Board Certification: American Board of Internal Medicine, American Board of Pediatrics

I was born and raised in the Philippines, but didn't get my inspiration to pursue a career in medicine until college, when I started volunteering for a nonprofit that cares for children with cancer. Now, I go to work every day with love in my heart - for my patients, for my colleagues and for my work. Yakima is a playground paradise for someone who loves the outdoors like me. I am an avid photographer and writer and I like to travel to discover new places. My father once told me that I should learn to slow down and "let the evening last," but I am always on the move, learning new things.

Medical school: Universidad de Costa Rica Facultad de Medicina, Costa Rica.

Residency: Internal Medicine, John H. Stroger Jr. Hospital of Cook County, Chicago, Ill.

What inspired you to choose medicine?  As soon as I started to study science I saw the human body as a miracle; it’s fascinating. Also, my father is a doctor and I look up to him so much. I feel like I’m doing something to make a change in people’s life.

Why did you choose your specialty? I like to see patients as whole people and not treat a part of them. Being a hospitalist, I get to see the patient as a holistic being.

What is your philosophy of care? I try to treat people like I would treat the people I love. 

What do you like about Yakima? Its people. People are smiling, they’re educated. People are actually concerned about each other.

What do you like to do outside of work? I like to read, do martial arts, play guitar, spend time with my wife and travel around and try different food.

Associate Medical Director

Christopher Catton

Medical School: University of Washington 1989

Residency: Internal Medicine Spokane 1992

Board Certification: American Board of Internal Medicine

Growing up as the son of an Air Force jet pilot allowed me to live in 12 different cities in my first 11 years of life. When my dad retired in 1974 we moved to Spokane, Washington, and I established roots in the Pacific Northwest. I met my wife Geri while in medical school and after residency we moved to Yakima where we are raising our five children and one golden retriever. I enjoy coaching my sons' baseball and basketball teams as well as attending my daughters' dance recitals. For our first 11 years in Yakima I enjoyed a "traditional" internal medicine practice. Five years ago, I transitioned to hospital medicine as one of the founding physicians of our growing hospitalist team. The small town feel and family friendly culture coupled with its close proximity to Seattle makes Yakima a great place to live, raise a family and practice medicine.

Residency: Internal Medicine, Monmouth Medical Center, Long Branch, N.J.

What inspired you to choose medicine?  I was supposed to be a molecular biologist, but my mom influenced me to go into medicine and I grew to really love it when I started taking care of patients.

Why did you choose your specialty? You get to take care of everything. You get to integrate everything and you don’t just focus on one aspect of the whole person.

What is your philosophy of care? You need to empower the patient to take care of themselves. I am there to guide them, but the majority of the responsibility falls to them.

What do you like about Yakima? The weather is really nice.

What do you like to do outside of work? I like to travel. I like to bike. And I want to try different things like fishing, snowboarding.

Residency: University of Texas Medical Branch at Galveston 2007

Board Certification: American Board of Internal Medicine

I was born and raised as a Filipino-Chinese, and eventually left the Philippines Islands after completing my B.S. in Medical Technology and MD as a Dean's Scholar at the University of Santo Tomas in Manila, graduating Cum Laude & Magna Cum Laude respectively. I moved to the United States in 2003 and settled in the less humid and hurricane-prone sunny island of Galveston, one hour south of Houston, Texas, where I completed my internship and residency at UTMB. I was honored as the "Most Likely Smiling Intern & Resident Award" two years in a row. My passion for hospital medicine led me to move to the fseasoned weather of the beautiful Pacific Northwest in the apple basin agricultural community of Yakima where I have been a hospitalist at YVMH since 2007. I have been very active in the medical community and hospital committees, including the Pharmacy & Therapeutics Committee, Anticoagulation Committee and Lab Q+ Committee, and serve on the YVMH Medical Executive Committee. I was appointed to the position of Chairman of the Department of Internal Medicine at YVMH in 2009 and also appointed to the faculty of Pacific Northwest University of Health Sciences as an Assistant Professor in the Department of Clinical Medicine. In 2011, I was elected Fellow of the American College of Physicians. In my spare time, I like to travel and attend continuing medical education workshops.

Dr. Adrian Crisostomo

Medical School: Far Eastern University, Philippines

Residency: Harlem Hospital

Board Certification: American Board of Internal Medicine

I grew up in the Philippines in a family of physicians: I am the 13th physician in my family, but the first to practice medicine in the United States. I worked as a primary care physician and as an ER hospitalist in the Philippines but ultimately decided I wanted to pursue my own path in medicine, travelling to the United States for a residency program at Harlem Hospital in New York City. I tend to be quiet and serious and often surprise people with my sense of humor. In my spare time, I like to exercise - I used to play basketball, but now enjoy running to manage my weight and stay fit.

In 2007, I moved to Michigan for my residency in Internal Medicine. During my residency, I married my wife, Pingle, who is a software engineer.

I grew up in a small town in the southern part of India and eventually moved to a bigger city to pursue a career in medicine. I have always enjoyed travel, outdoor activities and team sports, a personal favorite being cricket. I moved to the United States for an internal medicine residency in New York City, and I immediately fell in love with Yakima — the weather, the abundant nature and especially the people — when I came here for an interview. I feel blessed to practice medicine and serve this wonderful community. My wife and I are looking forward to a wonderful life here.

Medical School: Saint George's University School of Medicine, Grenada, West Indies

Residency Program: New York Medical College/Saint Michael's Medical Center, Newark, N.J.: Internal Medicine, Seton Hall University College of Health and Medical Sciences, 2013-2015

Dr. Lanham is from Cupertino, California and was inspired to choose medicine based on an experience with her pediatrician, Dr. Mac, and thought he was the coolest person in the world. She pursued internal medicine because you get a whole view of the person you're working with and can help them change the direction of their health. Her philosophy of care centers on education and providing information on how to best help each patient and giving them the tools to change their health. In her free time, she spends time with her husband and their dog, a Chihuahua-boxer mix, loves being outdoors and playing soccer.

Residency Program: Jersey Shore Medical Center 2010

Board Certification: American Board of Internal Medicine

I was born and raised in Trencin, Slovak Republic, a town similar in size to Yakima, and moved to the capital city of Bratislava after finishing high school. I studied at Comenius University Medical School, receiving my medical degree in 2003. I practiced internal medicine for two years there before moving to New Jersey in 2007 to finish residency at Jersey Shore University Medical Center. I joined Yakima Valley Memorial Hospital in 2010 and have found patients here very pleasant. I believe patients do better when they understand their health issues and can participate in their care, and I really appreciate the great team of hospitalists and specialists on staff here. On the personal side, I've found that Yakima has some beautiful places; the weather is fantastic, and I love to ski and windsurf.
