Caldwell RTT

Welcome to the Caldwell Rural Training Track (RTT) Family Medicine Residency. The RTT is a branch of the main Family Medicine Residency of Idaho Program that is designed especially for broad-spectrum rural family medicine training. Here in Caldwell, our faculty is passionate about the training of Family Medicine Physicians. We are an unopposed program supported by the entire medical community of Caldwell and the surrounding areas. Therefore, we are able to provide an extremely broad training experience for our residents. Trainees essentially become a member of the medical group when they come to Caldwell as a resident, allowing for great professional and personal flexibility. This is very important because we recognize that balance is necessary to make well-rounded, fulfilled physicians.

The Caldwell RTT began in 1995 with one resident per year, graduating our first resident in 1998. In 2006, due to the program’s success, it was expanded to two residents per year (six residents’ total). In 2011, once again, the program expanded to three residents per year (nine residents’ total). All of our graduates are board certified family medicine physicians. Of our graduates to date, 88% are serving in rural areas.

The first year of training is completed in Boise with the core residency program. The second and third year residents complete their training in Caldwell (about 30 miles west of Boise). Medical students interested in the Caldwell program must submit an application through ERAS separate from the Boise application. Applicants invited to interview in Caldwell will also be interviewing in Boise on the following day.

Peter Engdall, MD

Caldwell RTT 2021

I grew up in Albany, Oregon, in the heart of the Willamette Valley. Here I developed a love of community and service while being active in many school program, earning my Eagle Scout rank, and even developing a few clubs of my own… all while finding ample time to camp, play sports, and play in the outdoors.

I moved to Eugene, Oregon, when I was 18. While there, I spent many years managing a few local restaurants. Later on I started volunteering for a small rural fire department in Dexter, Oregon. It was this experience that started me on a path to medicine. I started as an EMT, and then went back to school to become a paramedic. I worked as a Paramedic for several years in Multnomah County, which includes the cities of Portland and Gresham.

With the encouragement of my future wife, Corena, I eventually went to Portland Community College, then Portland State University. I earned my degrees in both General Science and Organismal Biology.

I had the good fortune to attend Oregon Health Science University. In medical school I found my true calling in Family Medicine and serving rural communities like the one I grew up in.  I worked hard to promote primary care in rural settings. For my efforts, I was selected to join the Gold Humanism Society. I was further humbled by my class and faculty, when they selected me to be the recipienof both the Swindells Family Scholarship and Leonard Tow Humanism Award.

I am thrilled to have the opportunity to train in the legendary Caldwell Rural Training Track for the Family Medicine Residency of Idaho.

With me on this journey are Corena, my wife, and our son Gus, born only a few months before we moved here.

I can’t wait to serve this community while learning the art of medicine, all while watching my son grow and my wife continue her dream of training horses, in this beautiful area.

Travis Griffiths, MD

Caldwell RTT 2021

My wife, Quincey, and I both hail from Salt Lake City, Utah, and are the proud parents of one little girl with hopes for more in the future. I attended college at Utah Valley University and graduated from the Honors Department with a Bachelor’s degree in Spanish.

After college, I attended medical school at the University of Utah where my “plans” for residency varied from Pediatrics to Obstetrics to Orthopedics. I knew I wanted to have a broad scope of practice and continuity with patients, but also wanted the fulfillment that came from intervening on acute medical issues. Thus, I dual applied to both full-spectrum Family Medicine as well as rural General Surgery programs.

I was very impressed by FMRI because I felt that I had found a program where I would be surrounded by people who shared my interests, and where I could get the broad training I was looking for. My interests in medicine include rural health, obstetrics, trauma and emergency medicine. Outside of medicine I love to spend time in my garage gym, getting coached on full-depth squats by my 3-year-old. I have been known to geek out when talking about personal finance, and am an outdoor enthusiast who looks forward to hunting season every autumn.

Tyler Starr, MD

Caldwell RTT 2021

Tyler was raised in the Treasure Valley on his family farm in Ontario, Oregon. He attended Treasure Valley Community College and Boise State University for his undergraduate degree. Tyler went to Ross University for medical school. Prior to his medical career, Tyler worked on his family farm, built homes, and did road and bridge construction. He enjoys spending time with his family, exploring the outdoors, and is often busy working on home improvement projects. He is excited to join the Family Medicine Residency of Idaho. Tyler is accompanied by his wife Holli, and three sons Ethan, Sam, and Levi.


