Who We Are

Redgarden Engineering



Redgarden Engineering was founded in October, 2008 to offer a high level of electronic design capability that clients may utilize exactly when needed. We can provide continuing support for our designs over periods of many years. Redgarden has an electronics lab to allow assembly, troubleshooting, and testing of prototypes.

We enjoy innovating, solving problems, and organizing complex pieces in useful, clear ways. We use the linguistics of science to differentiate hypotheses we suspect from theories that are solid. We have found the heart-based communications approach of Marshall Rosenberg compelling to engage issues with listening and communication.

We subscribe to the IEEE Code of Ethics. We see engineering as a means to create a more sustainable society. (Consequently, we choose not to work on projects involving weapons of mass destruction.)

Redgarden Engineering is named for the 700-foot high Redgarden Wall in Eldorado Canyon, the largest crag near Boulder, Colorado (and down the street from Redgarden Engineering). Redgarden's founder, Kurt Aronow, applies strategies to electronics engineering from climbing and chess. Both of these involve using classical routes & openings in addition to finding elegant, robust solutions for ambiguous, complex middle sections. For success, one must finish the route or play out the end-game precisely.

Speed to Market

Speed to Market
Meet Speed to Market Inc.

Tom Kroenke founded Speed To Market in 2001 to assist medical device companies to quickly obtain market access for their products, and to maintain that access through compliant products and systems. Medical device companies have more specialized quality assurance and regulatory affairs needs than other companies because medical device regulations are more stringent than those affecting most companies. Additionally, medical device companies are regulated by federal agencies in many different ways in almost every country. These quality assurance and regulatory affairs needs require specialized resources, especially when fast market access is critical to company success.

First and foremost, all Speed To Market products and services are focused on regulatory compliance. The risks to any medical device company are too great if it does not operate within the law. However, regulatory compliance is not mutually exclusive with fast market access. This is where Speed To Market products and services give your company an advantage.
