"I went to Geico across the street before going to Karen’s state farm. Karen helped me lower my home and auto insurance overall and explain to me details of the policy. She offered me better coverage while keeping the price low. She’s very knowledgeable with what state farm offers including their competitive rates. Very happy with my experience with Karen and team."

"I haven’t yet used Karen, but she was highly recommended by a valued member of my community. We spoke briefly and she is very professional and customer service oriented. I’m impressed that she picked up the phone and spoke to me directly. I’ve had some bad experiences with agents outside of State Farm in the recent past and I’m looking to make a change. Customer service and answering the phone, as well as knowledge would all point to Karen for me ! I see she is very busy and so am I so I appreciate that she is very results-oriented, does not waste time and is very pleasant to talk to, and it appears she sincerely wants to help in the most efficient way possible."

"Karen did an excellent job saving me and my wife a lot of money by switching to State Farm. She is diligent and efficient in finding you the best savings possible. She also found us some really helpful homeowner's coverages that I didn't even know existed! I can recommend Karen with the highest confidence."

"We asked Karen & Dan to review our home and Auto insurance that we had with MetLife to see if there could be some savings. We were thrilled to see that State Farm could provide higher coverage and saved us over $$$$ a year. Karen was professional, knowledgeable and answered all my questions and got me everything I needed. Looking forward for next appointment."

"Joined State Farm about a year ago when seeking out insurance on a Collector Car at best-rate; added Auto and Homeowners with Rider & Umbrella. HUGELY helpful in just my 1st year of coverage -- Karen & Team covered my cost-of-replacement for whole-home back-up generator after it was infested by rodents. Extremely professional, courteous, helpful, responsive, and tailor-made insurance provisions. AAA+++ Would definitely recommend for top-to-bottom coverage with personal touch."

"I just transitioned from having car insurance with Geico to State Farm, and I recommend this agent 100%! The switch was so smooth and customer service representative Alma Soto patiently answered all my questions accurately and honestly. She's great to work with and responded in a timely manner. Not to mention I saved A LOT, considering I have just started purchasing car insurance as a fairly new driver in May. Thank you Alma and Karen C. O'Brien's team for making all this possible!"