Ammon Roberts, DO

Caldwell RTT Program 2022

Ammon was raised in a family of nine kids on a potato and onion farm in Eastern Oregon. Growing up in a large family on a farm instilled in me the importance of hard work and perseverance. I remember working long days in the blistering heat until my muscles ached. At times, I felt I could not continue, but I knew that my family relied on me as a vital member of the team to accomplish our goals. During those especially long days, my father engrained in me a tenacity to accomplish and persist through even the most difficult of circumstances.

My health care experience prior to medical school was primarily in emergency medicine. During my time as an emergency room scribe, I participated in a team that helped people during their critical moments. This gave me an appreciation of the impact a physician has in the lives of our patients, and their families. I also came to realize the importance of teamwork and team inter-reliance, especially during stressful and busy times.

During my time in clerkships, I found that I really enjoyed taking care of people, especially those that had similar backgrounds as myself. My family medicine rotation was in a small rural underserved community, very similar to the one I had grown up in. Many of the patients that I was seeing had little medical knowledge and felt helpless and overwhelmed when dealing with the complexities of health care. They looked to us for help, and I soon found my own niche, as I became an advocate for them by providing skilled and complete health care.

My unique background, education, and life experiences have guided me into a career in family medicine. I feel family medicine would bring out the best parts of myself and help me achieve my future life goals of living and caring for people in a rural community. I look forward to being part of team where I can be a valuable member to help bring quality health care to our community.

As I strive toward becoming a family medicine doctor, I seek a residency program where residents support each other and work in harmony as a team. I look forward to the opportunity of caring for patients in a meaningful way and hope to perform as an emissary for the residency program I join. I am eager to learn the skills necessary to become an exceptional physician in an ever-evolving field, and to gain the knowledge that will aid my future patient care.


Ashley Carvalho, MD

Caldwell RTT Program 2022

Ashley was born and raised in Boise, ID, and attended the College of Idaho in Caldwell where she majored in biology and history. She had the opportunity to spend her junior year in Ireland as an exchange student, and after graduation, she returned to Ireland to do a Masters in Public Health at Queen’s University in Belfast. She loved it so much, she decided to stay at Queen’s for medical school. During her training, she had opportunities to complete international rotations and learn about healthcare systems in other parts of the world, including the UK, Ireland, Australia, and Peru. Not only did she gain valuable insights and perspectives on global and international health during these rotations, she also saw many amazing places – all the way from Macchu Picchu to the Harbor Bridge in Sydney, Australia.

While abroad, she made many wonderful friends who became her family. The welcoming and tightly-knit communities she was a part of in Ireland reminded her of home, and this inspired her to return to Idaho to practice family medicine in the community she loves so much.

Some things Ashley likes to do for fun: explore the outdoors (including the many hiking trails and hotsprings Idaho has to offer), run local races, cook and bake, travel (next on her list: Iceland and Japan), play board games, read anything and everything, go to trivia nights, play piano and ukulele, and play with her black lab, Tuck!

Ashley is thrilled to be back on Idaho soil and is so excited to be joining the FMRI family!

Stephen Richardson, DO

Caldwell RTT Program 2022

I’m proud to be a native of the beautiful Pacific Northwest. I was raised in Camas, WA  near the scenic Columbia Gorge, where I first developed a love for the outdoors. I spent a significant portion of my childhood camping amongst the Douglas Firs, hiking up Cascade peaks, spelunking through volcanic caves, and running through the forest trails behind my house. To this day, whenever I have a free weekend, there’s a good bet I’ll be heading out to the great outdoors.

Having a close brother with epilepsy introduced me into the medical world. Days, sometimes weeks, spent with my brother in the hospital were not unusual. From check-ups to extensive brain surgeries, I have been there with my brother. I saw the impact that physicians can have in the life of a patient. That has been a significant motivator for me on my pathway to where I am now.

After serving a mission for The Church of Jesus Christ of Latter-day Saints, I attended Brigham Young University where I earned my degree in Neuroscience. Medical school brought me back to the Pacific Northwest, where I attended Western University of Health Sciences COMP-NW. I knew from an early point that family medicine was where I wanted to end up. I value relationships and felt that this is where I could make the most impact, so I volunteered in rural, underserved clinics during medical school. After completing a sub-internship in Caldwell, I was thrilled to match with the Family Medicine Residency of Idaho – Rural Training Track. I look forward to serving the people of Idaho.

