Jon Kleen

MD PhD

Neurologist and epilepsy specialist
Brain fanatic, computer programmer, devoted coffee drinker

Dr. Jon Kleen is a neurologist who specializes in epilepsy care. He is dedicated to improving the lives of patients with epilepsy by stopping seizures and finding new ways to overcome epilepsy-related cognitive issues, such as memory problems.

Kleen is a neuroscientist with expertise in signal processing (the use of computers to study patterns in large amounts of data), which he applies to cutting-edge diagnostic approaches and emerging therapies for epilepsy, including brain stimulation. As part of his research, he investigates how memory circuits work in the human brain and why they are disrupted in many people with epilepsy. He also develops technology that integrates brainwave recordings with brain images to help pinpoint where seizures start, with the goal of increasing the chance for future curative surgery in patients whose prior treatments failed.

Kleen earned a doctorate in neuroscience from Dartmouth College and his medical degree from the Dartmouth Geisel School of Medicine. At UCSF, he completed a residency in neurology, serving as chief resident, and a fellowship in epilepsy. He also completed postdoctoral training in human neurophysiology at UCSF. In 2017, he was elected by UCSF medical students for membership in UCSF's chapter of Alpha Omega Alpha for excellence in teaching.

Kleen enjoys spending his free time with family, as well as practicing Spanish and basic Mandarin, bicycling in Golden Gate Park, watching the ocean from San Francisco's landmark Sutro Baths, and getting lost in Wikipedia.

    I have never had a provider show so much interest in my health or listened to me as much as Dr Kleen does.

    Dr. Kleen always allows me plenty of room to speak and voice my opinions. Our conversations are never one sided he listens to what I have to say and takes my thoughts and ideas seriously. Dr. Kleen always provides a safe comfortable place to discuss and I feel a bit more relieved after each visit.

    I feel fortunate to work with Dr. Kleen. At baseline he is obviously a smart and very capable doctor. Why I switched care to him full time a few years ago from CPMC is that he is a kind and warm person. He remembers our conversations and the big things that have been happening in my life. He seems to really care about me as a whole person.

    Dr. Kleen is the best neurologist that I have had. He is kind friendly and has a great attitude each time I see him. He genuinely wants to address concerns of each patient and wants to find a solution.

    The BEST Doctor in all my life he really takes care of his patient. I visited too many doctors like 6 and nothing changed. The only that really took care about my condition was him my doctor Jonathan. I haven't have more seizures. I do not have words to say how blessed I am because I found him.

    Dr. Kleen is very professional and he has explained my medical issues in a way that I now better understand him. He has also motivated me to do well in college.

    I have seen more than three neurologist in the past three years and Dr. Jon Kleen has been the only one to really give me a different and very clear analysis about my condition and to be open to try other medicine that I hope helps in my condition he was very professional.
