Dr. McCall Zenker, PharmD
I was born and raised in New England, ND. Upon graduating high school, I attended NDSU where I earned a doctorate degree in pharmacy. I spent the next 15 years working as a pharmacist in the Bismarck/Mandan area. In 2010 I married my high school sweetheart, TeeJay. We have four children, three boys and one girl. Most of our days are spent supporting our kids in their many activities. We went from school to piano lessons to basketball to baseball to football to golf to gymnastics and finally one day TeeJay and I looked at each other wondering when we’d have time for ourselves. Then through our laughter we wondered “how many others are feeling the same?” We have an education in healthcare and a passion for wellness. Now, we want to give back to the community by providing the opportunity for wellness that everyone deserves.
Amber Lauf, LMT
I have been a licensed massage therapist for almost 19 years. I specialize in therapeutic deep tissue massage. Neuromuscular and sports massage techniques are often used to assist in clients healing. Recently I have completed the requirements and training course on basic laser techniques and clinical applications including the safety, science, and clinical applications of the Aspen Laser System. I have incorporated the photobiomodulation laser (light laser) successfully into my practice. It has had positive effects with knee injuries, knee replacements, lower back, ankles, hands and feet, necks, TMJ (jaw) and throat problems.

Brittany Achtenberg, RN
I have been a nurse for 13 years and currently an Aesthetic Registered Nurse with Therapy Retreat. I have a Bachelor of Science in Nursing from Medcenter One College of Nursing in North Dakota. My nursing career has taken me into medical fields of Cardiology, Dermatology, and Aesthetic and Alternative Medicine. Aesthetics and Alternative medicine have become my passion. I love aesthetic nursing because it allows me to help people feel more confident in their own skin and address their concerns from the outside in. I am passionate about teaching and educating patients to help provide them with the building blocks they need to make the best-informed decisions regarding their treatment plan. I am certified in body contouring, laser procedures, IV therapy, cosmetic procedures, microneedling, and PEMF technology. I will be starting my education journey to be a Nurse Practitioner in the fall of 2024.
