Why You Should Choose a Fellowship Trained Mohs Surgeon
Mohs Skin Cancer Surgery
Mohs micrographic surgery set a new standard in skin cancer treatment. Established by Dr. Frederic Mohs, Mohs surgery is widely accepted as the most effective treatment for most types of skin cancer. An increasing number of physicians are performing this surgery, and it's important to choose doctors who have the best training and surgical experience.
Our Mohs Surgeons
Starting his practice more than 30 years ago, Dr. Patrick J. Lillis was a pioneer in Mohs skin cancer surgery, one of the first to be trained in Colorado and the Rocky Mountain States. There are several doctors who perform skin cancer surgery at Lake Loveland Dermatology. Patrick J. Lillis and Matthew J. Mahlberg are fellowship-trained doctors who perform Mohs surgery and Dr. Joseph V. Lillis is a board certified dermatologist whose expertise includes skin cancer surveillance and skin cancer surgery.
Mohs surgeons who have achieved the highest degree of Mohs surgery qualification are fellowship trained Mohs surgeons. Dr. Matthew J. Mahlberg and Dr. Patrick J. Lillis are both fellowship trained, which means that they have completed an American College of Mohs Surgery (ACMS) approved fellowship. For you, this means peace of mind, knowing that you will receive superior quality and competency, as well as an optimal outcome.
ACMS - Committed to Superior Care
The ACMS was established by Dr. Frederic Mohs himself, and its fellowship training program is generally acknowledged as the benchmark in Mohs surgery training. Through an extensive application and interview process, only the most qualified physicians are selected by ACMS to participate in a fellowship program. Participants must undergo a rigorous 1 to 2 year training program subsequent to completing a residency in dermatology.
During fellowship training, Dr. Patrick J. Lillis and Dr. Matthew J. Mahlberg each studied and trained under the guidance of veteran Mohs College surgeons who have demonstrated expertise in Mohs surgery. A cornerstone of the ACMS fellowship training program is cultivating experience and judgment in each graduate. Since skin cancer occurs in a diversity of forms, degrees and locations, the program is set up to be thorough and stringent.
The following requirements must be met in completing an ACMS fellowship:
- Participatiom in a minimum of 500 Mohs surgery cases
- Learning to accurately interpret slides of tissue samples removed during Mohs surgery
- Performing a vast array of reconstructions, ranging from the simplest to the most complex, multi-step repairs
An ACMS graduate, Dr. Matthew J. Mahlberg gained an uncommon level of exposure, including everything from challenging tumor locations to rare tumor pathology and complex wound reconstruction.
Rest assured that Dr. Matthew J. Mahlberg and Dr. Patrick J. Lillis have the training and experience to achieve the best outcome from your skin cancer treatment.
