asks why, then asks why not.
Building science, sustainability, and indoor environmental quality, from a mechanical engineer who grew up around people who studied ecosystems for a living.

About
Principal and VP at BranchPattern. Recovering perfectionist.
I'm a mechanical engineer who ended up obsessed with air. Not the metaphorical kind: the kind you're breathing right now, indoor air, outdoor air, and the overall quality.
My father ran the Jay C. Hormel Nature Center in Austin, Minnesota, where I was born. We moved to Omaha in 1988 when he took a job with the Nature Conservancy. Growing up around people who studied outdoor ecosystems for a living gave me an early interest in the environment. It became an interest in the indoor environment once I trained as an engineer: same physics, same stakes, much smaller scale. Meanwhile, my mom showed me how to lead, manage, and achieve in all areas of life (inspiration I carry forward into my coparenting and work).
I work across integrative design, building performance modeling, sustainability consulting, indoor environmental testing, and commissioning in new and existing buildings. Corporate real estate, K‑12, higher ed, multifamily, entertainment, institutional, recreational. If a building has an HVAC system and people inside it, I've probably worked on something like it, for clients ranging from local nonprofits to Fortune 500 companies.
In 2021, I was named a LEED Fellow, one of 21 people worldwide that year. I still ask "why" and then "why not" more than is probably comfortable for the people around me.

Also building
The parts of my life that don't fit on a résumé, but still take up real estate in my head.
AI x CRE ↗
A practitioner-led working group I started for commercial real estate professionals learning how AI actually changes the work. Over 100 members, monthly sessions, now forming into a nonprofit resource for women in the industry.
Sustainability Vetting Guide ↗
A free guide for owners and architects evaluating engineering teams on sustainability practice, covering nine categories from carbon disclosure to indoor air quality.
Oscar Watch
A yearly goal to see every Best Picture nominee before the ceremony airs. Equal parts film education and logistics puzzle, depending on how late the nominations land.
Cutting Open Rocks
Working with my son to create a dedicated socials channel dedicated entirely to cutting rocks open to see what's inside.

Speaking
I routinely speak and present on building science, sustainability, and indoor environmental quality. These are just some of the topics I'm talking about currently — happy to develop a custom presentation or topic as needed, including for CEU requirements.
Crafting Excellence
The collaborative art of project delivery: early alignment, the integrative design process, and why sustainable outcomes are a moral question as much as a technical one.
The ROI of IEQ
Indoor environmental quality through the lens of LEED, WELL, and Fitwel: what these frameworks measure and the return they generate for owners.
IAQ Sensors, Show and Tell
A hands-on look at indoor air quality monitoring hardware, what it's good at, where it falls short, and where the category is headed.
The Benefits of Commissioning
Commissioning types (including monitoring-based, enclosures, and systems), the deficiencies it's built to surface before occupancy, and where it connects to other services.
WELL and Fitwel Standards
A working guide to both wellness frameworks: air, water, light, and movement, and how to apply them across building types.
The LEED Rating System
A deep dive into LEED, scaled to the audience: an introduction for the newly certifying, an advanced session for the already fluent.
My AI Life: Avoiding Reverse Centaurs
On using AI to amplify judgment instead of replace it: what responsible delegation looks like, and why the human stays accountable for the decision.
Decarbonizing the Buildings We Already Have
Existing-building strategy under LEED v5 O+M: where the carbon actually is, what's cost-effective now, and how to sequence the rest.
The Work You Do Today Sets You Up for Tomorrow
On mentorship, networking, and saying yes to the small things: practical talk for people earlier in their careers about building a path, not just a résumé.
Video examples and IAQ monitor reviews on YouTube. Get in touch to scope a session on any of the above, or something not on this list.
Media
A working archive, including interviews, articles, and the occasional podcast tangent.

Speaking requests, project inquiries, or something else entirely. Historically, "something else" has included restaurant recommendations or discussions about new interesting music or concerts, which are also welcome.