Just a little bit more about me – one of my hobbies is collecting more hobbies. I enjoy (in no particular order) running, hiking, weight-lifting, architecture and design, gardening, home construction/renovation, singing, playing the piano, painting, serving in the community, reading, mountain-climbing, traveling, cooking, church activities, humanitarian work, woodworking, whistling and probably a few more.

Lauren Hanlon, DO

Caldwell RTT Program 2023

I was born and raised for most of my life in Ventura, CA. I came from a family of competitive swimmers and all-around water lovers so I had the privilege of spending most of my life in and around water. I swam competitively for 15 years, ultimately swimming for the University of Redlands women’s swim team. While at Redlands, I majored in Biology and minored in Chemistry and Spanish. I was also fortunate enough to meet my husband Ryan during our freshman year, and we have been together ever since. Between undergrad and medical school, I wanted to experience the world outside of my comfort zone and improve my Spanish language skills. Ryan and I lived, worked, and traveled in Chile and Argentina for seven months. We met extraordinary people, saw some of the most beautiful places in the world, and thoroughly enjoyed our time there. After returning from South America, I was accepted into medical school at Pacific Northwest University (PNWU) in Yakima, WA.

My medical interests include: Osteopathic Manipulative Treatment (OMT), Sports Medicine, Women’s Health, and Emergency Medicine.

Some things I like to do for fun: I now compete with the Boise Barbell Olympic Weightlifting Club in Boise. I love being part of the tight knit group and continuing to improve my strength and technique. I also love anything to do with water (as mentioned above), hiking with our dog, Max, being the pack mule during Ryan’s triathlon races, and sampling Ryan’s new cooking masterpieces.

I am so excited to be part of the FMRI family!

Dr. Bill Brandenburg: What I like about Caldwell RTT:
FMRI Caldwell RTT gave me the training I needed to go to rural hospitals and practice a broad scope of care including pediatric, adult, obstetric, and critical care medicine. Caldwell's unopposed residency gave me the freedom to move around the hospital and gain incite from many different specialty providers, nurses, and therapists. This allowed me to become a real full scope physician.

Clinical Locations

Saint Alphonsus Medical Clinic

315 East Elm Street, Caldwell, ID 83605

The Caldwell RTT site is based at Saint Alphonsus Medical Clinic which is a large group of ten family physicians and five pediatricians. The clinic is located in a 56,000 square foot office building physically attached to West Valley Medical Center in Caldwell. This close proximity allows residents to go back and forth between the clinic and the hospital with ease, helping them to be involved with any interesting cases that may be going on in either location.

West Valley Medical Center

1717 Arlington Avenue, Caldwell, ID 83605

Hospital duties during years two and three will be performed at WVMC. West Valley is a 150-bed (ten critical care beds, seven intermediate care beds, eight pediatric beds) community hospital that has been serving the community well for over 50 years. Residents are welcome to gain experience in the entire hospital. They can commonly be seen in the busy ER, the endoscopy suite, the critical care unit, the OR, and even the cardiac catheterization lab. Food is provided for residents in the cafeteria and doctor’s lounge free of charge. The hospital is small enough that one can quickly learn everyone’s name, and large enough to provide a broad experience for trainees.

Idaho Surgery Center

3115 Medical Drive, Caldwell, ID 83605

A number of physicians in our group spend time performing endoscopic procedures at the nearby Caldwell Surgery Center, outpatient surgical facility owned by MVMC. Our local surgeons spend time at the Center as well, and residents receive privileges there, enabling them to participate in procedures when time allows.


Caldwell is the first town and western entrance to the magnificent and picturesque Treasure Valley and is located on the beautiful Boise River. The city is situated in an ideal location between he Owyhee mountain range to the southwest and the Sawtooth range to the East which provides  ample camping, hunting, fishing and other outdoor activities.

Southwest Idaho is also well known for its whitewater rafting, multiple ski resorts, great hiking trails, mountain biking, and awesome camping and fishing locations. 

Or try your luck panning for gold in Silver City, one of Idaho’s historic mining towns located just south of Caldwell.  In addition to being so close to the great outdoors, Caldwell is just 30 minutes west of Boise, which is Idaho’s capital and home to cultural events, shopping, entertainment, restaurants, the Boise philharmonic and a yearly Shakespeare Festival.
