Honestly, if you've ever looked into Mohs surgery or specialized dermatology in the Midwest, you’ve likely stumbled across the name Dr. Marcy L. Street, MD. She isn’t just another doctor with a lab coat and a clipboard. She’s a pioneer. Specifically, she was the first African American woman ever to become a fellowship-trained Mohs surgeon. That's a massive deal. Mohs micrographic surgery is basically the gold standard for treating skin cancer, and breaking into that elite circle back when she did required more than just smarts. It required a level of grit most people can't fathom.
She’s the founder of Doctor’s Approach Dermatology in Okemos, Michigan. People travel from all over to see her. Why? Because she understands skin in a way that goes beyond surface-level aesthetics. She’s dealing with the intersection of oncology, surgery, and pathology.
What Dr. Marcy L. Street, MD Actually Does Differently
Most people think a dermatologist just looks at rashes or prescribes acne cream. That's not Dr. Street. While she handles general derm, her real wheelhouse is the surgical removal of skin cancer.
Mohs surgery is incredibly meticulous. The surgeon acts as the doctor, the pathologist, and the reconstructive surgeon all at once. Imagine removing a layer of skin, looking at it under a microscope right there in the office, and then going back for more only if the margins aren't clear. It saves as much healthy tissue as possible. It's an art form, really. Dr. Marcy L. Street, MD has spent decades perfecting this. She studied at Mayo Clinic. That’s the big leagues. When you train at Mayo, you’re learning from the best of the best, and she brought that high-level intensity back to Michigan.
She doesn't just cut and sew. She looks at the patient as a whole person. It’s kinda rare to find someone who has that high-level academic background but still talks to you like a human being. She’s focused on "Total Skin Health," a philosophy she’s championed for years.
The Mayo Clinic Foundation
Her time at the Mayo Clinic in Rochester, Minnesota, is a cornerstone of her career. It’s where she completed her residency and her fellowship in Mohs Micrographic Surgery and Dermatologic Surgery. This isn't just a line on a resume. The Mohs fellowship is notoriously rigorous. You’re doing thousands of cases. You’re learning how to read slides with extreme precision. If you miss one cancerous cell, the whole thing fails. Dr. Street didn't miss.
She has this deep-seated belief that everyone deserves elite care, regardless of their background. Being the first Black woman in this specific sub-specialty meant she had to be better than everyone else. She was.
Beyond the Scalpel: Products and Innovation
Dr. Street realized pretty early on that she couldn't be in the exam room with everyone 24/7. So, she developed her own line of products. It’s called Doctor's Approach. Most celebrity doctor brands are just white-labeled generic stuff with a fancy sticker. Her approach was different. She wanted to bridge the gap between "medical grade" and "over-the-counter."

She focused on things like pH balance and specific ingredients that actually penetrate the skin barrier. If you've ever dealt with hyperpigmentation or scarring after a procedure, you know how hard it is to find stuff that works. She leaned into her clinical experience to formulate products that support the skin’s natural healing process.
Why Michigan?
A lot of people ask why a Mayo-trained surgeon would set up shop in Okemos, Michigan, instead of Beverly Hills or New York. It’s simple. There was a desperate need for high-level dermatologic surgery in the Greater Lansing area. She built a state-of-the-art facility that includes an on-site pathology lab. This is crucial. It means patients don't have to wait a week for results. You get your surgery, the lab checks the margins, and you're done.
It’s about efficiency and patient anxiety. Waiting for a phone call to find out if your cancer is gone is agonizing. She fixed that for her community.
Addressing the Myths About Skin Cancer
There’s this weird, persistent myth that people with darker skin don't get skin cancer. Dr. Marcy L. Street, MD has spent a large portion of her career debunking this. It’s dangerous. While melanin does provide some natural protection, it’s not a suit of armor. In fact, skin cancer in people of color is often diagnosed at a later stage, which makes it much harder to treat.
She’s a vocal advocate for early detection across all skin types. She often points out that acral lentiginous melanoma—the kind that killed Bob Marley—shows up on the palms, soles, and under the nails. People miss it because they aren't looking there. Dr. Street looks there.
The Science of the "Clear Margin"
In Mohs surgery, the goal is a 100% clear margin.
- The visible tumor is removed.
- A thin layer of tissue around the site is taken.
- That layer is mapped, frozen, and stained.
- The surgeon (Dr. Street) examines the edges under a microscope.
- If cancer remains at any edge, another layer is taken only in that specific spot.
This process repeats until no cancer is left. It has the highest cure rate for most basal cell and squamous cell carcinomas. It’s why she’s so respected. The precision is unmatched.

