About
## Randall Lindemann
**Architect, AIA, LEED AP, NCARB**
As President and Founder of RML Architects, LLC Randy Lindemann leads with direct involvement on all aspects of the company’s projects and client relationships.
Randy began his design career as assistant director of design at KKE Architects after receiving his Bachelor of Architecture Degree from North Dakota State University.
Over his long career, Randy has enjoyed mentorship from several highly skilled and accomplished architects guiding him through design of nearly $1B worth of small and large scale projects including highly visible government and justice facilities, naming 41 of the 83 Minnesota counties and nearly every Native American Tribe in the upper Midwest as clients. After 35 years, including his career at KKE where he served on the Board of Directors and as Partner in Charge of the Public Sector Division, he left to pursue his life-long dream of building his own architectural firm.
In 2020, Randy founded RML Architects to help his clients realize their visions and to provide new opportunities to staff and clients by design.
Randy believes “how you do anything is how you do everything” and approaches every design and relationship with that challenge in mind.

## **Native Green Grow (NG2) Project – Parshall, ND**
!The NG2 Gas Capture Greenhouse project is a 40-acre, multi-phase project located in Parshall, ND on the Ft. Berthold Indian Reservation (FBIR) to achieve food sovereignty for the MHA Nation. The completed project will contain a 412,000 SF greenhouse (3 phases), an administrative building, a raw gas refinery plant and on-site sale marketplace.
By capturing gas from oil wells currently being burned (flared) off into the atmosphere and converting that waste gas into heat, CO2, and electricity to grow vegetable produce in self-contained, climate-controlled greenhouse, the innovative gas capture model extends the limited North Dakota growing season to a year-round operation, increasing production potential and reduces the harmful effects from flared gas.
“It’s one of the keys to ensuring that we survive, to ensuring our Nation will go into the future, growing our own crops, generating our own power, maximizing our water sources, and creating products to export so that when times do go rough, we’ve got a system in place that can really survive any difficulties that might lie ahead,” said Chairman Mark Fox.
