Katie has spent the past few years working in the Functional Medicine and MedSpa industries.  She loves helping people to look and feel their best.  Currently, you will find her at the Front Desk and is thrilled to be working alongside Mark and the amazingly talented staff and wonderful clients at Xanadu.

Katie’s passion for helping others has been evident throughout her working career.  From working with people who have disabilities, to becoming a Children’s Director at her church, to launching a non-profit organization that helps rescue children around the world from Human Trafficking, Katie truly loves using her gifts to help others.

In her spare time, Katie is found snuggling on her couch with her Australian Cattle Dog, Trina or is out on Horsetooth paddle boarding and kayaking with her husband and daughter.  Her son attends college in Arizona.  Katie has decided to further her career and has gone back to school to become certified and licensed in Aesthetic Laser & Light Based Procedures.

Aesthetic Nurse Practitioner Injector/Provider

Melanie Zimmermann received a Bachelor of Science in Human Development from Colorado State University. After working as a Social Case Worker for five years, she then began her nursing education attending Front Range Community College, and soon after received her BSN at the University of Texas. While working as a Registered Nurse, Melanie gained experience working in outpatient surgery centers in perioperative areas, in the emergency room, and infusion nursing. Her interest in the aesthetics field prompted her to attend The National Laser Institute in Dallas, Texas where she received certifications in neurotoxin injectables as well as dermal fillers. Upon completing graduate school and receiving her Masters in Nursing as a Family Nurse Practitioner, Melanie continued broadening her interest in aesthetics, adding hormone replacement therapies, weight loss treatments, and vitamin infusions to her repertoire. Her knowledge and experience make her a valuable asset to our Fort Collins med spa.

She is excited to start her career in her hometown and pursue her passion in the beauty and skincare industry while applying her medical background.  She worked shortly at Beauty Bar / Luxe Aesthetic before joining the Xanadu Med Spa Family.  Her attention to detail and conservative, yet effective, approach allows her to tailor treatment plans that fit a patient’s needs and desires, yielding in aesthetically pleasing outcomes.

She earned her Bachelor of Science in Nursing from Michigan State University and is currently pursuing her Master of Science in Nursing Practice at Regis University. Theresa is a certified neurotoxin and dermal filler injector through the National Laser Institute.

It is Theresa’s strong belief that your appearance matters because it affects how you feel about yourself, and how you feel about yourself is directly connected to how you show up for yourself. She wants every one of her clients to feel amazing and translate that energy into living a full, whole-hearted, no apologies kind of life!

Traditional Manual Therapist & Registered Massage Therapist

Helen’s passion and unique manual therapy approach provide a gentle, caring, holistic restoration of the inherent self-healing and regulation mechanism of your body. Over time, your body lessens this ability due to the process of aging, illness, trauma, repetitive injury, surgical scarring, postural imbalances, emotion, and mental and spiritual stresses.

The goal of each session is to precisely assess and address the root cause instead of the symptoms.  The session includes a full assessment, manual manipulation and integration.  Modalities such as muscle energy, cranio-sacral, fascial normalization, organic manipulation, and active stretching combine to restore the balance of fluids and tissues.

Helen’s 25 years of experience and education in Manual Osteopathy (Canadian College of Osteopathy), Massage Therapy (2200 hour Canadian training), Acupuncture, Personal Fitness Training (NASM), and Reflexology are beneficial for those who have tried “everything” and still have pain or dysfunction that prevents living life to the fullest.


Licensed Aesthetician and Massage Therapist

Hello there! My name is Griffy (GRIF-fee) Lové (LUV-ay)!

From a young age, I have had a drive to help others and a dream of becoming a healer. Over the last few years, those passionate desires were achieved! With ambitions to always continue learning, I aspire to help as many people as I can relax and help manage the effects of daily stress upon the body.  I have interests in several eastern modalities in the therapeutic world of healing as well as western modalities I’d like to add to my certifications to be the best healer I can be. When it comes to the world of esthetics, I’m always passionate about giving 1000%.

– “I love what I do, so I don’t see this as work. Best part of my day is taking someone who is stressed from their day to day responsibilities or maybe they just haven’t had a good day in a while – and I help them to finally relax and unwind. It’s a truly beautiful thing.”

Unicorns, Nature and Crystals are a few of my likes along with an enjoyment of the grand outdoors while photography, gardening, writing, hiking (and a plethora of geeky interests like anime and gaming) are just a few of the ways I like to spend my free time. With a calling to heal, I strive to help others sparkle on the inside and out; because everyone deserves to feel like a pampered unicorn. 🙂


Licensed Massage Therapist

My appreciation of how incredible the human body is, started almost 30 years ago (January 1991) when I began a lifetime journey in Martial Arts. That appreciation has grown over the course of my life but no other experience has had more of an impact than when I went through a Below Knee Amputation (BKA – Right Side) September 2014. It was through my physical therapy that I truly began understanding how amazing the human body is and what it does to try to stay in balance. While putting in 1,000+ hours of physical therapy/rehab I was also afforded weekly massage therapy sessions to aid in my recovery. Those sessions fueled my desire to “give back”, to help others in any way that I could. For the majority of my life I’ve enjoyed helping or serving others but the area I’m most proud of is my time in uniform serving in the US Military (Air Force and Army).

Through the amazing instructors at my Therapeutic Massage Therapy school, my love of and appreciation for the human body grew even more. I wasted no time finding a mentor(s) and work with at least one of them twice a month to keep learning, growing and striving to elevate my ability to help my clients. While I do enjoy offering clients a relaxing massage experience I also enjoy the challenges of therapeutic work where I can find and address issues that weigh on the minds of my clients or they feel are holding them back from feeling their best. Stress can be melted away in most all modalities and there’s something very satisfying about providing such a relaxing experience that a client falls asleep on the table. No matter the type of massage I’m providing, I always bring 100% of my abilities to each session.

When I’m not helping clients I enjoy many different activities such as, but not limited to: photography, martial arts, hiking, motocross (where I’m the only regular Amputee racer in the state of CO), yoga, snow skiing, boxing or just relaxing with friends. I feel that my active lifestyle helps me in my work as a Licensed Massage Therapist because I can understand the demands some people put on their bodies and how to address those individual concerns they have & strive to help them get the most out of their bodies.  Thank you for checking-in, I look forward to helping you however I can.
