About Us

Hanna Roewer, MSN, FNP-BC.


     I would like to take the opportunity to personally thank you for visiting the IV HYDRATION and Beyond website. Educationally, I graduated with honors and received my Bachelors in Nursing from Far Eastern University in the Philippines. Immediately after graduation, I moved to Chicago and practiced as a registered nurse (RN) from 2008 to 2015.  While I was an RN in Chicago, I worked in numerous settings which included: Medical Surgical floors, Cardiac Step Down, Post-Anesthesia Care (PACU), as well Float-Pool (while I was attending graduate school).

     In 2015, I received my Master’s Degree in Family Nurse Practitioning and graduated Sigma Theta Tau from North Park University in Chicago.  

     In 2016, my family and I moved to beautiful Central California. For a few years, I was a Family Nurse Practitioner at Mee Memorial Family Practice Clinic in King City and am currently a Family Nurse Practitioner at Community Health Centers of the Central Coast (CHC) in Atascadero.

     As an Advanced Practice Nurse, it is my goal to provide high-quality care to the patients I have the privilege of serving. No matter what setting I am working-in, my main emphasis is always concentrated around health promotion and/ or disease prevention through patient education and coordination of care, whenever it’s possible.

     With that being-said, I decided to start an IV Hydration and Vitamin Infusion Lounge in Paso Robles. I strongly believe in IV vitamin therapy and vitamin injection supplementation. It is my goal to offer this high-quality service-line in the Paso Robles community as a means to promote health, wellness, disease prevention, and to potentially treat patients fighting certain illnesses.

     Since I am currently practicing as a Family Nurse Practitioner, I am only going to be open on Fridays, Saturdays, Sundays, holidays (especially the morning after major holidays), and by appointment-only.  Due to a shortage of primary care services in the Central Coast, I believe it would be a huge disservice to the patients I have the privilege of serving to leave my current position at CHC.  In addition, I understand that many people in the community work Monday through Friday during business hours. With that being said, it is my goal to offer you this service-line outside of regular business hours, especially if you have a busy schedule like me. With that being said, please call if you need services outside of our regular business hours and I will do what I can to accommodate your needs. 

     If you have any questions or concerns, please don’t hesitate to call/ text me at (805) 769-4001.

Douglas Roewer, BSN, RN.


     I would also like to take the time to thank you for visiting the IV HYDRATION and Beyond website. Educationally, I graduated from Oakton Community College in Des Plaines, IL. in 2006 with my Associates Degree in Nursing (ADN) and graduated from Purdue University in West Lafayette, IN. in 2016 with my Bachelor of Science in Nursing (BSN).  

     For the majority of my nursing career, my concentration has been in the field of Gastroenterology (a/k/a. GI).  For approximately 8 years, I was a nurse in one of the most respected GI programs in the northern suburbs of the Chicagoland area with expertise in assisting with general GI procedures, therapeutic GI procedures, and education. 

     In 2016, I was asked to move from Chicago to Central California to help develop an Advanced GI Program at Sierra Vista Regional Medical Center in San Luis Obispo. Currently, I am the Manager of GI Services at Sierra Vista Regional Medical Center. 

     To this day, I find San Luis Obispo County one of the most beautiful places that currently exists in the world with some of the nicest people I’ve ever met in my life.  I strongly believe in offering medical services to those in-need.  Just like Hanna, I also believe it would be a huge disservice to the community if I leave my current position at Sierra Vista, so I will be supporting IV Hydration and Beyond on Saturdays, Sundays, holidays, the day after major holidays, as well as special accommodations by appointment.

    I think it is wonderful that Hanna wants to bring this service line to Paso Robles, and it’s my pleasure to support her in whatever way I can.  You can also call/ text me at (805) 769-4001 if you have any questions, comments, or concerns. It would be my pleasure to talk with you.
