Meet our Fellows

Erin Finn








Erin Finn, MD
1st Year Fellow

I am a born and raised Coloradan, who has spent many years moving back and forth between Denver and Houston, Texas, where I attended college (Rice University) and did my residency (Internal Medicine-Pediatrics at Baylor College of Medicine). I am thrilled to be back in Colorado to pioneer a dual fellowship track in pediatric and adult endocrinology. The highly collaborate nature of Colorado and the Anschutz Medical Campus lends perfectly to dual training across institutions. I look forward to taking advantage of the strong research and clinical experiences that the University, the VA, Denver Health, and the Children's Hospital of Colorado all have to offer. In my spare time, I hope to take advantage of the location to ski, hike, and camp.

Jill Wagner








Jill Wagoner, MD
1st Year Fellow

Hello all! I was born and raised in Grand Island, Nebraska as the youngest of four girls. I attended our state university studying Biology and Anthropology. For medical school,residency, and Chief year I just couldn’t get enough of  Nebraska, so I stayed for another eight wonderful years in the Cornhusker state. (I am aware of the quality of our football team.) I am so overjoyed to join the dynamic and esteemed CU family. I wanted learn how to start over after 30 years in the same place, and after meeting the DEM faculty and fellows I knew this was the place I wanted to be to work hard and grow with new relationships. My hobbies include cooking, trivia, musical theater (watching not performing), classic movies, travel and hanging with my niece and nephews.

Rebecca Jeffers








Rebecca Jeffers, MD
1st Year Fellow

I decided to come to University of Colorado for my Endocrinology training because I was deeply impressed by the people and culture of this institution. Beyond participating in clinics dedicated to every sub-specialty within endocrinology, we will be training with world-renowned experts. I am also very excited by the sheer volume of research opportunities that are available. This was by far the best endocrinology program I interviewed for out of the lot.

Denver is also a city I have been eager to live in as I look forward to all it has to offer, especially the beautiful scenery, new adventure opportunities, and the vast amount of green space for my four-legged fur babies!

2nd Year Fellow

I chose the University of Colorado for the range of expertise of the faculty and diversity of pathology seen here. There is no aspect of endocrinology we don’t have plenty of exposure to. Everyone is very collegial and works together well, especially with all the sub-specialty expertise amongst the faculty.

The weather and scenery can’t be beat!

Greg Schleis








Gregory Schleis, MD
2nd Year Fellow

I chose the University of Colorado for fellowship training for the mix of faculty and diverse training opportunities. When I went to different conferences, it always seemed that someone from the University of Colorado was presenting or wrote the paper on the topic. During my interview, it also felt like a place I could thrive and learn from some of the best experts in the field.

My favorite part of the program is the ability to work with many different experts in each field all of which are very approachable to any question. The faculty is focused on teaching and want to make sure you learn as much as possible.

Denver is a great mix of what I love in outdoor activities. You are close enough to almost anything on the weekend and get away yet have all the benefits of a large metropolitan area. Generally, people are nicer than I’m used to experiencing.

Raj Bhalla








Rajat Bhalla, MD
2nd Year Fellow

I chose the University of Colorado because it is a nationally renowned division and large faculty. I also enjoy the excellent training and education provided along with committed faculty, and collegial fellows. I also like the opportunities for skiing/snowboarding and hiking. In addition, Denver offers pretty much everything.

My hobbies include tennis; fitness; watching sports and snowboarding.

Layla Abushamat








Layla Abushamat, MD
3rd Year Fellow

I was drawn to the University of Colorado for the exposure to a variety of pathology, both common and rare, as well as the ability to see multiple practice settings in action. Additionally, I was impressed by the level of expertise of the faculty. Everyone is so approachable and collegial. The faculty are engaged in our education and are very supportive. I love the proximity to the outdoors, as well as the variety of cultural activities accessible within the city. It is a great mix of nature and city living. I love spending time with family and friends, reading, and cooking.

Adnin Zaman








Adnin Zaman, MD
4th Year Fellow

Having completed all of my undergraduate and medical training in Los Angeles, CA at the University of Southern California, I was interested in diversifying my experience. I selected the University of Colorado for my fellowship training given the breadth and depth of the experiences here. We see a variety of endocrine cases in varying stages of each disease, so the clinical experience is great. My favorite part of the program is by far the exemplary faculty we get to work with. Everyone is so knowledgeable about the field! Since we are a tertiary referral center, we see rare diseases as often as we see bread and butter endocrinology; it’s so amazing to learn from the experts.

The research here is also robust with faculty doing projects in every imaginable subspecialty within endocrinology. My specific research interests are in women’s health, PCOS/infertility, and obesity. My main project is with Dr. Victoria Catenacci looking at how combined hormonal contraceptive use by pre-menopausal women might affect weight loss and weight loss maintenance within a behavioral weight loss program
comparing intermittent fasting to daily caloric restriction. I had little to no experience in research before coming here, but the amount of support I have received from the Division has really been phenomenal.

Finally, Colorado has been a wonderful place to live. Everyone in Colorado has been so friendly! It’s been nice to explore a city where you can enjoy all four seasons both indoors and outdoors (though I mostly stay indoors exploring restaurants and going to concerts).
