Pacer K. Udall

An avid outdoorsman who literally has a “Possible” pouch where he keeps EDC items and interesting nature finds that might be useful, Pacer is driven by faith in the future and known for his positivity and innovation in creating unique advantages for clients through their intellectual property.
(480) 830-2700


Perhaps as a byproduct of his fifth-generation eastern Arizona roots, hard work, and deep belief in the synergistic relationship between man and earth, Pacer recognizes that you reap what you sow and seeks to propagate impactful strategies and processes that build company value.

Pacer is not your typical attorney; his daughter declared that “playing in the dirt is [his] golf.” He doesn’t just like to get his hands dirty in his orchard and garden but is also hands-on as a team member looking out for clients’ intellectual property. His goal is a more-than-satisfied client that recognizes that their advantage is the team he assembled around them with everyone rowing in the same direction, dominating their industry, market, and competition.
