Dr. Jeffrey Brown DC, MHA
Assistant Professor, Chiropractic Medicine

Hello, my name is Dr. Jeffrey Brown D.C. MHA. CSSGB. CAc. I was born in Livonia, Michigan, and at the age of 21, relocated to West Palm Beach, Florida. I started my academic career at Palm Beach State College in 1994 with a degree in Pre-Med. I then moved to Atlanta, Georgia in 1998 and attended Life University School of Chiropractic where I obtained my Bachelors in Biology and my Doctorate in Chiropractic Medicine, graduating in 2002. I moved back to South Florida in May 2002 where my Chiropractic journey began. I went into private practice in 2004, where I opened Brown Family Chiropractic Center in Jensen Beach and was the CEO and practicing physician. I ran a very successful practice for the past 18 years, specializing in quality, value, and patient satisfaction. In 2021, I decided to go back to school at Florida Atlantic University to obtain an Executive Masters Degree in Healthcare administration where I graduated in December 2022. I sold my practice in May of 2022, so I could pursue other areas of chiropractic, such as teaching and operations. I am very excited to start my journey here at Keiser University School of Chiropractic as the mission and vision statement of Keiser University align with my own personal values. I am looking forward to working with students, faculty, and administration. I believe with my many years of experience, I will be able to help students become the best Chiropractors they can be while serving the community in which they reside. I have been married to my wife Josephine for the past 28 years, and we have 2 dogs Mia and Steve. I am an avid golfer, and have been with the same golf league for the past 20 years. I am looking forward to getting to know each and everyone at Keiser University School of Chiropractic and believe I will be a key player in your success as a Chiropractic Physician.
