About me

Hello, and welcome to my Web page! Hopefully, this page will help you get to know me a little better. My name is Alexander Bressler, but since childhood I have always been called “AJ” by my family and friends. I am happily married, and my wife and I have 3 awesome children. At work, I practice family medicine and sports medicine, in both the clinic and the hospital. At home, I practice soccer with my kids!


I was born in California but, being a military brat, I grew up all over the place. In the US, I lived in New Jersey, California (both Northern and Southern California), and Washington state. Overseas, I lived in England and Okinawa. While it was hard at times, I am glad I was able to experience so much diversity in both the people I met and the environments in which I lived. For the last 2 decades, I have resided in Southern California. I completed my bachelor’s degree at UC San Diego and then worked in the pharmaceutical industry as a chemist for almost 5 years. I attended medical school at Western University of Health Sciences in Pomona, and I completed my residency and fellowship training in family and sports medicine at Kaiser Permanente in Fontana.

About my practice

I am an osteopathic physician with training in family medicine and specialization in sports medicine. The whole person (mind, body, and spirit) must be considered to promote optimal health. Diet and exercise (or lack thereof) are the most important factors that need to be addressed to promote a healthy, balanced life, along with restful sleep and positive interpersonal relationships. As a family physician, I am happy to say that I can care for members of any age, from conception to hospice. It is now rare that I do any deliveries, but I am always happy to see newborns in clinic. I perform many procedures, such as biopsies, excisions, and joint injections (with and without the use of ultrasound). You will see me working in the medical office most of the time, but I do also treat members who are sick enough to be admitted to the hospital. I love teaching medical students and residents, so don’t be alarmed if you see them hanging out with me. On Friday nights during football season, you will probably see me volunteering as the team physician on the sideline of one of our local high schools.

How I thrive

I stay healthy by trying to eat well and exercise regularly. I lift weights and do high intensity interval training (HIIT) almost daily. I love to go hiking, backpacking, camping, and swimming. I also love to cook (and eat!). I spend as much time as I can with my wife and children, and weekends are usually packed with sporting events and other adventures.
