Jetta Holloway-Jankowski D.D.S

JettaI was born and raised in Beloit, and have always enjoyed the rural lifestyle and practicing with my dad, Dr. Milt. I am a 2003 graduate of Beloit Jr/Sr High School. I then attended college at Creighton University in Omaha, Nebraska, where my interest in Chemistry resulted in an invitation to attend Creighton University School of Dentistry through the Early Acceptance Program. I was elected class president all four years, only declining my sophomore year to focus on my wedding to Tim Jankowski, a classmate of mine in dental school. During my Junior year, I was inducted into Omicron Delta Kappa, a national honor society, and at the end of my Senior year, I was also selected for the Eleanor J. Bushee Memorial Award from the American Association of Women Dentists for Academic Excellence and Outstanding Leadership.  With Dr. Milt, I maintain my clinical excellence through countless hours of continuing education in cosmetic and general dentistry.   I continue to work with nationally known instructors on the latest techniques and skills. I am active member in the American Dental Association, The Kansas Dental Association, The Academy of General Dentists, and the American Association of Women Dentists.  Tim and I are both 2010 graduates of Creighton Dental School. I enjoy spending time with Tim, Graham (our son), Amelia (our daughter) and our two dogs, family and friends as well as cooking, working out, home improvement projects, snow skiing and water skiing.  I am currently scheduling patients and welcome all to our practice. 


Tim Jankowski  D.D.S.

I was born and raised in Omaha, NE where I attended high school at Creighton Preparatory School, graduating in 2002, and Undergraduate at the University of Nebraska at Omaha. I graduated from UNO in December 2005 with a Bachelor’s Degree in Biotechnology before beginning dental school at Creighton University in the fall of 2006.  While attending Creighton Dental School I received a scholarship from the United States Air Force.  After graduating in May 2010, I attended Commissioned Officer Training School at Maxwell AFB in Alabama, and was then stationed at Offutt AFB in Bellevue, NE.  During my year at Offutt, I completed a one year Advanced Education in General Dentistry residency program where I learned many new dental procedures including IV Sedation and removal of impacted wisdom teeth.  After completing my residency, I was moved to McConnell AFB in Wichita, KS where I worked in a small Air Force Dental clinic with 5 other dentists to care for the dental needs of the active duty military population on base.  I completed my active duty service in July 2014 and am glad to now be living and working full time in Beloit.  I still serve as a reserve Dentist at McConnell AFB one weekend per month and was appointed as Dental Flight Commander.  I enjoy spending time with Jetta, Graham (our son), Amelia (our daughter) and our two dogs, family and friends as well as hunting, military history, aviation and home improvement projects.  I look forward to meeting and getting to know all of the patients at Dental Designs, both new and established.
