Josh and Amanda

After being born here at TMC myself, Tucson has always been a home to me and my family. I grew up a Wildcat and was lucky enough to meet my beautiful wife Amanda in senior English class at University High School. We both studied here at the U of A as well where I completed my Bachelors degree in neuroscience as well as my medical degree at the College of Medicine. After a quick trip to train at one of the nation’s top children’s hospitals at Nationwide Children’s Hospital in Columbus, OH, I am thrilled to bring back my experience and perspectives to our Tucson community.  

Josh and Family

I was inspired by my parents before me to practice medicine, but especially my mom, who still serves the Tucson community as a practicing OB/GYN. After she helps guide new parents through the process of welcoming a new child, she passes the torch to me to help care for the newborn and beyond.  

I’m honored to be joining the Mesquite Pediatrics family where we can truly take time to serve our patients and families. I wanted to join a practice where I can offer consistent and easily accessible care to my patients. I hope to champion our families first values and provide comprehensive care to support our children to the best of our abilities.  

Josh and Amanda Outside of work, my wife and I love to cook and bake together, and we are always looking for new restaurants to try and gobbling up any cooking show on Netflix we can find. We also love to enjoy the outdoors and spend time walking, hiking, and rock climbing throughout our beautiful state.

I was born near Detroit, Michigan, which I always say is a good place to be FROM (I'm very happy now to be living in Tucson, instead). I went to undergraduate school at the University of Michigan, mostly because it was where all my friends were going and I didn't want to fill out any more college applications. For medical school, I did a little more searching and ended up at Washington University in St. Louis. I enjoyed St. Louis but, though it's both south and west of Detroit, it still wasn't what I had in mind. When I finished medical school, I interviewed throughout the West and chose to do my residency here in Tucson, at the University of Arizona. I fell in love with Tucson during those three years and decided to make it my permanent home.

When I finished my residency, I was fortunate enough to fill a vacancy at an established pediatric practice, where I then worked for seven years. But, after being in practice for a while, I decided that I'd like to do things differently and I needed more flexibility. So, Dr. Mary Cochran and I opened Mesquite Pediatrics at the beginning of 2006. We created a small practice that is peaceful, efficient, and unrushed. I like having time with my patients; our staff is happy, friendly, and helpful; and I feel our patients get the attention and respect they deserve. My goal at Mesquite Pediatrics is to provide every one of our patients with high quality medical care and to make sure that we meet everyone's needs as much as we possibly can. Finally, I want to make sure that our patients and their parents learn everything they can about their health. I don't ever want people to leave an appointment with questions that haven't been addressed.

I have many interests outside of pediatrics. My wife, Leigh, and I were married in May, 2002 and we have two boys: Eli, born in 2003 and Zane, born in 2010. My wife and I met playing volleyball and we still lead an active lifestyle with cycling, hiking and swimming. I have played soccer all my life, currently playing in a coed league and an over-40's men's league on weekends. I am also a triathlete and completed an Ironman in 2021.

Rumor has it that there are not many native Tucsonans but I am one of them. I live in the neighborhood where I grew up, less than a mile from Mesquite Pediatrics. My dad would often quip about life in Tucson as "another day in paradise" and I share his view. I never tire of the view of the Catalinas and cannot imagine shoveling snow on a regular basis.
Growing up, I always wanted to be a doctor but pediatrics is actually my third career. After getting my Masters Degree I worked in a lab at theU of A in Exercise Physiology. I was coaxed into coaching soccer at Ss Peter and Paul and at Salpointe which led me to my second career as a high school teacher. The seven years I spent teaching science and coaching were fun and rewarding.

Finally, I returned to my dream of being a physician. I went to medical school at the University of Arizona never planning to become a pediatrician. However, at every step of my training I was pointed towards taking care of kids. I did my pediatric residency training at Phoenix Children's Hospital and Maricopa Medical Center. In 2003 I returned to Tucson to work for El Rio Health Center where I had a large panel of my own patients and was involved in teaching medical students and residents at my office and in the hospital.

In 2011 I had the opportunity to join Drs. Cochran and Couchman at Mesquite Pediatrics and have met many wonderful families. My years as a teacher have come in handy as much of pediatrics is often more about educating parents than it is curing a child. I share my colleagues' goals of providing quality, timely care to our patients.

In my free time I play soccer and ultimate frisbee, routinely lose ten dollars in my monthly Texas Hold 'Em game and always enjoy a weekend on the beach at Rocky Point.

I am proud to be a native Arizonan, born in Phoenix and raised in the scenic locale of Cave Creek, Arizona. I moved to Tucson in 1999 to pursue my undergraduate degree in Physiology at The University of Arizona. Falling in love with Tucson during my undergraduate years (as well as my husband, Nick), I’ve permanently settled in this beautiful city. As a die hard Arizona Wildcat, I was thrilled to be able to complete my medical school training, Pediatric Residency, and a year as Chief Resident of Pediatrics at The University of Arizona (Go Cats!).

Nicole and Family

After completing my Residency and Chief Resident of Pediatrics year, I joined the Pediatric faculty at The University of Arizona/University Medical Center. I relished teaching medical students and residents and thrived on seeing these budding physicians grow and learn under my guidance. In the last three years of my academic career, I became the Medical Director of the newborn nursery Banner University Medical Center (formally UMC). I particularly enjoyed taking care of both the mother and the newborn infant during this crucial time.

Nicole and Kids After almost seven years in the academic setting, I realized that the additional non-patient related responsibilities associated with an academic career were rewarding, but were keeping me from focusing on what I love most, taking care of patients. Making this realization, I was thrilled to be offered the opportunity to join Mesquite Pediatrics. I was personally drawn to Mesquite Pediatrics due to their uniqueness in offering care in a smaller, more patient-orientated practice that would allow me to provide the best quality care for my patients and their families.

Outside of the office, I enjoy reading, exercising, traveling, and spending time with my wonderful husband and two very active children (Logan and Caitlin).  Logan is an excellent student, enjoys a good chess match, and is a successful gymnast placing in the top 3 all around Level 7 for his age in the country in 2024.  Caitlin enjoys creating art masterpieces, playing the viola, and is a great gymnast as well.  Our family enjoys outdoor activities including camping and snow skiing. In addition, my husband and I are die-hard University of Arizona Athletics fans, but most enjoy attending Men’s Basketball games.
