Dr. Karolina Stojanovic

PharmD | Co-Founder

About Dr. Karolina

Karolina is a Doctor of Pharmacy with over 15 years of experience built across community pharmacy, specialty care, and her own practice in Chicago. Specializing in compounding, peptides, and hormones, she’s focused her work on helping people reach their fullest potential in mind and body.

That led her to co-found Freeze & Float with her husband, centered on recovery. The vision expanded and they wanted to create a space where longevity care is personalized, integrated, and designed around cultivating vitality. Nūva Haus emerged from there.

At the Haus, Karolina leads with pharmaceutical precision and a deep care for the people she serves. Every therapy is curated with the same rigor. Known for personally checking in after your hormone protocols start, or following up on NAD+ sessions, she stays involved in each client’s journey. Precision matters. So does being seen and heard.

Outside the Haus, you’ll find Karolina with her two kids, stealing time for a quick pilates class, an infrared sauna session, catching up on the latest research, and finding quiet minutes to meditate.

As the body’s largest organ, skin deserves intentional, individualized care focused on long-term health and balance.

Every service is tailored to your unique skin needs and performed with precision, care, and a commitment to results.

Lily Vasic, LMT

Licensed Massage Therapist

About Lily

I’ve spent the last 26 years dedicating my life to the art of therapeutic healing through massage. I am a graduate of the European Healing Massage Therapy School, and my philosophy is simple: massage should do more than relax you, it should help you heal and leave you feeling genuinely improved.

Every session I give is intentional and customized. I work with a wide range of techniques, including deep tissue, sports massage, cupping, reflexology, hot stone therapy, trigger point therapy, prenatal massage, and lymphatic drainage. I listen closely to your body and your goals, combining modalities to create results you can truly feel.

I also specialize in working with post-operative clients, helping to reduce surgical swelling, improve circulation, and support a smoother, more comfortable recovery through gentle, effective lymphatic techniques.

One of my signature offerings is a custom cellulite reduction treatment I created after years of hands-on experience. This technique blends cupping with targeted bodywork to stimulate circulation and address stubborn cellulite. While it can be intense at times, the results are powerful and many clients see and feel noticeable improvements.

My approach is holistic, honest, and result-driven. Whether you’re seeking relief from pain, post-surgical support, improved circulation, or visible body contouring, my goal is for you to leave each session feeling lighter, better, and more connected to your body.

If you’re ready to experience massage therapy that goes beyond relaxation and truly supports your wellness journey, I would be honored to work with you.
