Posted by anonymous | December 10, 2025 | Consulted Attorney

This review is from a potential client who consulted with this attorney.

No credible investigation

My younger brother died at Wilmington Hospital in what their Director of Patient safety and other doctors there called an "unexpected death". My M.D. associates and others (PIs) believe that what occurred is likely more than (extensive) medical negligence. (I also have an M.D., from Cornell Medical C...ollege) Records were falsified and fabricated from the start of my brother's arrival at the hospital. The attending then provided what the ME called "disinformation" in an initial attempt to prevent investigation by his office. Nevertheless, Lengkeek took my case information, and then almost immediately dropped any review of the matter based on some issue he characterized as: "regardless of the relevance to your brother’s passing". That is not acceptable. He did not even for a single second discuss anything with me about any issue. He is no credible investigator. I would not trust this attorney with your case whatsoever.

I'm sorry that we were unable to investigate this matter on your behalf. We receive numerous inquiries every week regarding potential cases and we are unable to investigate each and every one. My condolences on the loss of your brother and I encourage you to reach out to other lawyers who practice in this area for another opinion.

A Patient's Partner

After having an auto accident driving home with my family after a business meeting, I had no idea how much time and medical intervention would be required. I found quickly I needed support from the medical bills and guidance of what to do after getting hurt. Mr. Lengkeek and his assistant Kerry were ...an outstanding team that treated me with respect and stood by me, helping and guiding me the entire duration. Tim and Kerry gained my respect very quickly. They were fast and proactive always working on getting the bills paid and assisting me when I needed direction. Tim's unique knowledge base provided me with information that was required from understanding surgeries to dealing with insurance companies and the like. Kerry provided me with weekly if not daily interactions to keep me in the loop. This made not only me feel comfortable but also my family. They were/are truly my partner helping me step by step. The settlement outcome was much more then anticipated and was simply due to the dedication and hard working team of Mr. Lengkeek. I am completely satisfied with the outcome and I would highly recommend Tim to anyone who wants full commitment and to get the job done with a personal touch. A truly pleasant experience considering the medical inventions I had to undertake. I was not just a customer, I was a VIP.

Best of The Best

Mr. Lengkeek blew the defense out of the water. He was well prepared and had a answer to what ever they came up with. I recommend him 100 out of 100. I am glad I used him for my case. we won more that I expected.

Excellent Attorney!!!

I hired Mr. Lengkeek to represent me in my Personal Injury and Workman's Comp cases. Mr. Lengkeek, together with the expert witnesses he hired on by behalf, was able to convince the jury to award me a great settlement!! Professional and informative from start to finish!!

Second Case using Tim Lengkeek

Met Tim late in 2009 after a January car accident which he handles after my PIP ran out. Due to personally knowing my boss we had not filed a W/C claim and since she had us run errors after work we did not know the law. Buy Tim did and he worked with his office and my husband to come up with a plan t...o get the employer to tell the truth that I was covered . We won the claim but she fought it again and lost a 2nd time. They have dragged me to the labor board to make me go back to work and never told the person they hired that I had a brain injury just a slight speech problem and that I could not sit for very long. My medical records stated I had injured my left shoulder and needed surgery and one of the jobs he had for me was toll taker using left hand. Brain injury can't count money, type understand people at a normal speed of speech, but the employers lawyer had the employer give him my resume I had given her when she hired me and oh boy did she talk up my abilities. Not one job was I capable of doing and Tim dug in and broke it all down to the fact that the employer did not want to keep paying the claim. We trust Tim because he listens , knows the law and is very calm unless someone is out of line. Don't hesitate to hire him. If you are completely truthful he will back you up all the way!
