10 among campus-based programs in the United States in its 2025 list. In eight years the program has prepared 200+ alumni now working across Fortune 500 firms, global consulting groups, and mission-driven institutions. More than 60% were in a relevant role within three months of graduating, and about 70% within six months. About 8 in 10 are the first in their family to earn a graduate degree. In 2024, Latinos in Industrial-Organizational Psychology honored this work with their Advocacy & Inclusion Award. I speak Spanish fluently and offer coaching and training in English and Spanish.

“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, drawing on industrial-organizational psychology and cross-cultural leadership research. 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, where I led a trade delegation to Gangnam, South Korea, advised on a proposed $50M Korean cultural center, and coordinated diplomatic engagement with delegations from Germany, Vietnam, Mexico, and South Korea. My consulting practice spans the United States, Mexico, and India, and I've presented research at the Society for Industrial and Organizational Psychology, the European Association of Work and Organizational Psychology, the Chartered Institute of Personnel and Development in Dublin, and the Western Psychological Association.

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.

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.

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, Mexico, and India.
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, India, the UK, and South Korea.
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 are in the For Organizations section, and I am glad to send a capability statement and to invoice in the format your finance team prefers.
How much does coaching cost?
Investment varies by scope. A single-leader engagement is priced differently than a leadership team program or an organization-wide effort. After a free 30-minute discovery call, I'll share an exact proposal that fits your situation. Most professional development budgets cover individual coaching engagements, and I'm happy to provide an 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?
