He is one of the most responsive, trustworthy, competent professionals I’ve ever met, always going beyond the call of duty – often at his own expense – and always making his clients’ best interests his top priority.” – Chuck Oehler, Chairman and CEO, Primorigen Biosciences, Inc.

“...your entire staff spoke very highly of you personally. What a great testament to you, both as a great attorney and also as a great person.

  • Coordinated the incorporation of a biotechnology company, a joint venture arrangement between our client, an Indian biotechnology company, and a San Diego biotechnology company to research our client’s patents. This was a joint collaboration involving the transfer of patents, the sale of a business and the transfer of stock (all capably handled by our law firm).
