The attorneys at Clarion Law have significant experience at prominent Silicon Valley law firms and relevant in-house legal experience at technology companies.

Clarion Law attorneys are experienced transactional lawyers who understand how to bring contracts to closure quickly and efficiently. Because of this, we are able to deliver our services in significantly less time than other law firms. Moreover, we understand our clients' businesses, and we recognize that our role is to facilitate our clients' business objectives, not to create legal obstacles. We know when to raise issues in contracts and, more importantly, when not to do so. Companies use Clarion Law for its contract, transactional and corporate needs because our attorneys are more experienced in these types of matters than many attorneys at other firms. 

At Clarion Law, we aim to provide the highest quality legal services in our areas of expertise and develop long-term partnerships with our clients.
