Jamie Bonner, M.D. — R3
Ross University


I was born and raised in Morrice, Michigan.  I attended Indiana University South Bend and was a member of the Women's basketball team.  After graduating with my nursing degree I worked as a Trauma ICU nurse for 6 years.  I then decided to attend Ross University School of Medicine and have always known that I wanted to pursue Emergency Medicine.  In my free time I enjoy traveling, anything outdoors, live music, watching/participating in most sports and spending time with my friends and family.  I am excited about making new friends within the WSU family and for what the next three years bring.

Phil Griffith, M.D. — R3

Phil Griffith is a simple country doctor, who is just trying to make it in Big City Dayton. With his gang of fellow doctors and his mystery mobile minivan, he stamps out disease, fights evildoers, and solve crimes.

Born and raised in the Old Dominion, Dr. Griffith then lived in “New Hampsha” for a bit, attempting to make computers talk to each other. Once Skynet reached operational status, he decided to retire and go to medical school. He also joined the USAF at that time, because, going to medical school, moving, and having a baby weren't enough of life changes.

He frequently pals around with his two boys, as well as his wife, who has nothing better to do with her time.

He enjoys backpacking, hiking, and rock climbing. With a trail name of “False Hope” who wouldn’t want him as their doctor? Unsurprisingly, his medical interests include wilderness medicine. He also enjoys toxicology, which has nothing to do with his enemies list.  

Finally, in all seriousness, Phil chose to come here for his military residency because he believes the hybrid civilian military model provides the best training to be the best doctor you can be. Plus, you know, biking, and Young's Dairy Bar!

I grew up in Northern Virginia, went to undergrad at the University of Virginia and medical school at Uniformed Services University with the Air Force. After a PGY1 internship in General Surgery at Wright-Patterson, I served as a Flight Surgeon in New Jersey with both heavy transports and helicopter crews. I deployed a few times to Africa and Southwest Asia. Now, I’m back in Dayton for Emergency Medicine.

On my days off, I enjoy marksmanship, painting, enjoying new restaurants, and occasional bar trivia.

My wife Allison and I were both raised in southern Indiana, but we've spent the last few years in Wisconsin for medical school. We have a 1-year-old boy named Micah, and the three of us enjoy doing just about anything outdoors.

Owen Scott, M.D. — R3

I spent the last 6 years before residency as an Air Force Flight Surgeon, which involved some very fun and interesting experiences.  My wife, Angela, and I have 3 kids.  My favorite things outside of work are traveling, being outdoors, hanging out with friends, and enjoying new craft beers and wine tastings.  On my days off, when I'm not sleeping, you may find me enjoying these impressive Dayton bike trails or riding my motorcycle.  Long-term plans include more Air Force deployments, traveling, hopefully some overseas assignments, and humanitarian medicine.

Anthony Bertasi, D.O. — R2
Nova Southeastern University College of Osteo Med.

I was born and raised in Memphis, TN where I grew up backpacking and canoeing in the nearby Ozark mountains. I later attended the University of Tennessee in Knoxville and graduated with a BS in mechanical engineering. After working for a few years in Kansas I decided to leave engineering, get married, and start medical school in Fort Lauderdale, Florida. Had a great time in Florida sailing a Hobie cat, kayaking and exploring the everglades with my wife Christine, my daughters Catherine and Lucia.  We are now happy to be in Ohio for residency. After residency we will see what the Air Force has in store!

Jeremy Brenneman, M.D. — R2

I grew up in Northern Virginia just outside of Washington DC and did my undergrad at UNC Wilmington where I met my wife, Kristen. Through senior year of high school and college I worked first as a volunteer EMT then Firefighter/EMT. After graduation I enlisted in the US Air Force and served 5 years working Crash Fire Rescue; training in Texas then stationed in Italy, Louisiana, and North Carolina. I commissioned in 2013 and returned to DC for medical school at USUHS where my wife and I finally tied the knot and started our family before moving to Dayton. In my time off I enjoy hanging out with the family and friends, doing just about anything outside (ideally at the beach but braving it out here in OH), traveling, reading, and photography.

Jared Brown, M.D. — R2
University of Colorado UC Denver

Beard gone but the girl decided to stay.

Grew up an Air Force brat, but my family was able to settle down in Colorado Springs. I have lived in Colorado for of 18+ years so it’s where I call home…still getting used to the lack of mountains out here. I did both undergrad and med school in CO at the Air Force Academy and CU School of Medicine respectively. Going to the academy I had quite a debate about my career choice: pilot or a doc…I think I made the right choice!

