MBA after PhD?

Hi,

1. Basic Demographic info: Male, 31, Indian

2. Educational Background: Currently doing my Phd in Physiology in a US University, GPA= 3.4/4.0

3. Work Experience: Worked in a NGO diagnostic lab for 2 years in India.

4.Extracurriculars: Editor of school magazine, Editor of college magazine, served as Cultural secretary for the Indian association at my current University.

5) Short/Long term goals: I am interested in working in a healthcare/pharmaceutical company and would like to pursue a major in health care management and international business .

These are my concerns
a. by the time I am done with my PhD I will be 33 years old. Most of the B-schools in U.S. have an average of 27/28 years, some being even younger,
b. the only experience I have had is working for 2 years in a small lab back home in India.

Naturally, my concerns are that am I too old for a B-school and is my background a big deterrent. I have considered doing a part-time MBA while working, but if I understand correctly it does not allow you to network as a full time MBA, and networking is very important to land a good job. Also, I am not sure if a part-time MBA carries the same value as a full-time MBA. Another concern is that a part-time MBA may not be a good option for someone like me who is trying to switch into a radically different field. Any thoughts on these?

I have always been a good student and was hoping that if I take finance, economics and advance statistics classes, I can show them that I can adjust to a very different program. I was under the impression that PhD is an independent venture, as it requires planning, co-ordination, and collaboration among different individuals might be able to balance the scale. Do you think asking admissions office of B-schools directly will help?

Any thoughts will be highly appreciated. Thanks.
