Competent on energy law, but communication was inconsistent

Dennis Langen is clearly a knowledgeable attorney, as his recognition in energy law suggests. I retained him for a complex matter involving regulatory compliance for a small renewable energy project in Northern California. His analysis of the administrative law hurdles was thorough, and he leveraged his decade of experience effectively. However, the experience was mixed. While the legal work was solid, there were significant delays in receiving responses to emails, sometimes stretching over a week, which created anxiety during time-sensitive phases. His billing was precise, but the overall process felt less collaborative than I had hoped. For straightforward, deep-dive legal analysis, he is capable, but you may need to manage expectations around client communication and proactive updates.
