Michael Karczewski Dr. Michael B. Karczewski, D.D.S.

I am an alumnus of the Marquette University School of Dentistry and the graduate program in prosthodontics at Marquette. I feel so strongly that my time here shaped me so positively to become the dental professional I am today, as well as those years being some of the most enjoyable of my life. I continued as dental faculty right from my time as a resident continuously through to today, now approaching 30 years. I have never regretted the opportunity to help guide the residents through their educational experience since they give back to me as much or more than I have given them.


Charles PechousDr. Charles E. Pechous, D.D.S.

I have been a part of the Marquette School of Dentistry, first as a student, then as a resident and now a part of the faculty. I enjoy teaching residents and working in my private practice. It’s hard to have any free time, but when I do I enjoy hunting and fishing, mostly with my kids.

I have always been interested in Prosthodontics education. As a past Prosthodontics program director and currently faculty at the Marquette School of Dentistry, I have greatly enjoyed sharing ideas and techniques with highly motivated residents.



Les TimmDr. Leslee Timm, D.D.S.

Leslee (Les) Timm is a unique dentist. His training and love for dentistry began at Marquette School of Dentistry in 1998. He then had an opportunity to serve our nations veterans while completing a three-year Prosthodontic residency with the VAMC in Portland, Oregon. Les joined a select few accepted to UCLA’s Fellowship in Oral and Maxillofacial prosthetics in 2005. While at UCLA Les had the opportunity to provide prosthetic rehabilitation for patient suffering facial and oral deformity under the mentorship Dr. John Beumer, III. In 2007 Dr. Timm became Prosthodontic division head of Gunderson Health System’s Department of Dental Specialties. His strong desire for education and the science of surgery led Dr. Timm to complete his surgical training with Gundersen Health System in 2015. Les is now proud to say that he is one of a very few dentists to complete Prosthodontic and Oral Surgery residencies and is now the only one of that group who is board certified in both fields. Dr. Timm now owns a private practice in Lacrosse, Wisconsin limited to Oral & Maxillofacial Surgery and Prosthetics.

I am affiliated with Children's and Froedtert hospitals for cleft palate and head and neck cancer patients. I enjoy taking the prosthodontic residents with me for the rotation and to discuss treatment plans for these types of patients.



Kenneth J. Waliszewski Dr. Kenneth J. Waliszewski, D.D.S., M.S.

From day one in dental school, prosthetic dentistry has been my focus. I enjoyed and did well in my pre-clinical prosthodontic courses.  This led a faculty member to suggest me to an area dentist whose practice was devoted to rehabilitation cases. For almost three years, I worked evenings and weekends as a dental technician for that dentist.  After graduating with my D.D.S. in 1971, Marquette accepted me into its prosthodontic program. The three-year program passed rapidly as I was a graduate student by day and a dentist by night in the office I started in as a lab technician. 

These were Vietnam War years, and I joined the U.S. Navy to control my draft status. In exchange for not being drafted, I was obligated to go active duty after completing school. The spring of 1974 was a significant time for me. I finished the prosthodontic program, completed a master’s thesis, got married and reported for active duty with the Navy. The Navy recognized my training and assigned me to the Balboa Navy Hospital in San Diego, where I practiced as a prosthodontist until 1976. I was treated exceptionally well by the Navy. At the hospital, I found myself immediately and totally engaged with fixed and removable cases. My Marquette training and fellow Navy prosthodontists helped me survive the schedule. The two greatest memories I have of the Navy hospital are caring for Vietnam prisoners of war and my first son’s birth at that hospital.

After my Navy tour, I returned home to join Marquette’s part-time faculty and start a practice limited to prosthodontics. In 1976, Marquette gave to me the opportunity to direct the Pre-clinical Fixed Prosthodontics course. I held that position for the next 26 years. I continue to enjoy participation on Marquette’s part-time faculty as a clinical instructor in graduate prosthodontics. After 42 years of clinical practice, I retired from the office in 2013.

Next to my wife and family, my greatest love in life is reading. Reading history and the classics is a continuing joy and adventure. Reading art history is invigorating and interesting, which reading papers and journals keeps me engaged with the world and feeling young.


Michael P. WaliszewskiDr. Michael P. Waliszewski, D.D.S., M.S.D.

After graduating from the Marquette University School of Dentistry with his D.D.S. in 2002, I was named the first recipient of the David H. Wands fellowship in prosthodontics at the University of Washington. I received my certificate and M.S.D. from the UW Graduate Prosthodontic program in 2005.

After graduation, I joined the full-time School of Dentistry prosthodontic faculty at Marquette. Since late 2009, I have continued to teach part time at Marquette while working in a private practice limited to prosthodontics in Brookfield, Wis. Significant peer-reviewed publications include articles in the JPD, J Pros, PPAD and JERD. Lecturing mainly locally, my most popular topics include denture esthetics, complete denture therapy, modern removable partial denture philosophy, implant platform selection, and treatment planning debilitated dentitions. I am active in the ACP, OKU, UW Graduate Prosthodontic Alumni association, and dental forum of Milwaukee. Dentistry is my hobby, and I also have done rotisserie (the original fantasy) baseball since 1994. I live in New Berlin, six blocks from where I grew up. My wife Deanne is from Whidbey Island, Wash., where we like to visit when we can.
