Sonoma Lawyers

Sonoma is a historic city situated in the Sonoma Valley with the Mayacamas Mountains to the east, Sears Point to the southwest and the Sonoma Mountains to the west. As of 2010, Sonoma had over 10,500 residents. Sonoma is also well-known for its beautiful wine country and is also home to many historic and scenic locations including the Mission San Francisco Solano, the home of General Mariano Guadalupe Vallejo and the Presidio of Sonoma.

California State Route 12 passes through many of the most populated areas of the Sonoma Valley. It connects Santa Rosa to the north and Napa to the east. There are also State routes 121 and 116 that run to the south of town connecting cities such as Petaluma, Napa, Schellville and locations in Marin County. Highway 37 and the 101 are vital to travel to and from Sonoma as well. These roadways are where many of the most devastating Sonoma car accidents occur.

State Highway 121

Speeding is often a cause of serious injury accidents. Several people were injured in a Sonoma car accident on State Highway 121 when two vehicles collided with a big rig. According to a KTVU news report, the truck accident occurred just east of Eight Street just south of the city of Sonoma. All three vehicles were heavily damaged and a number of people suffered moderate injuries.

Highway 37

Another crash that involved a speeding motorist on a Sonoma highway resulted in the death of a family of four. On November 28, 2009, Steven Culbertson, 19, was traveling at 90 mph when he ran a red light at Lakeville Road and Highway 37. According to an ABC news report, his Mini Cooper clipped a Honda CR-V and broadsided a minivan carrying the Maloney family. John Maloney, his wife Susan and their two children, Aiden, 8 and Grace, 5, were all killed in the crash. Culbertson died later at the hospital as well.

Highway 12

Highway 12 is the site of many tragic accidents each year. On April 7, 2012, serious injuries resulted from a crash involving a red Mercury Cougar and a white pickup truck. According to The Napa Patch, the Sonoma County crashes occurred on westbound Highway 12 at old Sonoma Road. Officials say Stanley Hilton, 48, let his Mercury drift over the centerline where it struck a truck driven by Andrea Virdell, 39. A 40-year-old in the Mercury and a 23-year-old woman in the truck suffered significant injuries.

Dealing with Insurance Companies

A big part of handling a personal injury claim involves dealing with insurance companies. Whether it is an auto accident, a dog bite claim or an on-the-job injury, it is critical that victims exercise caution in terms of what they say or the actions they take. Personal injury victims with pending claims should remember not to sign any papers or rush into agreements without first talking to their own attorney. Once an agreement is signed, the case will be closed and it will not be possible to claim additional compensation that may be needed to pay for future medical costs and other expenses related to the injury.

Contacting a Sonoma Personal Injury Lawyer

The experienced Sonoma personal injury lawyers at our law practice have more than three decades of experience helping injured victims and their families seek compensation for their injuries and losses. Be it against a reckless driver, a negligent corporation or a nursing home that abuses or neglects its elderly patients, we have fought tirelessly for the rights of our clients and helped hold the at-fault party accountable. Our attorneys work on a contingency fee basis, which means that we do not get paid until you get compensated for your losses.

Client Reviews of Bisnar Chase

“I don’t even know where to start, because I really wanted to write this recommendation even if there was no star or rating to be given! My daughter and I were in a bad car accident in 2011. She received a broke jaw, broken pelvic, broken arm, and a ruptured ear drum. I prayed to the lord while I was in ICU to guide me and send me to the right attorney that would help me and my daughter and not just look at us as a monetary opportunity. After much research I choose Bisnar Chase.
After spending 2 months in the ICU, we were in a long recovery process. Learning to walk, to eat due to wire shut for months! Back to the basic all over again… 4 years later it just came to an end! I tell you I have 2 different paralegals assisting me but Colleen Cadogan was the best I had this past year… This lady, emailed me, called me, send me words of encouragement almost every week! When I least expect it and I had a horrible day or had many questions and concerns she was there! As the paralegal doing her job, but also as a human being, a mother, a wife….just genuinely concern for my daughter and I. As the case came to a close….I will always remember the team of professionals and I would recommended Bisnar Chase to anyone….and be patient, patience”

“We received an email from A.G. Edwards stating they have received the settlement check from Nissan. Once again, I cannot begin to articulate our gratitude to the Bisnar Chase staff - we are so very thankful for all you have done for Josh. As parents, Charlotte and I can rest in peace, when that day comes, knowing that Josh's needs have been taken care of, and his financial future is in good hands with sound financial planners at A.G. Edwards. On December 17, 2003 we received a call from the paramedics stating that Josh and Lisa had been in a severe accident, and we needed to meet them at the emergency room. I remember telling God that I can deal with missing limbs because they can be replaced, but please do not take him from us. A month later we met with members of your staff for the first time, Josh had a traumatic brain injury and his future was looking pretty bleak; we had no idea where he would be eighteen months later. All we could think of at the time was that our son's future, his goals, and dreams had been taken from him so abruptly. As time passed, Josh continued to improve and he began his journey of recovery. Many have been involved in this process, and you and your staff have been an integral part of Josh's recovery, and we will be forever grateful. God has brought so many people into our lives, and we are so very blessed. Numerous emails were sent to Personal Injury Attorney's. John...you were on a ski trip at Big Bear with your family, and you were the only Personal Injury Attorney to respond - I believe this was divine intervention. Josh has a professor from Mt. San Jacinto College who has taken him "under his wing," and is showing him other career possibilities. John, the future looks good for Josh - thank you!”

“I cannot speak highly enough of Bisnar and Chase. They represented us when we were hit by a government drunk driver on base while my husband was enlisted in April 2010 and stayed diligent throughout our long federal case. They handled everything start to finish and held our hands the whole way!”