Leading the Way in a Male-Dominated Field
Let’s be real for a second. Surgery, historically, has been a boys' club. Dermatology is becoming more diverse, but the surgical side—especially Mohs—took longer to catch up. Dr. Street didn't just walk through the door; she kicked it down. She’s served as a leader in the American Society for Mohs Surgery and the American Academy of Dermatology.
Her presence in these spaces matters. It changes the conversation about who gets to be an expert. It changes how clinical trials are designed and how skin diseases are studied in different populations.
The Doctor’s Approach Philosophy
What does "Total Skin Health" actually mean? It’s not a marketing slogan. For Dr. Street, it’s about the intersection of lifestyle, nutrition, and medical intervention. You can’t just fix a skin issue with a pill if the environment or the routine is broken.
She often talks about the "internal" factors of skin health. Stress, sleep, and hydration aren't just "lifestyle" tips; they are biological imperatives for skin repair. When she consults with a patient, she’s looking at the whole picture. She wants to know why the skin is reacting the way it is, not just how to cover it up.
Educational Impact
She isn't just a practitioner; she's a teacher. She mentors medical students and residents. She’s published in numerous medical journals. If you look up her name in academic databases, you'll see her contributions to the understanding of skin cancer and surgical techniques. She’s ensuring that the next generation of dermatologists has a higher bar to meet.
What You Should Do Next
If you’re worried about a spot on your skin, or if you’ve been told you need Mohs surgery, you need to be proactive. Here are the actual steps you should take based on the standards set by experts like Dr. Street:
Check the "Hidden" Spots
Don't just look at your arms and face. Check between your toes, your scalp, and the soles of your feet. Use a hand mirror or have a partner help. Look for anything that is changing, itching, or bleeding.

Ask About Fellowship Training
If you need skin cancer surgery, ask your doctor if they are fellowship-trained in Mohs. There is a difference between "doing Mohs" and being a fellowship-trained Mohs surgeon. The latter involves an extra year or two of incredibly intense, specialized training.
Protect Your Barrier
Stop over-exfoliating. A lot of the skin issues Dr. Street sees are actually caused by people destroying their skin's natural moisture barrier with too many harsh chemicals. Keep it simple. Gentle cleanser, moisturizer, and SPF 30 or higher every single day. Even if it's cloudy. Even if you're inside.
Understand Your Risk
Know your family history. If a direct relative had melanoma, your risk is significantly higher. This isn't about scaring yourself; it's about being informed so you can catch things early.
Dr. Marcy L. Street, MD has spent her career proving that excellence isn't just about what you know, it's about how you apply it to help people. She’s a pioneer for a reason. Her work in Okemos and her influence on the national stage have fundamentally changed the way we think about dermatologic surgery. Whether she’s at the microscope or in a board meeting, she’s pushing the boundaries of what’s possible for skin health.
If you're in the Midwest, having access to her level of expertise is a massive advantage. If you're not, her principles of "Total Skin Health" and the importance of Mohs surgery are still things you can advocate for in your own care. Skin cancer is treatable, but you have to be vigilant. You have to take it as seriously as she does.
To ensure your skin remains healthy, start by scheduling a full-body skin exam with a board-certified dermatologist who specializes in your specific concerns. Ensure that any surgical recommendations involve a clear discussion about margins and reconstruction options. Finally, audit your current skincare routine to eliminate any products that cause chronic irritation, which can lead to long-term inflammation and cellular damage.
