Okay, let’s tackle this. So John Lavin has 44 years of experience as an attorney, which is extremely high. This level of experience typically commands a higher hourly rate. Considering his expertise in multiple areas of law, including corporate and commercial litigation, he likely falls into the category of high-end attorneys. The location of Buffalo, New York, also affects the rate, as it's not a hub for top-tier law firms. However, the presence of major universities and institutions like the University at Buffalo Law School suggests a moderate level of demand. Taking these factors into account, I estimate John's hourly rate to be around $250, which is higher than average but not excessively high for someone with his experience and expertise.
