Dr. Monica Scheel

Dr. Scheel is a Board Certified Dermatologist with over 20 years of experience in skin conditions and treatments for the skin, hair, and nails. She began her skin wellness center in Kailua Kona, Hawaii, out of a desire to offer patients a personalized expert visit for their skin concerns. Dr. Scheel’s vision has been achieved by creating a practice that includes state of the art technology, a caring staff, a beautiful office, time to listen to her patients’ concerns, and customized treatment plans. Her initial dermatology consultations are 25 to 40 minutes versus the national average of only 7.5 minutes.

Dr. Scheel was professionally trained through the University of Texas system. Her undergraduate degree was in pharmacy from UT Austin. She put herself through medical school working nights in the Cardiac Care Unit. In Pharmacy School, she was Pharmacy Council President and gained admission into the Rho Chi Pharmacy Honor Society. She won awards at graduation for the most contributions to the College of Pharmacy and Outstanding Student at the University of Texas.

Her Medical Degree was obtained at the University of Texas Southwestern/Parkland Hospital. While in medical school she volunteered with the Christian Medical and Dental Society, worked as a pharmacist. As a pastime, she enjoyed running with her girlfriends. She graduated at the top of her class earning her admission into Alpha Omega Alpha honor society and a coveted spot in a dermatology-training program.

She did an internship in Internal Medicine and her Residency in Dermatology at the University of Texas Medical Branch. She thrived on the wide variety of training in medical, surgical, and cosmetic dermatology. She was Chief Resident and passed her Board exams in dermatology in 1999, the same year she ran her first marathon.

Dr. Scheel practiced Dermatology in Dallas, Texas with a group medical practice before moving to Hawaii to follow her dream. She initially worked part-time with Kaiser Permanente while setting up her own Dermatology office in Kailua Kona.

Dr. Scheel stays active in her field by attending national conferences and advanced training seminars to ensure that she brings the latest in skincare to our Big Island. She completes over 50 hours in continuing education each year to stay current; a value well above the minimum required standards.

Dr. Scheel speaks at local and national meetings on many aspects of dermatology. She has given presentations about skin cancer, psoriasis, an exercise in medicine, acne, and more. She is a recognized speaker and physician trainer for Allergan, the makers of Botox and Juvederm.

Dr. Scheel loves the ocean, athletics, community service, her girlfriends, and her chocolate Labrador retrievers! She came to Kona to scuba dive but also found joy in learning to kayak, swim, and stand up paddleboard.

It wasn’t long after arriving in Kona that the triathlon bug bit her. She began doing triathlons when she turned 40. She was able to meet her goals of completing Ironman Canada and the Ironman World Championship race in Kona before 45 years old.

She was the Board President for PATH, Peoples Advocacy for Trails Hawaii, and one of her passions is to see greenways preserved on our island.

Testimonials & Reviews

One of the best things about Hawaii is the sense of community. People are welcoming, friendly and accept everyone as part of their family. We also think of our patients as family members and work hard to make them happy. Below are just some of the testimonials we’ve received from happy patients.

"Tobie at the hilo office was amazing. She made my first facial a wonderful experience. Her knowledge of products, and explanation of each step she performed on me was awesome. I walked out of the office feeling like a brand new women. I recommended Tobie to a few of my friends and coworkers to. She's that good at what she does. Thank you so much Tobie, can't wait to go back for my second treatment. You rock girl!"
-Sabrina G.
"Since the pandemic, I have been getting maskne. I've had two diamond glow facial from Dayna in Waimea. I can already see a difference in my face. Dayna is friendly, efficient and knowledgeable. Thank you and can't wait for my next appointment!" -Bernadette V.
"Dr. Monica Scheel and her staff are the best medical practitioners I’ve experienced during my 70 trips around the sun. Too often, medical offices with great doctors are poorly run - wait a long time - sometimes hours - beyond my appointment time to see the physician, only to get a perfunctory exam and a few minutes. Med schools can train the best docs, but the business management and marketing skills they need to run a practic get short shrift. Unlike too many others, Dr Scheel’s office runs like a Swiss watch - always on time - yet there is never a rush to get me in & out. The nurses, Physician’s Assistants, and Dr Scheel are unfailingly gracious, and thorough in their examinations and discussions about treatments and procedures. I highly recommend Dr. Monica Scheel Dermatology, and have referred friends and associates to her office." - Jim O.
"Very impressed by the beautiful office and professional staff. Kerry did an amazing job on my first appointment and is so sweet and very thorough! Specifically requested her for all of my upcoming sessions!"
- Kamalani

"The Hilo office staff are great! I did a Dermaplane + Diamond glow with Tobie and she is really amazing plus informative. She explains everything throughout the process and it went so smoothly."
-Kawehi N.

"Wonderful to have an office right here in Hilo! Office staff very nice and friendly! Dr. Brooks Hammond was great! Very kind and compassionate." - Wayne P.

Was it just a scratch, a cut that wasn’t healing properly? That is what it seemed like. Thankfully I had a skin check already scheduled with PA Trisha. She didn’t like how it looked and explained how wounds that don’t heal can in fact be precancerous. She did a scrape and indeed, the biopsy came back positive for squamous cell carcinoma. Thankful for Dr Scheel and her staff building awareness in all of us to be on the lookout for anything on our skin that just “doesn’t seem normal.” My advice - schedule an appointment for a skin check! Thank you Refresh team!

I saw PA Brooks for my full skin check as well as my dysport and he is amazing at both medical and cosmetic visits! I have also seen Casey a few times for the new diamondglow facials as well as microneedling and she is very professional and knowledgeable about skincare.
