To My Valued Patients,

After 30 fulfilling years of practicing Orthopaedic Surgery in Milwaukee, I am writing to share that I have retired.

This decision did not come easily, as caring for you—my patients—has been the greatest honor of my professional life. Over the past three decades, I have had the
privilege of helping individuals regain strength, mobility, and quality of life. Each surgery, consultation, and follow-up has deepened my appreciation for the trust you placed in me and the relationships we built together.

As I step away from the operating room and clinic, I do so with gratitude and confidence that you will continue to receive excellent care at Wisconsin Bone and Joint. I will be working closely with my practice partners and staff to ensure a smooth transition, and your medical records will remain securely on file for continuity of care.

One of the most rewarding aspects of my career has also been the opportunity to mentor and educate the next generation of Orthopaedic Surgeons. This included 22 Upper Extremity Fellows and over 60 Orthopaedic Residents. I’ve taken great pride in sharing knowledge and experience with these young physicians. Knowing that I’ve had a hand in shaping capable, compassionate surgeons who will continue to serve this community brings me great comfort and satisfaction as I step away from active practice. I am grateful for the support of our dedicated clinical team who made it possible for me to offer you the best care. I’m also deeply proud of the resilience, courage, and determination I witnessed from so many of you during your recovery and healing.

Please know that it has been a profound privilege to serve this community. Milwaukee has not just been where I practiced—it has been home.
Thank you for allowing me to be part of your Orthopaedic journey.

If you have any orthopaedic conditions that need to be addressed, Dr. Zeigler encourages you to call our offices and Dr. Ziegler’s care team will refer you to the appropriate partner.

With sincere appreciation,

Dean W. Ziegler, M.D.

Dr. Jacqueline Mlsna is a board-certified orthopedic surgeon specializing on sports medicine, fracture care and joint replacement.

“Patients deserve the personal attention of their physician who should partner with them in forming a personalized diagnosis and treatment plan. Many orthopedic surgeons in this community have abandoned the traditional doctor/patient relationship, choosing to provide only the most technical aspects of their patients’ care. Most of the evaluation, examination and consultation is provided by an assistant with considerably less training and experience. In this model of care, surgeons do not see their patients in the hospital after surgery, nor do they provide personal aftercare in the office. I believe, on the other hand, that the doctor/patient relationship is crucial to a patient’s care. In my view, personal interaction between a physician and patient provides the best opportunity for proper diagnosis and treatment, along with the best opportunity for a good outcome.

Every patient deserves and should expect nothing less.”

A Letter of Gratitude and Transition
Dear Patients, Colleagues, and Friends,
After much reflection, I am writing to share that I will be retiring from the practice of orthopaedic surgery. My last day will be
June 11, 2026.
This decision comes with deep gratitude and, admittedly, mixed emotions. Orthopaedics has been more than a career to me-it has
been a calling, a community, and a privilege that has shaped my life in ways I could never have imagined when I began this
journey.
I was fortunate to begin my education here in Milwaukee, attending Marquette University before earning my medical degree at
the Medical College of Wisconsin. I completed my internship and residency at MCW, where I also had the honor of serving as
Chief Resident. Those formative years instilled in me not only a love for orthopaedic surgery, but also the values of teamwork,
humility, and service–principles that have guided me ever since.
In 1987, I joined Orthopaedic Associates, and it has truly been my professional home. Over the years, I have been privileged to
practice alongside exceptional colleagues, and staff, who share a commitment to putting patients first. The 2015 merger with
Blount Orthopaedic Specialists was especially meaningful to me. I was fortunate enough to have met Dr. Blount as a resident, so I
was excited to become part of that legacy. More recently our merger with Wisconsin Bone & Joint, S.C. has continued that
tradition of growth, collaboration, and excellence in care.
One of the greatest joys of my career has been practicing alongside my son, who joined the group 13 years ago. To watch him
care for patients with skill, compassion, and integrity has been among my proudest experiences, both as a physician and as a
father.
To My Patients: thank you for placing your trust in me during some of the most vulnerable moments of your lives. It has been an
honor to care for you and your families. The relationships built over decades–often across generations–are what I will miss the
most.
To My Colleagues And Staff: you are the heart of this practice. Your dedication, kindness, and professionalism are what make it
such a special place to work. I am endlessly grateful for the teamwork, laughter, and support we have shared. You have made
even the most challenging days meaningful.
While I may be stepping away from the exam room, I leave with immense confidence in the future of this practice, and in the
people who will continue to provide outstanding care. I will miss the daily connections, the shared purpose, and the privilege of
serving this community more than words can fully express.
Thank you for allowing me to be a part of your lives and for making my career so fulfilling. It has truly been the honor of a
lifetime.
With sincere gratitude,
John Kroner, MD
