Erin Thomas Panian

Pharm.D., BCPS Compounding Pharmacist

After receiving my Doctor of Pharmacy degree in 2005, I became a board certified pharmacotherapy specialist in 2006, and have been a compounding pharmacist ever since.  I love combining old school apothecary techniques with modern equipment and figuring out the best individualized medication for a patient.  I try to make sure to combine a wholistic lifestyle and optimal supplementation with compounded medication therapy to reach the best patient outcome.

When I’m not figuring out the best concoction for a patient, you can probably find me at a St. Louis Cardinals or Kansas City Chiefs game or backpacking through the woods with my husband Bobby, stepdaughter Cora, and 3 dogs.  Everyone needs some trees in their life!

RPh, Pharmacist-in-Charge / Compliance Officer

After receiving a BS from St. Louis College of Pharmacy, I started my pharmacy career in a retail pharmacy where I worked, and eventually managed, for 11 years.  After the pharmacy added compounding to its services, I realized how much I enjoyed that aspect of pharmacy.  This began my desire to do even more compounding.  I have been at a pharmacy that operates fully in the field of compounding since 2012, and I have been with Genesis Pharmacy Services since its inception.  Little did I know how much fun it would be to work at Genesis, where I get to wear numerous hats.  Whether I am maintaining multi-state licensure, checking prescriptions, fixing broken machines, doing construction, or maintaining the facilities, there is never a dull moment here.

In my “off time,” I teach St. Louis College of Pharmacy students about the science of compounding.  I am an avid St. Louis Cardinals fan since birth, and I also enjoy following the St. Louis Blues with my oldest son.  I enjoy spending as much time with my wife and three children as possible, which usually includes games, movies, and/or eating.

Tiffany Spudich

Pharm.D., Compounding Pharmacist / Hormone Specialist

I have had the pleasure in specializing in compounding for over 12 years. I began my education path at University of Missouri-Columbia studying biology and chemistry, which lead me down the education path to the St. Louis College of Pharmacy to pursue my doctorate of pharmacy. After graduation, I worked as a pharmacist for the inpatient pharmacy at Mercy Hospital, primarily servicing the intensive care and cardiac units.

I have always been intrigued by the compounding component of pharmacy, which started with  preparation of intravenous medications in the hospital setting, so I decided to pursue a focus in compounding. With years of experience in both a hospital environment and retail pharmacy, I have now worked here at Genesis Pharmacy Services for over 2 years.

I truly enjoy the personal touch on lives an independent compounding pharmacy can provide. Genesis Pharmacy has been the perfect home for me, especially in the high level of service and assistance we love and strive to provide to each and every one of our patients, human and animal.  The challenges and joys of compounding pharmacy fall high amongst my passions, along with spending time with my family and friends, attending concerts, biking, and traveling.
