Nithin Devireddy, MD
Emergency Medicine Fellow
My name is Nithin Devireddy. I was born in Georgia and raised in Austin, Texas. I went to undergrad in Manipal, India and spent majority of my medical education in numerous states (7 states) across the nation. I graduated with an M.D. from American University of Antigua and went to University of Oklahoma Family Medicine Residency Program. I had a strong interest in Emergency and Sports medicine throughout medical school and continued seeking clinical experience throughout residency.
Being an outdoors enthusiast, choosing St. Anthony’s EM Fellowship inLakewood, was one of the most exciting adventures to come my way. I enjoy hiking, snowboarding, skiing, 14'ners, motorcycles, reading Sci-Fi, and watching all things related to Stargate/Star Trek/ Star Wars.
Leslie Guerrero, MD
Emergency Medicine Fellow
I am originally from Kalamazoo, Michigan, home of Bells Brewery, Gibson Guitars, and Stryker Medical Instruments. I grew up with a physician father, nurse mother, and two older sisters who now practice nursing and physical therapy. So, family certainly played a strong role in my decision to pursue medicine as a career. My interests in healthcare, particularly in family medicine, grew during my undergraduate education at Loyola University Chicago. Volunteering both at home in the city hospitals of Chicago, and abroad in a small clinic in Cuzco, Peru, I got to see the direct impact primary care has on disadvantaged communities. The same can be said for my experience at Michigan State College of Human Medicine, where I spent much of my time training in Flint, MI, infamously known for the recent lead water crisis. I completed my residency training at University of Colorado which prepared me to practice full spectrum medicine while focusing on patient centered care. I hope to continue promoting wellness for my patients and their community but also finding ways to make primary care more accessible to disadvantaged communities.
When I am not in the hospital or clinic I love to travel, and for years my husband and I have taken trips to Denver to go backpacking, hiking, climbing, snowboarding and skiing. My particular interests include landscape and portrait photography, so I have been taking advantage of all that Denver has to offer!
Hailey Holland, MD
Faculty Development Fellow
Hello! My name is Hailey and I was born and raised in Northwest Indiana. I attended Indiana University in Bloomington where I received my B.S. in Biochemistry, and then attended Indiana University for my M.D. I spent about a month in Denver during my last year of medical school and was amazed by the beauty of the state as well as the warmth & excitement of the people I’ve met. One of my greatest interests in family medicine is the physician’s role as an educator. I was so thankful to begin my journey at St. Anthony North Family Medicine Residency, a program with such an empowering patient-centered model. I cannot wait to start the next chapter of my life as a faculty development fellow at the St. Anthony North Family Medicine.
Kristen Otto, MD
Maternal Child Fellow
I a newcomer to the Denver area. Originally hailing from San Diego, CA, I developed a love of the outdoor life growing up, as well as a strong connection to people and community. While in undergraduate at USC (Go Trojans!) and in graduate school at Duke (Go Blue Devils!), I pursued studies in health-focused anthropology and religion. I was involved in women-centered
organizations throughout college, with a special focus on philanthropy and community outreach. My master's studies were in the field of global health, where I had the opportunity to pursue a thesis project around maternity care in Lima, Peru. Before returning to medical school at the Keck School of Medicine of USC (again, Go Trojans!), I worked on global health projects at the US-Mexico border, Guatemala, and Namibia. I was involved in obstetric, family medicine, and singing groups during medical school, and ultimately landed at Oregon
Health & Science University for my 4-year residency in Family Medicine. While in residency, I actively trained in surgical obstetrics and full-spectrum reproductive health and am excited to continue my training through the Maternal-Child Health Fellowship here at St. Anthony North! Though a family doctor at heart, I am driven to provide comprehensive obstetric services for my patients, particularly in Cesarean section.
When not in the hospital or clinic, I enjoy spending time with my husband and our three energetic dogs. I am always looking forward to my next adventure, whether local or international, and enjoy hiking, road tripping, scuba diving, concert-going, and singing. I am always happiest when near the water, enjoying country music, or spending time with those I love.
Shannon Mentock, MD
I completed medical school at Wake Forest University before moving to Denver for Family Medicine residency at St Joseph Hospital. I obtained my undergraduate degree in Nutrition and Public Health from the University of North Carolina at Chapel Hill. This background gave me an interest in preventive care and pushed me towards a career in primary care and Family Medicine. At St Joe’s, I found joy caring for new mothers and infants throughparticipating in the OB track and becoming a certified lactation consultant. I also participated in the integrative medicine track and tried to incorporate alternative medicine principles in my care whenever I can.
I am passionate about global health and traveling all over the world. Before medical school, I spent two years as a Peace Corps Volunteer in Cameroon where my main projects included health education and healthy cooking demonstrations. I speak French and spent time during residency in Guatemala to learn Spanish, which is improving every day. After fellowship, I plan to work in an underserved community through the National Health Service Corps.
Since moving to Colorado, I have spent most of my free time outdoors camping, hiking, and learning to ski. I am also trying to visit as many state and national parks as I can. I grew up in Durham, NC, but both sides of my family come from Wyoming, so I have been lucky to be able to spend more time with my extended family since moving out west. I stay in touch with my family in North Carolina by frequently video chatting with my two adorable little nieces. I am excited to continue training at St Anthony North!

Hello! I am a Colorado native who hasn’t found a reason to leave yet! I grewup in Pueblo and made my way north from there, including undergrad at CSU in Fort Collins, medical school at Rocky Vista University in Parker, and finally, family medicine residency at Saint Joseph’s Hospital in Denver. Ihave always had a strong passion for lifestyle and preventative medicine, which led me to pursuing further training in integrative medicine. I am therefore ecstatic to be staying another year in Colorado to complete myfellowship at Saint Anthony’s North. In addition to integrative medicine, my other areas of interest include women’s health, obstetrics, procedures and OMT.
When I am not working, you can find me hanging with my husband, Kurt, and our pups, Bear and Phoebe. We enjoy hiking, camping, paddle boarding, checking out all of the breweries Denver has to offer, and fitting in as many Rockies games we can.
