Exceeded Expectations
Mark carefully assessed my case in the beginning and patiently pursued a settlement that was much higher than I ever imagined we could reach. As an attorney myself, I greatly appreciated Mark's communication, professionalism and depth of experience in negotiating with insurance companies. I would highly recommend Mark to anyone who has been injured in a car accident and is not sure how to proceed in order to receive a full and just recovery.

Excellent Customer Service and Responsiveness
After several weeks of challenging interactions with the insurance company of the party who struck my vehicle, I contacted Mark’s team. They supported me throughout the legal process and handled the difficult negotiation with the other party's insurance company. His team’s responsiveness and persistence were a great comfort and I have recommended their services to colleagues and friends in Colorado. Mark’s team was enthusiastically recommended to me by a close friend in the legal field in the Denver region.

Mark was great in all aspects of his service to me and my family members. I have sent numerous people to him and they all share the same opinion. All attorneys should use Mark as an example of excellence in the Law.

Couldn't Be Better!.
I Hired Mark at the time of the Consultation. He was honest informative, forthwright , interested ,knowledgeable,considerate and compassionate. His attention to detail and ability to follow through was amazing, Mark demonstrated great integrity,dedication, and desire to adhere to a specific timeline throughout the process. He was steadfast about accumulating the necessary data and submitting it to the insurance Co. He was in constant communication with me as was his staff. I was never left in the dark about anything;they were always there for me should I have a question. Our case was not very easy since the opposing party took the position that we had no case. I was awed by Mark's immediate response quoting from his head two separate cases and Colorado Statutes derived from these cases to show that their position was inaccurate, Within minutes he had the cases in front of him ; told them to reference these cases. I was Amazed and Impressed! At that point they went home to regroup. Mark and his team had done their homework. We did better in the end than anticipated. The entire process was completed with the least amount of stress, was financially satisfactory, and Mark went beyond expectation to insure that I was satisfied with his total work accomplished, This was a Five Star Performance in Every Respect. I am overly satisfied in every respect and continue to recommend Mark to others.

Great Attorney!
Mr. Mark Biddison has represented me in court several times and always did an outstanding job! He has a brilliant mind which is evident in working a case, especially when presenting in court. In one situation with multiple defendants, Mr. Biddison led the way with all the other attorneys following his exceptional leadership and professional advise. His is and will always be my first choice when I need legal help in any situation!

Very Impressed.
In October of 2015, I retained the services of Mark Biddison to represent me as a victim in a motorcycle-vehicle collision. Because this accident was work related and involved four separate insured interests, I expected resolution of this claim to be expensive, messy, and time consuming. In the course of only fourteen months, Mark negotiated fair and equitable settlements with all parties against whom I had claims. While not being privy to the actual discussions directly, I can attest to the seriousness with which insurers regarded Mark’s presentation of my case. It was very clear that opposing parties knew that my claim was presented by Mark without ‘puffing’, exaggerated antics, or overreaching demands. Mark spoke — they listened. Mark Biddison is a credit to his profession. I cannot recommend the services of Mark and his staff highly enough.

Although I feel I got screwed and am having a very hard time getting used to my new life being crimpled. I like my attorney. None of this is his fault. I meet him a few days after the accident in the hospital. From then on he has always been available for me. He definitely kept me up to date, and was very straight forward even with the bad news.
