Mark May, MD

MarkrappelingMark joined UES in 1993. He graduated from Michigan State University with a BS in Anthropology and later an MD. He did a rotating internship at Camp Pendleton Naval Hospital and then spent 6 months training as a flight surgeon. He was a Naval flight surgeon for four years prior to doing his EM residency at Butterworth Hospital in Grand Rapids, MI. UES was his first stop after residency. He is the current Chief of the Medical Staff and has also served in the past as the ED medical director and the EM department chair. 

“I was a charter member of EPIC and over the years have seen the benefits of so many emergency docs joining together so we are better represented in contract negotiations among other things. I have reaped the benefits of being a member of UES and EPIC.  Being part of a truly democratic group is rare in EM medicine today but really worth it if you can find such a group. My wife and I brought our family to Utah right out of residency, thinking we would just stay a few years but Utah has so much to offer that we have never left due to being able to enjoy our outdoor interests and having a safe place where we can raise a family.”

Dr. May enjoys mountain biking, trail running, camping, and backpacking.

Diane Ruschke, MD

dianeyogaDiane joined UES straight out of residency in 1993. She graduated with a BS in Biomedical Engineering from Northwestern University and attended medical school at Rush University. She then spent four years training in emergency medicine at UCSF Fresno. She has held positions as the quality assurance manager for the group and started the mid-level program for the group, doing the original hiring and practice guidelines. She says, “You can work in many types of groups for the short term. But if you want longevity in a full time EM career you have to like and respect your colleagues and feel you contribute to and have control of your daily job and future. These were our goals when we started to create UES and EPIC.  I believe we have succeeded in reaching those goals and continue to work on them daily.”

DianefamilyDr. Ruschke enjoys skiing of all types, international travel, white water rafting, spending time with her family, mountain biking and especially long distance cycling. She once spent a year cycling a tandem through Australia and New Zealand and has done Ride the Rockies, Cycle Oregon, and ridden through Nova Scotia and the entire West Coast of the US. “Utah is ideal for outdoor proximity for daily activities with the added benefit of city amenities especially the Arts.”

Andrew Florence, MD

He did his undergraduate work at Duke, attended medical school at Georgetown and completed his residency at the Hennepin County Medical Center Emergency Medicine Residency Program. A prior department chair, he now serves on the hospital credentialing committee.

Dr. Florence appreciates the EPIC structure because of the “exceptional CEO with physician interest at the forefront and the great relationships between the other divisions within the broader organization.” Regarding working in the UES division, he says, “We IMG_5624have two great hospitals to work in with very balanced patient populations, excellent nurses, and a perfectly collegial atmosphere.  The group is an ideal size for physician input and for building strong relationships.  UES partners choose the shifts we want to do, so nobody ever complains about the schedule.  We all work the number and type of shifts that we prefer.   It is a fantastic place to work for an entire career.”

Andrew loves to mountain bike, ski, and vacation with his wife and children.

Imlay CanyonOutside interests include rock climbing, mountaineering, canyoneering, mountain biking, downhill skiing, ski touring, ice hockey, Scouting, boating, and spending time with his wife and four children. His favorite part about living in Utah is the easy access to the Wasatch mountains and dozens of national and state parks. “There are few other places where you can get a half day of skiing in on the same day you work a shift.” He feels that the EPIC structure offers the “best of both worlds- a large group when it comes time to negotiate with payors, hospitals, and benefit providers, but a small group when making all of the decisions that affect your practice, income, and lifestyle.” He welcomes questions about the group at drdahle (at)

Teanu Mataoa

IMG_3788Teanu came to UES in 2015 after working for several years in the San Diego area. He graduated from BYU in 2003 with a BS in Human Biology, and received his MD from the University of Utah in 2008. He trained for the next four years in the Yale New Haven Hospital Emergency Medicine Residency Program. His professional interests including Global Health and Emergency Ultrasound. He says, “After working as an independent contractor for a large corporate group, the change of pace with UES and the culture of the practice is so much more enjoyable and in the long term, more sustainable. No risk of burn out. I really appreciate working in a democratic group with partners who are easy going and approachable. It makes checking in for a shift something you can actually look forward to, and not have to worry about whether you are going to get crushed or slammed. Everyone works together and makes important decisions as a group of partners. We answer to ourselves, not the corporate boss. I feel like I can practice Emergency Medicine the way it should be in a safe and manageable practice that I can invest my career in.”