I am very excited to be here in Dayton doing a joint military civilian EM residency. My wonderful fiancé (soon to be wife just 4 months into residency), Noelle, is joining me on this new adventure. No kids, no pets, and no plans to change that soon; Noelle would say differently but we’ll see how busy residency is :) Ultimately I can’t wait to be an emergency doctor for the Air Force!

Interests: anything outdoors, hiking, camping, skiing, traveling to South America, art, woodworking.

Fun Fact: I am the oldest of 8…sorry if my older brother bossiness ever comes out.

I was born and raised in Las Cruces and Albuquerque, New Mexico, so spicy food and mountains are in my blood. I met my husband Tom in 2007, and after 3 years of marriage and living in 5 different states, we are so excited to settle down in Ohio! In my free time, I enjoy traveling (either home to NM to visit my family, or elsewhere), cooking, eating, hiking, hanging out with my dog (Pan) and cat (Leo), and craft beer/wine.

Adrienne Krysiak, M.D. — R2
University of Oklahoma College of Medicine

I did my medical school training in Oklahoma. It was there that I met my husband, Rick. His Air Force career took us to Dayton and we couldn't be happier! I love spending time outdoors and especially enjoy hiking, rock climbing, and cycling. Whenever I have a free afternoon, I love binge watching shows like Futurama and Great British Bake Off. My ten-year plan is to finish Gravity's Rainbow and take a 10 hour nap.

I am from Arizona, where I met my wife and attended college. My wife and I both attended Arizona State University, and I subsequently attended Arizona College of Osteopathic Medicine for medical school. After medical school I completed a General Surgery Intern year at UC Davis (hence the Golden Gate bridge photo). I enjoy spending time with my wife and the three rowdies, hiking, fishing, and kayaking. I am interested in out of hospital cardiac arrest and EMS, and look forward to exploring those topics further during my residency.

Megan Dillon, M.D. — R1
University of Kentucky College of Medicine

I was born and raised in Dayton, then left for Kentucky 8 years ago. There, I found my hillbilly geek of a trophy husband, and together we've come back to Dayton, Ohio to start my career in Emergency Medicine!

I went to UK and was a part of the Rural Physician Leadership Program, where I spent my 3rd and 4th years out in rural, Eastern Kentucky (Morehead, KY). I have a love for rural medicine and hope to be practicing emergency medicine out in the sticks one of these days. 
I'm a woman of many passions and hobbies. I love playing fantasy football, cooking, gardening, persecuting the critters that inevitably ruin my garden, canning whatever I manage to salvage from my garden, going for motorcycle rides, watching Game of Thrones with my grandma, going to the occasional Comi-Con, and of course watching Bob's Burgers with my husband (our favorite show, hence the picture). 
I love teaching. I love critical care. I love ultrasound. So who knows what the future has in store for me.

I'm a Dayton native and happy to be back home completing residency in the city I grew up in. I did my undergrad at Ohio Northern University and medical school training at Ohio University. I married my high school sweet heart (Beavercreek battling beaver alums) after ten years of dating. In my free time I enjoy hiking and all things outdoors, petting other people's dogs until we get our own, making Halloween costumes, traveling, and sampling craft brews.

I grew up in the beautiful teeny town of Garrettsville, OH where I spent my childhood Irish Step Dancing, playing softball, and working at my dad's hardware store. I did my undergrad at Youngstown State University and medical school at Northeast Ohio Medical University. My high school sweetheart and now husband, Matt, brought me to Dayton as he's a medical student at Wright State Boonshoft SOM.  In my free time, you can find me fly fishing the Mad River, knitting by the fireplace, or attempting to make something I saw on the Great British Baking Show. EM interests: teaching and palliative medicine.

Jennifer Zambales, M.D. — R1
Loma Linda University, School of Medicine

South Texas raised, southern California to Dayton transplanted, and thrilled to be part of such a stellar residency program. Besides emergency medicine, I love finding foods that make me dance in my seat, the smell of campfire under a blanket of stars, watching my plant babies grow (it'll be a few years before I'm sharing persimmon with y'all), house music, and live shows. My fiancé and I are trying to learn French for a future in global health, but we'll see how well practiced that will be here in Dayton, Ohio. My short term goal is to run into Dave Chappell at a grocery store or gas station, nod at each other in passing, and be on my way - knowing the stars aligned and brought me to Dayton for that very moment.
