Client Spotlight

What our clients say.

“I’ve never had an insurance agent be so helpful, and so caring before! I’ve been with Allstate, Farmers, Progressive, and now with Safeco. Hands down the best in Clark county! Cherie Walker was so helpful trying to help me figure out information about my old policy and I wasn’t even a client at the time!”


“I’ve always received excellent service and the entire staff at Nicholson & Associates is very professional and pleasant to work with.”


“Great place for low rates and excellent staff and service I recommend all I know looking for insurance.”
