 Zachry L. Waterson, DO, Family Medicine Residency Director & Director of Osteopathic Medical Education





Zachry L. Waterson, D.O., F.A.A.F.P., Family Medicine Residency Director & Director of Osteopathic Medical Education

Hi and welcome to FWMEP.  I am a native Hoosier and grew up in Syracuse, Indiana on Lake Wawasee.  I love northern Indiana and the lake living it has to offer.  I did not venture too far off for my undergraduate training as I attended Manchester College in North Manchester, Indiana where I received my Bachelor’s Degree in Biochemistry.  I graduated Summa Cum Laude in 1999 from the University of Health Sciences College of Osteopathic Medicine in Kansas City, Missouri where I received my medical degree.  I moved back to Indiana and Fort Wayne for my residency training which I completed here at the Fort Wayne Medical Education Program. I completed residency training in 2002, serving as Co-Chief Resident during my 3rd year.

Finding Fort Wayne a great place to practice medicine and raise a family, I joined a private practice here in Fort Wayne. I joined the faculty of FWMEP in 2003, as the Director of Osteopathic Medical Education. In 2010, I left my private practice in order to take on a full-time role at FWMEP as an Associate Program Director.  During my time as Associate PD, I completed an Academic fellowship for Program Director Development.  In March of 2013, I was promoted to the role of Program Director. In 2013, I also received my degree of Fellow of the American Academy of Family Physicians.

My clinical interests are in internal medicine, obstetrics, and pediatrics. I have two beautiful daughters, Sydney and Riley, and I thoroughly love being a dad.  My fiancé, Pam, is a wonderful woman and is certainly my better half…Ha Ha…and would not know what to do without her, but don’t tell her that.  It should be known that I am an avid waterfowl hunter and fisherman.  I also enjoy golf and most watersport activities.  When I am not working, you will likely find me in the duck blind or at my lake home enjoying the outdoors with my friends and family.


 Aaron Coray, D.O.


Aaron Coray, DO, Associate Program Director

 I was born and raised in the small town of Mona, Utah.  At the age of 19, I went on a two year service mission to Brazil.  After receiving a B.S. degree in Biology at Utah Valley University, I attended Edward Via Virginia College of Osteopathic Medicine in Blacksburg, Virginia.  There I had an opportunity to do a medical mission to the Dominican Republic.  During residency at Fort Wayne Medical Education Program, I received the Patient Care Award.  After I completed residency in June of 2010, I stayed on as one of the faculty.  I was originally attracted to Family Medicine because of the wide variety of patients and pathology.  My clinical interests include: osteopathic manipulation, pediatrics, obstetrics, ultrasound, procedures, and emergency medicine.

I love to spend my free time with my wife, Kristina, and four beautiful, red-headed kids, Eli, Nathan, Paige, and Miles.  I also enjoy basketball, hiking, reading, exploring, and running half-marathons.

 Amy Dawson, MD, Associate Director


Amy Dawson, MD, Associate Program Director

I am originally from Idaho and received my undergraduate degree in French with an Anthropology minor from Wellesley College in Massachusetts.  After earning my medical degree from The Ohio State University, I trained in family medicine at the Fort Wayne Medical Education Program, graduating in 2000.  I then spent 3 years in private practice at Brooklyn Medical Associates, hoping to be able to leave for medical missionary work at the end of that time.  Instead, I ended up as the Medical Director of the Matthew 25 Health and Dental Clinic for four and a half years.  Finally, my family and I were ready to participate in mission work overseas and had the privilege of serving in Quito, Ecuador for almost four years.  In July of 2012, we moved back to Indiana and I joined the faculty of the Fort Wayne Medical Education Program as medical director of our Family Medicine Clinic, training new family medicine doctors to provide great healthcare now and in the future.




Gregory Eigner, MD, Associate Program Director

I received my degree in Systems Design Engineering from the University of Waterloo and my M.D. Degree from the University of Western Ontario. Following residency in Family Medicine at Victoria Hospital in London, Ontario, I entered private practice and provided the full spectrum of patient care there for seven years. This was followed by practice with a large multi-specialty group in Minneapolis, Minnesota, for another six years, where I served as a lead physician and site medical director. In addition to patient care, I was involved with organizing and opening a new clinic, implementing an electronic medical record system, redesigning office workflows, and facilitating clinical care improvement initiatives. I joined the Fort Wayne Medical Education Program in 2003. My interests include chronic pain management, health care quality, and process improvement. My wife Marianne and I have found Fort Wayne to be a great place to live and raise our two sons. I enjoy many sports, including golf and biking with my family as well as competitive curling, when possible.

I found the Fort Wayne area to be a great place to live and practice medicine and after graduation, I joined a Family Medicine group in Roanoke, a small suburb south of Fort Wayne.

After being in private practice for 11 years, I returned to the Fort Wayne Medical Education Program in 2010 as a full time faculty member. My clinical interests are obstetrics and preventative medicine. I very much enjoy teaching and interacting with the residents.

Catherine Gilreath, DO, Associate Program Director

I was raised in the small town of Antwerp, Ohio.  My family and I would frequently visit Fort Wayne since it was only 40 minutes from our home.  I received my Bachelor of Science in Zoology from Miami University (Love and Honor!) in Oxford, Ohio, in 2006.  At that point, I decided I needed out of Ohio and attended New York College of Osteopathic Medicine in Old Westbury, New York, for medical school.  I then returned to Fort Wayne for residency and graduated from Fort Wayne Medical Education Program in 2013 after being a co-curricular chief for two years and receiving special training in concussion management.  I practiced for two years in my home county before returning to Fort Wayne to become a full-time faculty member of the program.  I currently practice the full scope of family medicine, including obstetrics, and have additional training in osteopathic manipulation including cranial techniques. 

I have a wonderful husband who has introduced me to lake life and a son who is on the go all the time.  In our free time, we love to travel and spend time with friends and family.  We also spend a lot of time at the zoo! 













Brian Henriksen, PhD, Director of Research and Scholarly Activity

I was raised in an Air Force family and had the opportunity to live all over the country and abroad.  My interest in science took off at a young age and I’ve been at it ever since!  I earned a PhD in medicinal chemistry and molecular pharmacology from Purdue University. Subsequently my post-doctoral fellowship at The Scripps Research Institute focused on green chemistry using amino acid derivatives as bio-catalysts. 

After a short stint in the biotech industry I served as a faculty member in two pharmacy programs.  My teaching covered medicinal chemistry and the foundational sciences behind small molecule therapeutics and their clinical outcomes.  Over time my research interests shifted from bench top to bedside with notable community efforts.  In collaboration with clinical faculty, grant funded diabetes education support, oncology supportive care, and electronic nicotine delivery system education programs were established.   My strong ties to community service led to the grant funded creation of a vocational job skills program for underserved youth where the students learned blacksmithing.  Each session at the forge set up like a science lab to build job and academic skill sets. 

My wife and I have identical twin boys, Torin and Fenris, with family roots in Indiana and Wisconsin.

Ashraf H. Hanna, MD, Assistant Director
