A native of Grand Rapids, Michigan, DL enlisted in the United States Marine Corps immediately after high school. He served as an Aircraft Firefighter and Emergency Medical Technician, cross-training with structural fire departments at Camp Pendleton and deploying during Operation Desert Storm.
After his military service, DL graduated with honors from UCLA and attended UC College of the Law, San Francisco, formerly UC Hastings College of the Law. He served on the Trial Team, received the Moot Court Award for Best Oral Advocate, and worked with the Legal Education Opportunity Program mentoring first-year law students.
DL began his legal career on the defense side, representing healthcare professionals, medical institutions, businesses, and individuals. That experience gives him insight into how defendants and insurers evaluate exposure, and he now brings that perspective to plaintiff-side cases.
His background in emergency medicine, regulatory issues, and trial work helps him evaluate complex medical evidence and advocate for families harmed by negligence and institutional failures.

Caring for residents with dementia requires patience, training, and constant supervision. Many individuals living with Alzheimer’s disease or other forms of dementia experience confusion, memory loss, and disorientation that can place them at serious risk if they are not properly monitored.
One of the most dangerous consequences of inadequate supervision is wandering.

For many nursing home residents, catheters are medically necessary devices used to assist with bladder function and other health conditions. While catheters can improve comfort and medical management when properly maintained, they also require careful monitoring, hygiene, and professional handling.
When nursing homes fail to provide appropriate catheter care, residents can suffer painful infections and severe complications that may have been preventable.

Bed alarms are commonly used in nursing homes to help protect residents who are at risk of falling or wandering. These systems are designed to alert staff when a resident attempts to leave a bed without assistance, allowing caregivers to respond quickly before an accident occurs.
However, when bed alarms are improperly managed — or ignored altogether — the very systems meant to improve safety can become ineffective.

For many nursing home residents, moving from a bed to a wheelchair, standing up, or using the restroom is not something they can safely do alone. These movements — known as resident transfers — require proper assistance, training, and attention from caregivers.
When transfers are handled incorrectly, the results can be devastating.
