Owner-aligned project execution built on disciplined MEP coordination, rigorous QA/QC, and commissioning that proves it works.
We stand up, staff, and lead the delivery teams that turn megawatts into commissioned, operating capacity.
A delivery firm for hyperscale and mission-critical data center programs — principal-led, technically fluent end to end, built to hold a seat or run an entire delivery scope under the prime.
Principal
A career built from the conduit up — IBEW journeyman electrician to principal. 17+ years building mission-critical and hyperscale environments, with deep ownership of MEP, QA/QC, and L1–L5 commissioning, currently leading delivery on a 168 MW hyperscale build.
I've run the wire and I've run the program. That field foundation is the edge: I read a problem on the floor before it reaches the schedule, I know when a commissioning script proves something and when it's theater, and I can't be snowed by a sub. The same instinct shapes how I build teams — recruiting operators who hold the line and structuring ownership so quality and schedule survive every shift, trade, and handoff.
The result for a program: technical intent that doesn't get lost between design and turnover, and a delivery organization that scales without lowering its standards.

Behind-the-Meter Power
Fuel cell and gas generation, utility coordination, energization.
Utility & High-Voltage Power
Utility-scale power delivery and substation/HV coordination.
Procurement & OFCI
Long-lead and owner-furnished gear: UPS, switchgear, NETA testing.
Brownfield Redevelopment

Schedule & AHJ
Look-ahead and milestone control; permitting, jurisdiction, inspector relationships.
High-Performing Teams
Talent is the delivery system.
On a hyperscale program, the schedule is only as good as the people executing it. Reliant's core service is building delivery organizations that perform under pressure — recruiting the right operators, structuring clear ownership, and leading them to milestone. We don't just fill seats; we build benches that scale with the build.
01 /
Recruit
The right operators, fast.
A deep field and management network across the mission-critical trades — superintendents, MEP leads, commissioning managers, and project engineers vetted for hyperscale.
02 /
Structure
Clear ownership, no gaps.
Defined roles, reporting lines, and accountability so quality and schedule hold as the team grows from a seat to a full delivery organization.
03 /
Lead
Standards that survive scale.
Hands-on leadership that keeps technical intent and QA/QC discipline intact across every shift, trade, and handoff — then develops successors to run it.

Program Experience
Programs across Phoenix AZ, Big Spring TX, Santa Clara CA, Hillsboro OR, Des Moines IA, Windsor CO, and Vancouver BC — 7 states and 2 countries. Scope spans brownfield retrofits and campus additions through full ground-up buildouts, delivering over 1 GW of compute capacity to hyperscale and colocation clients.
Prior senior roles at DPR, Sundt, and GCON, scaling an Advanced Technology Division from roughly 5 to 150+ projects. IBEW Local 640 journeyman electrician by trade.
Engagement Model
Reliant engages as a principal-led delivery partner — we can hold or sub under the prime, staff the seats a program needs, and lead them to milestone. Incentives align to delivered, commissioned capacity, so the structure scales with the build rather than sitting as fixed overhead.
