About me

Thank you for visiting my Web page.


I was raised in a small Illinois farming community. I trained and practiced in the Chicago area for many years before moving to California. At some point in high school, I knew I wanted to be a physician and care for others. I love the practice of medicine because I get to blend some of the best technology our society has to offer with the ancient art of healing and communication. I have been a patient and anxious family member myself, and know how hard it can be.

About my practice

I’m a hospitalist and critical care physician. This means I only practice in the hospital. In most instances, I’ll be the captain of the team of doctors caring for you. I will help you navigate the maze of hospital medicine, which has its own logic and is very different from outpatient or ambulatory medicine. Due to the nature of my practice, my members are already ill when we first meet. This is a stressful time for you. One of my partners or I will be available 24 hours per day to make sure you’re seen by the right group of physicians. I will make every effort to keep the stress to a minimum. I will answer your questions, and get you the help you need to recover and return home. My practice is split into two halves. As a critical care physician, I work with a team of subspecialists, each blending their skills to help our members in the Intensive Care Unit ICU) or Critical Care Unit (CCU). I’ve spent over 30 years taking care of ICU patients. In the other half of my practice, I work as a hospitalist—a specialized physician who is the "primary care doctor" for hospitalized members. Hospitalists work to resolve your condition, relieve suffering, and help you and your family with the transition. Upon your discharge, you will have you written instructions concerning everything you need to know. We ensure your primary care physicians and specialist also have this information so they’ll know about your tests, treatments and reactions during your hospitalization.

How I thrive

My life outside of work is filled with family. My wife and I have raised four children. I have coached baseball, softball, and football. When I'm not driving to dance classes or listening my son's latest aria, I’m gardening or simply relaxing with my family. I go to the gym four days per week, and we walk as a family at least three days per week. My favorite snack is a cut-up apple I can enjoy over 10 minutes or more.
