Warthan Dermatology Center

Your skin is your largest—and one of your most important—organs. Why trust it to anyone but the skin care specialists and board certified Top Docs at Warthan Dermatology Center? Offering complete skin care for patients of all ages, from infancy through the senior years, Dr. Mandy Warthan, Dr. Robert Marinaro, and the team at Warthan Dermatology strive to go above and beyond, providing personalized, high-quality skin care with a human touch.

Patients Love Warthan Dermatology Center

When Steve, Shay, and Tiffany were asked to share their Warthan Dermatology experiences with Living Magazine, they happily obliged.

“Dr. Warthan impressed me at my first appointment,” says Tiffany, a longtime patient. “The office is comfortable—not sterile like you might imagine a doctor’s office to be—and the staff and doctors are friendly and welcoming. They ask about my family and kids and provide care that comes from the heart.”

Over the years, Tiffany has had aesthetic treatments such as chemical peels and microdermabrasion performed at Warthan Dermatology, as well as medical treatments, including skin cancer surgery. “My children have seen Dr. Warthan and I referred my mother to her for skin cancer surgery. I highly recommend Dr. Warthan and her team.”

Steve says meeting Dr. Robert Marinaro was like meeting an old friend. “Dr. Marinaro is remarkable! He is knowledgeable and professional, and I enjoy his down-to-earth personality and good-natured sense of humor. He totally gets the humanity part about being a doctor. It makes you want to return to see him even if there’s nothing wrong with you! That’s how special he is.”

Shay “fell in love with Dr. Warthan and the whole staff” during her first appointment. Eight years later, she still feels the same way. “I go to Warthan Dermatology for medical and aesthetic procedures. They do both very well and I couldn’t be more pleased.” She adds, “Patients are treated kindly. You’re remembered not only by name, something you can look up on a chart. They remember little details about you and make a personal connection with you.”

“We strive to build a close relationship with our patients. We have many families where we see the children for acne or warts and the parents and even grandparents for skin cancer checks and more,”
Dr. Warthan says. She also praises her staff. “Everyone goes the extra mile to help our patients feel well cared for. Several on our team have been with me since I opened the practice eight years ago and have grown with us.”

Complete Skin Care

Warthan Dermatology offers a full array of medical and surgical dermatologic services, including skin cancer screening, diagnosis, and surgery. The center is also the place to go for innovative, results-oriented aesthetic skin care services. Top-of-the-line skin treatments, as well as 15 different laser procedures, are provided by experienced and licensed aestheticians.

“We offer the best injectible cosmetic services like Botox, Juvéderm, and Restylane all performed by board certified dermatologists,” Dr. Warthan says.

Dr. Marinaro is known for his skill in creating beautiful, natural-looking results with injectables. “Botox and dermal fillers aren’t one and done cookie-cutter treatments. Every patient can react differently and not everyone uses their facial muscles the same way. I follow up with my patients after treatment and strive for perfection each time,” he says.

More About Warthan Dermatology’s Top Docs

It takes years of postdoctoral education to become a dermatologist. Drs. Warthan and Marinaro have taken it a step further. Dr. Warthan is dual-board certified in dermatology and dermatopathology, a demanding discipline that focuses on the microscopic diagnosis of skin cancers, moles, and other skin diseases. Fewer than three percent of dermatologists are also dermatopathologists.

Dr. Marinaro is board certified in dermatology and completed two years of residency in internal medicine, giving him a unique perspective when diagnosing and treating complex dermatologic conditions. Taking a holistic approach, he often spots potential underlying health conditions and refers patients to other medical specialists for diagnosis and care.

Both doctors attend numerous medical conferences and complete continuing education annually to stay on the cutting-edge in their specialty.
