About Our Practice

Dr. Mishner began practicing Internal Medicine in Baltimore, Maryland in 1983 until relocating to Sarasota, Florida in 2003.

Dr. Kassabov began her OB-GYN practice in 1997 in Bulgaria before immigrating to the United States. She then trained in Fort Wayne, Indiana where she became certified to practice Family Medicine.

Both doctors share a philosophy of preventive medicine-that it is “much less costly to teach wellness than treat illnesses. In addition to our standard examination and consultation rooms, our office also has a conference room, physical therapy, massage therapy, a registered dietician and our unique one of a kind gym, staffed by certified fitness trainers. All programs are under the direct supervision of the physicians.

Our Medically Supervised Wellness Programs are very exciting because our patients are offered a safe and healthy way not only to lose weight but to help keep it off. Our physical therapist is Dr. Jill Rose and our Wellness Supervisor is Jennifer Dziob. Christine Aikman is our Registered Dietician and is available for consultations. Some of these program may be covered by insurance.

All patients older than 12 years old are welcome to our practice.

Our beautiful and professionally decorated office is located right in the heart of Lakewood Ranch, Florida on the Southeast corner of Lakewood Ranch Boulevard and State Road 70. All of our wellness programs are located in the same office where we provide conventional healthcare.
