University of Washington Professor Accused of Child Sex Abuse and Other Sexual Misconduct

Why This Site Exists

As detailed in sworn testimony contained in public documents, this website compiles allegations of child sex abuse, sexual misconduct, and sexual harassment relating to Dr. Michael Piepkorn. This website is intended to bring attention to sexual misconduct, harassment, and sex abuse perpetrated by Dr. Michael Piepkorn, a University of Washington Medicine clinical faculty member and Dermatopathology Northwest pathologist. It is curated by individuals who were directly impacted by Dr. Piepkorn's abuse, including victims and eyewitnesses. The site serves as a public archive of firsthand accounts of abuse contained in sworn statements and court declarations. Sexual misconduct thrives in silence. This website provides survivors and witnesses a public platform to ensure their voices are heard—not buried, ignored, or erased. The courage of those who have come forward deserves acknowledgment and action. This website aims to document and preserve testimony, legal declarations, and other materials related to serious allegations of child sexual abuse and other forms of sexual misconduct and sex abuse involving Dr. Piepkorn.

As a faculty member at a publicly funded university, Dr. Piepkorn was supported by taxpayer dollars and entrusted with power and responsibility. With that comes a higher standard of ethical conduct and transparency. Those in positions of public trust must be held accountable when that trust is broken. This site stands as a living record—a challenge to the institutions that enabled misconduct, a call for justice and reform, and a commitment to ensuring that what happened to these victims is neither forgotten nor repeated. This website is entirely non-commercial, and none of the victims or contributors receive any financial benefit from its existence or visibility. It is a labor of truth and advocacy, not profit. This website exists out of a shared commitment to calling attention to prior abuse perpetuated by Dr. Piepkorn, protecting others, and preventing future harm. This website is purely for truth-telling and advocacy for change, a victim’s right protected by the First Amendment.

Sworn Testimony

Eyewitness Recounts Dr. Piepkorn's Horrific Sexual Abuse

“What my children went through was unspeakable. Words do not describe the pain my children and I have endured. Dr. Piepkorn’s family robbed my children of their innocence. They tortured my children in ways that are absolutely horrific and unspeakable. I cannot fathom how someone would do such despicable things to children, let alone their own biological children.”

“Over the years, I have personally witnessed Dr. Piepkorn engage in sexual misconduct involving several young women. Dr. Piepkorn is a sexual predator. Some of that sexual misconduct happened at events sponsored or hosted by Dermatopathology Northwest.”

“The things that I have come to witness and know about Dr. Piepkorn and his sexual misconduct are downright despicable and horrific.”

“I felt that I had the obligation to speak up about Dr. Piepkorn’s sexual misconduct that I have personally witnessed because no one should have to go through the sex abuse Dr. Piepkorn put them through.”

“Dr. Piepkorn has hired an army of attorneys at powerful law firms like [Marty McLean and Jessica Thompson of] Hagens Berman and [Thomas Hansen of] Oseran Hahn to help cover-up his sexual misconduct and bully his victims into silence.”

Victims Urge UW to Investigate Dr. Piepkorn's Sex Abuse

“My primary purpose in writing to you today is to voice my concern for Dr. Piepkorn’s alarming conduct, including giving a voice for the many victims of Dr. Piepkorn. Dr. Piepkorn’s bizarre and deeply disturbing misconduct has adversely impacted a number of people and I aim to give a voice to all those who were wronged by Dr. Piepkorn. For many years, Dr. Piepkorn has continued to abuse and torment those around him, whether it is consistently keeping neighbors under surveillance, sexually abusing certain individuals, or helping both of his children escape culpability for child sex abuse crimes.”
“But above all, I write on behalf of the then 7-year old and 2-year old victims that Dr. Piepkorn did nothing to protect against. Dr. Piepkorn’s complacency, coupled with his own bizarre, over-the-top behavior, is a significant cause for concern that I believe the UW leadership should investigate. For far too long, Dr. Piepkorn has used his position to misappropriate the public trust and engaged in serious misconduct that warrants further investigation.”
“The University should put an end to Dr. Piepkorn’s misconduct and I believe it should investigate its relationship with Dr. Piepkorn. By conducting an investigation into the University’s relationship with Dr. Piepkorn, the University would be sending a signal that it stands in solidarity with victims of child sex abuse. By continuing to standby Dr. Piepkorn, the University would further a culture of institutional indifference that has enabled Dr. Piepkorn to continue to abuse those around him for years on end.”
“The University of Washington should be ashamed of itself for continuing to support and foster a culture of predatory sexual behavior amongst its staff, including Dr. Piepkorn. In general, medical doctors are held to a high standard in society. When child sex abuse allegations against doctors surface, people are generally quick to dismiss them because of the stature medical doctors hold in our society. But it is exactly that type of institutional dismissiveness that cultivates sexual predators like Dr. Piepkorn. How long do we have to wait until Dr. Piepkorn becomes the new Larry Nassar? Remember, Michigan State University leaders dismissed child sex abuse allegationsagainst then Dr. Larry Nassar because they believed that the child sex abuse allegations against then-Dr. Nassar to be “unsubstantiated.” Let’s not make the same mistake with Dr. Piepkorn.”