Teanu enjoys soccer, running, surfing, mountains, and the ocean. However, despite his love of the ocean, he also loves Utah for its great community, its proximity to his family, the affordable cost of living, the plethora of outdoor activities especially in the mountains, and the excellent and free public school language immersion programs.

Kate Pino, MD

KateworkKate joined UES in 2014 straight out of residency. She graduated from Weber State University with a BS in Zoology in 2007 and then from the University of Utah School of Medicine in 2011. She did her EM residency at UT Southwestern in Dallas, Texas and then returned to Utah, her original home.

“I was excited to return to Utah and feel there is no better place to raise a family. I have felt very fortunate to be a member of UES. Every member of the group is accomplished and hard working but also able to maintain a work-life balance, which is very important to me. It has always been nice to feel supported at work. We have great hospitals where we work closely with the nurses and staff that I consider as Katefamilyfriends. I am grateful to be a part of the group and feel lucky to have chosen to work in a democratic group, which seems to be a rare thing to find in many areas. We enjoy the perks of being a part of both a large group with EPIC but also a smaller group as UES. I always feel my individual needs and concerns are able to be heard but also have the support of a large EM group. I love working with this group and feel that this job will be my first and last.”

Dr. Pino is married to David and they have two young girls. She enjoys reading, running, tennis (which she played in college,) and spending time with her family.

Ryan Giles, MD

ryanworkRyan joined UES in 2001. He did his undergraduate work at the University of Utah and then completed medical school at New York Medical College before completing his EM residency at Parkland Hospital in Dallas Texas. He currently works as one of our nocturnists, working all night shifts. He considers his professional interests “being a good team member.” He loves the EPIC structure because “Doctors are historically poor businessmen / investors. Most cannot be a great physician, run a medical group, and be a parent at the same time. One has neither enough energy nor time. EPIC has well ryansubwaytrained management who negotiate contracts with insurance companies and hospitals on my behalf. That means more money so I can buy more free time. Just as my plumber fixes a toilet better than me; EPIC negotiates a contract better.”

Dr. Giles enjoys any activity in the wilderness with solitude including skiing, climbing, canyoneering, and mountain biking with friends and family. He notes that “Utah is the only place you can have a full-time career, full-time outdoor life, and be a full-time parent. It is the best place in the world. I love UES. My colleagues are also my friends. It would be difficult to find a better group.”

David Swenson, MD

DavidworkDave joined UES in 2015 directly out of residency. He graduated from BYU with a BS in Chemistry, then completed medical school and an MPH in 2012 at Ohio State University. He did his EM residency at GRMEP in Grand Rapids, MI. His primary professional interest is ultrasound. He loves being in a “democratic organization that helps me have a say in my practice” and notes that “all of my colleagues are awesome. We cover or switch shifts to help each other out and everyone seems dedicated to patient care and is supportive of other group DavidFamilymembers.” 

He enjoys racquetball, running, golf, soccer, disc golf, and playing with his kids. His favorite part about Utah is the “people I work with and all the many activities available to participate in with my family and friends.”

I enjoy coming to work and seeing my friends.  It is not unusual for four or five of us to go mountain biking or skiing together.”

Dr. Dahl is married and has 2 children.  She enjoys trail running, mountain and road biking, back-country and nordic skiing, yoga, playing the piano, gardening and baking.

He says that “The character and personality of the individuals in the group is what I love about UES.  Soon after I was hired I asked a question and was surprised and pleased to hear the reply-‘We just want you and your family to be happy.’ I feel that my longterm wellbeing and happiness is a priority for the group. I love the opportunity to be involved and joshplaytruly have a say in my practice. I am more than just an employee punchin’ the clock.”

Dr. Parker enjoys backpacking, fishing, running (which he also hates), crosswords, soccer, and raising his six children. He loves “the four-season climate and access to outdoors and the unique culture of Utah.”

He then completed his emergency medicine residency at the University of Arizona, South Campus in 2015. His professional interests include public health, ultrasound, and EMS. He appreciates that “EPIC is the best possible situation for emergency medicine. It’s large enough to be influential in the region, but each group is autonomous and democratic.” He loves the comraderie and support within the UES division. “All the members are exceptionally bright and energetic. Every member’s opinion is valuable and considered in decision making. I have heard many nurses say they’re the best doctors they have ever worked with. It’s truly an honor to be part of this group.”


Jordan enjoys skiing, hiking, basketball, reading Jim’s blog, and is a talented musician- playing guitar, piano, bass, and drums. He loves living in Utah due to the courteous and kind people, the peaceful community in which to raise his kids, and the mountains right in his backyard.