Dr. Piepkorn Used His Position at UW to Hide Sexual Misconduct

Dr. Piepkorn is a dermatologist and pathologist with Dermatopathology Northwest in Bellevue, WA. To rebut the allegation that Dr. Piepkorn had an issue with indecent exposure, which included Dr. Piepkorn exposing himself at a medical conference in New Orleans, Dr. Piepkorn had a clinical instructor in the Division of Dermatology at the UW School of Medicine write a letter on UW School of Medicine letterhead “certifying” that she “did not state that Dr. Michael Piepkorn publicly exposed himself”:

Dr. Asgari then stated that she was “truly sorry for any misunderstanding that this joke, which was meant as a lighthearted roast, may have caused.” Id.
Regardless of whether Dr. Asgari actually said if Dr. Piepkorn publicly exposed himself, the fact remains that it is inappropriate for Dr. Piepkorn to be using the name of UW School of Medicine and taxpayer resources to rebut allegations of indecent exposure. By using UW School of Medicine’s and Division of Dermatology’s letterhead to rebut allegations of indecent exposure, Dr. Piepkorn is indirectly leveraging the name of the UW School of Medicine to combat allegations that Dr. Piepkorn publicly exposed himself. In doing so, Dr. Piepkorn lowers the prestige of the UW School of Medicine.
The fact that Dr. Piepkorn continues to use his position and his association with the UW School of Medicine and the Division of Dermatology to combat allegations of sexual misconduct (indecent exposure) is deeply disturbing. Taxpayer resources should not be used to rebut allegations that Dr. Piepkorn exposed himself at a medical conference—certainly not in a private dispute involving Dr. Piepkorn and Shelley Desmond.

Dr. Piepkorn's Own Family Details Dr. Piepkorn's Sex Abuse and Harassing Behavior

“If a restraining order is entered, I would be comforted to know that Mike would be restrained from giving any type of material like this directly, indirectly or inadvertently to our children. He should be restrained from having any pornographic material in his home and he should be required to install filters on his computer to restrict internet access to pornographic material.”
“The information I have provided Dr. Olson includes my statements of my personal knowledge, Mike's admissions to me and other tangible evidence of the following:
- Allegations of indecent exposure in New Orleans during a medical conference
- Instances of Mike's hiring prostitutes from a strip club to meet him at a Seattle Spa known as Tubbs
- Allegations in sworn declarations in Adams v. Desmond, King County Case No. 98-2-28905-8 alleging that Mike was looking into the windows of our neighbor’s homes (peeping tom) and about the nature of Mike’s anger.
- King County Sherriff’s Officer Eric Soderstrom, visit about a neighbor who alleged that Mike threatened to kill her."

Dr. Piepkorn's Neighbors Detail His Sexual Harassment and More Harassing Behavior

Mary Anne Adams, testified about the constant harassment she and her husband endured at the hands of Dr. Piepkorn, including how Dr. Piepkorn kept them under surveillance for months on end and how Dr. Piepkorn subjected Mrs. Adams to unwanted sexual harassment, and why she needed to obtain a fence to keep Dr. Piepkorn away:
“I think it is important for the court to understand why this is such an issue. We want a fence because Mr. Piepkorn has continually subjected myself and my husband to numerous forms of harassment. He has kept our house under video surveillance for months at a time. When my husband is not around, Mr. Piepkorn has come up to me on my property and insulted me in the most personal and demeaning way, making creepy sexual references about my looks, my husband, etc. He makes continual hand gestures to us. On a number of occasions, he has attempted to provoke physical combat with my husband. We have caught him peeping into our windows and into the windows of two other neighbors. We are not the only ones Mr. Piepkorn does this to; our neighbors the Trujillos have seen it also. Despite my requests to him, Mr. Piepkorn repeatedly mowed our lawn. He used to put his lawn furniture on our property and ostentatiously sit down to enjoy it. When we had house guests, he would come over uninvited, sit down, and introduce himself. He continually intruded on our privacy. I feel I need a fence for security.”

Dr. Piepkorn's Neighbors Recount Dr. Piepkorn's Stalking and Peeping Tom

Cindy Trujillo, another one of Piepkorn’s neighbors, stated that she too witnessed Piepkorn’s disconcerting behavior towards others:
“We know that both of our fences are also preventing our common neighbor, Mr. Piepkorn, from wandering onto our properties both during the day and at night with his flashlight which has been rather disconcerting.”

Another neighbor, Joe Trujillo, who was also a reserve police officer, previously testified that he too witnessed Piepkorn’s disconcerting behavior on several occasions:
“I wish to inform the court concerning my direct observations and encounters with Mr. Piepkorn, and his conduct towards the Adams which I have observed.”
Before the Adams put up their fence, I saw Mr. Piepkorn in the Adams’ backyard on a number of occasions, usually in the middle of the night, shining a flashlight and looking into windows. On several occasions, I have seen him doing the same thing at my house. I have had to explicitly warn him not to come onto my property again.
We decided to put up a new fence along our lot line. Mr. Piepkorn harassed my employees who were installing the fence, and yelled at me in a manner that was truly shocking. He twice challenged me to fist fights because of my fence.”
